A novel subjective-objective approach for assessment of tire performance

Dr Giovanni Caputi-Gennaro
Vehicle dynamics - tire development engineer
Automobili Lamborghini SpA
ITALY
A novel methodology is proposed for evaluation of tire performance by vehicle testing. The core of the methodology is a combined subjective-objective test approach. Unconstrained maneuvers performed by factory drivers are processed to isolate bits of significant statistics about tire behavior. A distinguishing feature of such a perspective is that no attempt is made to correlate subjective ratings with the usual vehicle dynamics KPI. Indeed, tailored metrics are defined in order to address vehicle handling issues, claimed to be the most significant by Lamborghini factory drivers. The reliability and physical consistency of the outcomes are promising. The presentation will discuss potential implications for tire development and tire virtual models optimization.

Tires and road surfaces in the age of electric vehicles

Dr Ulf Sandberg
Senior research scientist
Swedish National Road and Transport Research Institute (VTI)
SWEDEN
With the shift from fossil-fuel vehicles to electric vehicles, which is expected in the next few decades, tires will have to be optimized somewhat differently than today. The most important change in optimization may be the increased focus on low rolling resistance, as this allows a greater operating range until recharging. It will be more important to keep inflation optimal for reducing rolling resistance, while not sacrificing other performances, which calls for more precise inflation pressure sensors and monitoring in the vehicle. Tire treads are likely to be thinner and have lower hysteresis losses. Airless tires may provide some solutions.

Influence of morphology and fillers on the aging of rubber blends

Prof Ulrich Giese
Managing director
Deutsches Institut für Kautschuktechnologie eV
GERMANY
The aging stability of the properties of modern tire compounds is particularly important for the actual situation of p-phenylendiamines as environmentally critical substances. For improvement of the elastomer properties, different rubbers are usually combined in a blend system. The effect on the aging behavior is investigated in dependency on the type of rubbers, the blend morphology and blend ratio using different chemical analytical methods and micro indentation for high spatial resolution. Furthermore, the effect of fillers is investigated. Fillers have a limiting effect on the DLO effect or they play a role as oxygen carrier or catalyst.

Mechanical properties of reinforced rubber by conventional filler and cellulose-nanofiber

Tomoyuki Sakai
Manager
The Yokohama Rubber Co Ltd
JAPAN
Yokohama Rubber Co Ltd has been researching sustainable materials for rubber as one of the eco-friendly companies. We prepared reinforced SBR by conventional fillers with a little addition of TEMPO oxidized cellulose nanofibers (TOCN), which were modified from paper pulp. The tensile stress of the reinforced rubbers markedly increased without a decrease in fracture characteristics. We will discuss how to improve their mechanical properties by microscopic observation and by examining the bound rubber of the interface between SBR matrix rubber and TOCN.

Non-destructive innovative methodologies for tire characterization at UniNa Tyre Lab

Dr Antonio Maiorano
PhD student
University of Naples Federico II
ITALY
Knowledge of tires tread viscoelastic behavior is fundamental for the optimization of vehicle performance and safety. These properties are usually characterized by means of DMA applied to a tire tread sample. Therefore, the possibility to perform non-destructive analyses is an attractive solution in automotive for cost, time and integrity reasons. In recent years new methodologies, illustrated in the presentation, have been deeply investigated at UniNa Tyre Lab to characterize a tire within the temperature and frequency ranges of interest and extrapolate the final master curves for tire block – road modeling.

Resin-polymer compatibility and partitioning as a tool for optimizing tread

Gennaro Della Vecchia
Group leader application development and technical service for tire additives in Europe and the Americas
Eastman Chemical Company
BELGIUM
Compatibility between a hydrocarbon resin and a given polymer system strongly depends on the chemical structure of both the resin and the polymer. The impact of polymer-resin compatibility on tire compound performance is examined for both miscible and immiscible polymer blends. Optimized resins can boost dynamic performance, including wet grip, rolling resistance, wear and processing. For immiscible polymer systems, resins can partition between the polymer phases, influencing compound performance and reducing performance trade-offs. Understanding resin-polymer compatibility and resin partitioning can provide insights into potential tread performance and is a powerful tool to help compounders optimize tread formulations.

Functionalized liquid rubber for tire formulations

Daisuke Koda
Polymer development team leader
Kuraray Co Ltd
JAPAN
Kuraray has developed a series of liquid rubber products with molecular weights ranging from a few thousand to a hundred thousand. These polymers, which consist of isoprene, butadiene and styrene and a new, bio-based farnesene, can be used by tire manufacturers to achieve improvements in processing and tire performance. This presentation includes newly developed liquid rubbers with a reactive silane group in the polymer chain that can interact with silica in tire formulations. These liquid rubbers offer, for example, advantageous vehicle fuel economy through reduction in tire rolling resistance.

Process control for the in-situ silanization of silica in tread compounds

Andreas Schröder
Head of AT new technologies
Lanxess Deutschland GmbH
GERMANY
The in-situ silanization of silica in an internal mixer is a temperature-sensitive process. The mixing temperature of the rubber compounds needs to be above 140°C for effective coupling of the silane to the silica surface. On the other hand, sulfur-containing silanes tend to react with the polymer chains above 160°C. The Rhenowave inline process control based on the ultrasound technique is sensitive to both reactions of the silane. The quality control can be done immediately after batch-off by extrusion, preventing scrape.

14:50

In-situ experiments to study cavitation in tire rubber vulcanizates

Eric Euchler
PhD student
Leibniz Institute of Polymer Research
GERMANY
Different experimental techniques were applied to study the mechanical response and failure behavior of styrene-butadiene-rubber (SBR) vulcanizates. Using in-situ dilatometry and x-ray microtomography as well as small-angle-x-ray-scattering experiments, the internal damaging process was characterized in disk-shaped pancake and pre-cracked notched planar specimens, respectively. The number and size of single defects, as well as their integral volume contribution, were studied for unfilled and carbon black reinforced SBR vulcanizates. As a result, microstructural network constraints have an effect on damaging comparable to that induced by geometrical constraints.

Silica-filled wet masterbatch-NR compounds with very low rolling resistance

Dr Gon Seo
Consultant
MiraeSI Company, Korea
KOREA
Silica-filled NR compounds with exceptionally low rolling resistance have been successfully prepared by wet masterbatch (WMB) method using surface-treated hydrophobated silicas. The reaction between amine and glycidyl groups forms organic networks on silica that can be entangled with rubber chains. The addition of the silicas to NR latex followed by mixing and coagulation with acetic acid produces WMB with high silica yields. NR compounds with silica content of 50 phr prepared using WMB showed small tan δ value of ~0.4 at 70℃ without sacrificing mechanical properties due to physical entanglement of rubber with the networks by suppressing irreversible deformation.

Surface-modified carbon black for new opportunities in tread compound design

Dr Hauke Westenberg
Manager compounding rubber
Orion Engineered Carbons GmbH
GERMANY
Novel filler systems developed by Orion Engineered Carbons enable improved rolling resistance indicators like heat build-up, tan δ and rebound at 60°C. Up to 50% in reduction of tan δ was observed while excellent rubber reinforcement required for abrasion resistance was maintained. This is enabled mainly by smart surface modification of the filler, which translates into higher bound rubber at the filler surface. New surface-modified CB grades and compounds containing these grades will be presented. The compounds offer interesting benefits over conventional unmodified carbon black or silica/silane-based rubber.

16:25

Tire polymer simulation for thermo and mechanical property prediction

Dr Caroline Krauter
Senior applications scientist
Schrödinger GmbH
GERMANY
Polymers such as styrene-butadiene copolymers and vulcanized elastomers provide the core properties for tires. The connection between monomer chemistry, polymer microstructure and the network with the properties of the macroscopic materials is critical for the design of better polymeric products. Chemically informed simulation methods provide key tools for building these connections and have been enabled by advances in computing technology. This presentation will review atomistic simulations and coarse-grained modeling used to predict the mechanical and thermodynamic properties of linear and network polymers as well as polymer interfaces.

Functional Low Tg SSBR for winter tire application

Dr Hanjoung Cho
Chief researcher
Korea Kumho Petrochemical (KKPC)
KOREA
The global electric vehicle market is expected to dramatically expand in the near future due to environmental concerns. In rubber compounding, wear resistance is one of the critical properties in EV tires. In order to improve wear performance, functionalized SSBR with low glass transition temperature is required in tire tread compounding. Recently, we have developed the functional low Tg SSBR, which has unique abrasion properties with excellent processability. In this presentation, the polymeric structure and compounding properties of functional low Tg SSBR will be discussed.

Cluster morphology of silica and silanization, Part I: MD simulation

Dr Michael York
Research fellow
Momentive Performance Materials
USA
Controlling the dispersion of precipitated silica in rubber compounds is a significant challenge for achieving consistent mechanical property improvements in polymer nanocomposites. Silica aggregates are immiscible with the organic elastomeric phase. To prevent silica flocculation, the silica surface is hydrophobized by grafting amphiphilic silane molecules. However, the silica aggregates exhibit self-assembly into anisotropic structures depending on the amount of grafted silane per nm2 of silica surface area, which directly affects the mechanical properties of the rubber. Simulations suggest that this self-assembly reflects a balance between the energy gained during silica re-flocculation and the entropy of distorting the grafted OPTES molecules.

Fred Ignatz-Hoover
Technology fellow
Eastman Chemical Company
USA
Eastman has developed process-optimization methodologies utilizing thermal imaging technology and in-compound soluble sulfur analysis with statistical design of experiments. Crystex Cure Pro insoluble sulfur is an engineered product that shows dramatic improvements in flow, dispersion kinetics and thermal stability over conventional products. When Eastman process-optimization methodologies are applied to mixing or calendering operations involving Crystex Cure Pro, dramatic improvements in processing time and energy utilization have been observed. Optimized factory operations have been demonstrated showing capacity and/or energy utilization improvements in the order of 10-40%. This presentation will highlight Eastman methodologies and examples of factory-optimized processes.

11:45

Cluster morphology of silica and silanization, Part II: experimental evaluation

Dr Jorge Lacayo-Pineda
Expert for materials evaluation
Continental Reifen Deutschland GmbH
GERMANY
The optimal level of silanization is a relevant question for optimal product performance. Before hydrophobization, the strong silica-silica interactions induce non-linear effects in the rheological behavior of the rubber compound. FT-Rheology shows a systematic reduction of the non-linearity with increasing level of silanization. The non-linearity increases again after reaching the optimal surface coverage. TEM imaging of silica clusters performed before, after and at the optimal level of silanization show changes in cluster morphology rearranged during mixing. Both types of experiments, TEM and FT-Rheology, were conducted on an experimental SSBR compound using 3-octanoylthio-1-propyltriethoxy silane (OPTES).

The realization of the required properties profile of tires is based on a molecular understanding of the interaction between their components. Characterizing the finished products under load offers a more realistic consideration of the tire performance based on deep insights into the inner structure and the dynamic of the elastomer composites. Only a simultaneous dynamic-mechanical and dielectric analysis using DiPLEXOR allows rubber formulators and finished parts manufacturers a better understanding of damage effects caused by large strains, long-term dynamic loads and high temperatures.

Get a grip: performance of naphthenic oil in winter tires

Dr Kamyar Alavi
Senior technical advisor
Nynas AB
SWEDEN
Naphthenic tire oils have been gaining market share not only thanks to their excellent HSE properties but also due to their high performance as plasticizing oils in tire compounds. While the benchmark low rolling resistance helps increase fuel efficiency, especially in winter tires, naphthenic oils help achieve increasing grip and traction at very low temperatures. In this work, we have reviewed the performance of selected oils in given winter tire formulations and will show how the use of naphthenic oils as plasticizers will contribute to designing high-performance winter tire compounds.

HRS produced from RHA and its impact on car PCT

Paulo Garbelotto
Director of sales and marketing
Oryzasil Silicas
BRAZIL
Oryzasil is one of the first companies producing high-performance silica from RHA, by an effluent-free production process. European tire labeling has focused on displaying information on the fuel efficiency, wet grip and external rolling noise of tires. However, it has recently been shown that tire abrasion and tear contribute considerably to the pollution of the environment by microplastics. Tear and wear resistance of a car tire tread compound can be improved without significantly compromising rolling resistance and wet grip behavior when a highly reinforcing silica made from rice husk ash (Oryzasil HR200MP) is used.

Effect of lithium-catalyzed BR on the performance properties of tire compounds

Dr Mridul Dasgupta
Senior scientist
HASETRI
INDIA
Polybutadiene rubber (BR) is one of the most important rubbers used in tires. It imparts excellent wear resistance to the tread and fatigue life of the sidewall compound of a tire. Different catalyst systems of polymerization govern the microstructure of BR: cobalt, nickel, neodymium give high-cis, whereas lithium gives low-cis BR. Though high-cis BR is widely used in tires, lithium-catalyzed low-cis BR is being tried to meet the challenging requirements of tires. This paper reveals a comparative study of the effect of lithium- and neodymium-catalyzed BR on static and dynamic mechanical properties, and the wear and fatigue crack growth resistance of tread and sidewall compounds of tires.

JK Tyre & Industries Limited
INDIA
The physical properties of filler-rubber composites are greatly affected by the distribution of filler, filler properties and polymer-filler interactions. Understanding of filler dispersion in polymer-filler composite is one of the major research works to establish the properties of tires, such as rolling resistance, grip and mileage. Several characterization techniques are available to understand the filler dispersion in polymer-filler composites, viz. electrical conductivity measurements, bound rubber evaluations, mechanical properties measurements, carbon black surface properties study, small-angle x-ray scattering (SAXS) and nuclear magnetic resonance (NMR) spectroscopy. The primary objective of this paper is to introduce a new characterization technique.

FEAR rheology for rubber materials: the rubber screw rheometer

Dr Myung-Ho Kim
President
MKE Co
KOREA
FEAR – Fast, Easy, Accurate, Reliable – measurement is the key feature of this device. A new rheology measurement for rubber compounds and virgin rubber has been conducted using the rubber screw rheometer. This device uses a new viscometric flow analysis of single-screw extruders to measure shear viscosity, which is based on the ‘closed discharge’ extrusion characteristic equation. It uses a small amount of materials – batch operation. The measured viscosity is a function of shear rate; thus, it can be used for quality control and process design. Measurement results for the relaxation time and scorch time are also exhibited.

Optimization of compounds filled with treated silica

Dr Lucas Dos Santos
Senior research associate
PPG Silica Products
USA
More stringent performance demands are leading to an increase in the use of highly dispersible silica in tire compounds. However, conventional silica technology has a variety of production and performance limitations. Agilon Performance Silicas are treated precipitated silicas that overcome the manufacturing limitations associated with conventional HDS/in-situ silane technology, enabling expansion of the tire magic triangle and reducing VOC emissions. This paper discusses how appropriate silica surface modifications result in a new performance silica technology platform that overcomes these limitations. Results will be presented on how to compound treated silica to increase mixing efficiency and optimize compound performance.

Promoting steel cord adhesion – replacing cobalt salts with hexamethylene bis-Bunte salts

Jeffrey Lin
Associate scientist
Eastman Chemical Company
USA
Replacing cobalt salt in a tire’s steel cord compound with hexamethylene bis-Bunte salt (DHTS) gives comparable steel cord adhesion (SCA) relative to the cobalt salt-containing compound. Based on results, good SCA can be attained with reduced cobalt salts and is generally within the experimental error with a cobalt-neodecanoate-containing compound, and slightly better in the case of steam and salt water. Also, brass-to-rubber interfaces were studied using x-ray photoelectron spectroscopy (XPS), with data indicating the presence of DHTS and in-situ-generated reducing agent. This suggests the Cu and Zn oxidation state can be modulated, leading to improved adhesion.

Fracture analysis of steel cord for tire forensic analysis

Dr Barun Samui
Scientist
Harishankar Singhania Elastomer and Tyre Research Institute (HASETRI)
INDIA
Systematic analysis of service-failed tires is of paramount importance to understand the root causes of the tire failure and take appropriate corrective measures. During the investigation it often becomes extremely challenging to hypothesize the sequence of events that might have occurred prior to the ultimate failure, and it becomes difficult to pin down the root cause of failure. The characteristic nature of ruptures at the fracture point of steel cord filaments is linked to specific causes. The present study is focused on forensic analysis of service-failed tires where steel cords were eventually fractured, to identify the root causes of failure.

Cord adhesion without cobalt and resorcinol and with less zinc

Roberto Blanco Trillo
Business development manager
Allnex
GERMANY
Resorcinol replacements are commonly used in tire compounds to improve adhesion between rubber matrix and the surface of metal inserts while attaining a significant reduction in workplace exposure and no fuming by resorcinol. The next step to reduce environmental concerns is to eliminate not only resorcinol but also cobalt salts by using a zinc-functionalized resin in a masterbatch. The vulcanization speed is attained with significantly reduced zinc levels, and the use of cobalt salts is completely avoided. This approach provides high cord adhesion without cobalt or resorcinol while reducing zinc – a triple green solution.

Analysis of the influence of tread wear on tire characteristics

Benjamin Schäfer
Scientific researcher
Institute for Automotive Engineering (ika)
GERMANY
The simulation of tire characteristics depends on the reproducibility of the measurements used for the parameterization process. The rubber abrasion of these measurements is known to affect some of the tire's key attributes such as cornering stiffness. Using different 3D scan methods, the Institute for Automotive Engineering developed a procedure to investigate the influence of tread wear produced during different parameterization measuring programs on these tire characteristics. The results are then used to improve the parameterization process by defining tread wear thresholds.

What happens in the tire contact patch?

Marzieh Salehi
PhD candidate
University of Twente
NETHERLANDS
The presentation explains how a tire grips the ground. The actual area under load determines the contact pressure and governs proper grip or friction, which is key for safety. Among all specimen geometries for rubber frictional measurements, a wheel shape sample is of great interest. In the first step, the static contact areas and pressures of Grosch wheels on various surface roughness were measured and compared with those of the corresponding real tires. The effect of the in-rubber properties on the contact area was investigated to enhance the insight into the tire contact patch.

Institut für Maschinenelement, Konstruktion und Fertigung, Technische Universität Bergakademie Freiberg
GERMANY
Studying tribological parameters like friction and wear in block rubber in contact with soil can help to reduce wear in tractor tires or other off-road vehicles, which could be used in tire design optimization. In this study, we investigated the effect of rubbers like SBR and NR and real tire material, angle, velocity and normal load on tribological properties in contact with soil. This study provides significant information that can be used by tire developers to extend the lifetime expectancy of off-road tires like tractor tires by minimizing wear in contact with soil.

Some measures of tire wear and tire stiffness, as well as wear impact on maximum grip, are referred to in some scientific papers. The most widely used empirical model (Pacejka Magic Formulae) includes the effect of tire inflation pressure, but the effect of tire wear is not considered yet. The aim of this paper is to quantify the effects of tire wear on tire longitudinal and lateral behavior, to propose a modification of Pacejka Magic Formulae and to understand the influence on the motorcycle lateral and longitudinal dynamic. To achieve this target, numerical and experimental investigations were carried out.

Will Martian rovers ever run on rubber tires?

Dr Rafal Anyszka
Researcher
University of Twente
NETHERLANDS
Designing rubber materials that could withstand harsh Martian conditions is a challenging task. Space radiation severely damages the chemical structure of rubber macromolecules, and the low average temperature limits the types of applicable rubbers only to those exhibiting very low glass transition temperatures. However, the advantages provided by the unique elastic and dumping properties of rubber have become more attractive in view of the Curiosity rover wheel damage that occurred during Mars exploration, which was due to the poor elastic performance of aluminum used for the tires' construction. This triggers the question: is it technologically feasible to develop rubber compounds for Martian rover tires?

Challenges raised by high-load-capacity tires

Bruno Guimard
Original equipment pre-development program manager
Michelin
FRANCE
Throughout the history of the automotive industry, engineers have worked to implement more features in a limited package, offering more space for drivers and passengers. The emerging electrification of vehicles requires additional space for the batteries while significantly increasing the load of the vehicle. Moreover, OEMs want to keep the possibility to offer a range of wheel diameters for the end customer, especially for sport derivatives. The presentation explains how high-load-capacity tires offer a significant degree of freedom for BEV and PHEV, the XL+ experimental standard proposal, use cases for HLC tires, and technical challenges for HLC.

Tire-road friction estimation using intelligent tires

Utkarsh Gupta
Graduate research assistant
Center for Tire Research, Virginia Tech
USA
Currently, all the existing driver-assist systems lack knowledge of the tire-road contact characteristics and estimation of road friction. This information has a direct effect on vehicle safety and control. A novel approach, based on intelligent tire technology, was developed in this study for tire/road friction estimation. A sensor-fusion algorithm for real-time friction estimation was developed to integrate acceleration data from the two instrumented intelligent tires to reduce the lag between the two tires under different driving maneuvers. Consequently, signal processing and machine learning algorithms were developed to do pattern recognition and estimate the coefficients of friction.

Valorization and scalability of alternative natural rubber through tailoring properties

Dr Katrina Cornish
Professor
The Ohio State University
USA
Alternative natural rubber on a small scale cannot enter the commodity markets served by Hevea brasiliensis rubber. In-depth characterization of guayule rubber has identified distinct physical properties that can be valorized for industrial applications and can access high-value niche markets. Field-grown dandelion rubber is similar to Hevea rubber and most of the rubber coagulates in the roots in vivo. Hydroponics produces dirt-free rubber and may affect the proportion of latex and solid rubber and rubber quality. The establishment of alternative rubbers with matching processing infrastructure for niche markets will allow rapid scale-up to meet tire markets as prices increase.

Tire/road friction: a skid resistance tool based on contact modeling

Dr Malal Kane
Senior researcher
Ifsttar
FRANCE
This paper introduces a new tool for tire/road skid resistance prediction. The tool is based on modeling the dynamic-viscoelastic-rough-lubricated contact. It takes into account all parameters related to tire, road and contact operating conditions: at the tire side, the tools take into account its geometry (width, rim diameter, flank height, tread pattern and depth), inflation pressure, rubber material (viscoelasticity). At the road, its texture is taken into account via the surface topography. At the contact interface, the dry or wet condition can be taken into account. The operating conditions are taken into account via the load, speed and slip ratio.

Automated driving, electrification and shared mobility are shifting the requirements for tire performance. This in turn affects how tires are being tested and modeled to support the development of new tires and vehicles. A self-driving vehicle’s ability to plan and control the vehicle path is heavily dependent on tire force and moment properties, for which existing testing and modeling methodologies can be adapted. However, new technologies such as Tire-as-a-Sensor and road perception and friction estimation require new testing and modeling methods. Examples for both car and truck tires are presented and discussed.

Novel coupling agents for reducing hysteresis loss in rubber/filler compositions

Dr Natsuyo Kamimoto
Researcher

We have developed novel coupling agents SUMILINK100 and SUMILINK200 that are effective for the reduction of hysteresis loss in natural rubber (NR) composites with carbon black (CB). The reduction of hysteresis loss was achieved by the improvement of filler dispersion in rubber composites through the reaction and/or interaction with both rubber and filler. Recently, we interestingly found SUMILINK100 and SUMILINK200 also were effectively applicable to other rubber/filler composites, such as NR/silica and E-SBR/CB composites. In this presentation, we will introduce the related data regarding the performance of our coupling agents on some formulations.

Compounding of silica/silane systems in natural rubber – part II

André Wehmeier
Head of rubber technology group
Evonik Resource Efficiency GmbH

The first part of 'Compounding studies with silica and silanes in NR' was delivered at Tire Technology Expo Conference 2019. Optimum silane levels, especially regarding tensile tests, have been established, dependent on the CTAB surface area of silica. But the adjustment of silane should not be performed in a linear way. In particular, the highest-surface-area silica needs much more silane than expected, resulting in an optimum of moduli and simultaneous elongation at break values on the carbon black level. This second part deals with these optimized silica/silane systems and further optimizations based on a DoE including the accelerator systems.

Alleviating marching modulus in silica-filled tread compounds

Dr Wisut Kaewsakul
Assistant professor
University of Twente
NETHERLANDS
Marching modulus in the vulcanization of rubber compounds is undesirable, since it causes the final properties of the vulcanizates to be instable. This characteristic exhibits a gradual increase in modulus due to a continuous occurrence of the cross-linking reaction, leading to problems in indicating the optimum cure time of a compound. In silica-filled SBR/BR tread compounds including a silane coupling agent, marching modulus occurs to various degrees depending on the quality of mixing of the compounds. This presentation reviews the factors contributing to the marching modulus with suggestions for how to alleviate this phenomenon.

The properties needed for aircraft tire treads are significantly different to the ones required for passenger car or truck tires, for which improvements mainly focus on a better balance of rolling resistance, wet skid resistance and wear resistance. Aircraft tires experience severe operation conditions during service: the temperature can reach the critical temperature of polymers, thus accelerating tread wear and aging. To reduce this temperature degradation, the material should have a low hysteresis. This presentation will focus on the influence of the type of filler and will include adjustment of the processing conditions for optimization of aircraft-tire-related properties.

Is the Velcro concept feasible for an alternative silica/polymer coupling?

Anke Blume
Full professor
University of Twente
NETHERLANDS
A new concept for an alternative silica/polymer coupling system was introduced to the tire industry in 2019 to overcome the disadvantages of the current system. Currently, if the relatively stiff covalent sulfur bridge of the silica/silane/polymer connection is broken, there is no possibility to reconnect. As a consequence, a completely different coupling concept was considered, mimicking the Velcro system known from nature. The tangled and cross-linked rubber macromolecules act as molecular loops, and relatively long elastomer brushes grafted on the silica surface act as molecular hooks. The in-rubber properties will be presented to show the efficiency of this new system.

In this work, we explain how a methodology can be successfully implemented to control the FCG analysis fully automatically. Once the samples are fixed, the measurement is started and works in a self-controlled way until the end. This makes research and development more efficient.

In this study, a common nitrogen curing system that is a well-known method for tire curing was improved. Two major problems with the nitrogen curing system are higher total curing time and the temperature difference between the top and bottom of the curing bladder. In our proposed method, we solved these two problems and also eliminated steam waste in the curing cycle. In this new method, we took advantage of high energy condensate creation at the first step of curing. By circulating this condensate in the bladder using a special process we can optimize the curing cycle. The results show a 40% reduction in total curing time.

Measuring friction to predict tire behavior on different road surfaces

Alexander O'Neill
Research engineer
University of Surrey/Jaguar Land Rover
UK
Most tire models used in vehicle dynamics simulations are parameterized with data obtained on a flat-track, where the tire is commonly driven on sandpaper. The resultant models are typically inaccurate at higher slips, where conditions are dominated by the rubber-road friction characteristics. To improve such tire models, this paper explores the use of tread rubber friction measurements obtained with a purpose-built rubber friction measurement system. Friction measurements were performed under controlled conditions and incorporated into a brush-type tire model. Preliminary results indicate the benefits and potential of detailed knowledge on the frictional behavior for accurately modeling tire forces and moments.

In order to reduce rolling resistance (RR) for better fuel efficiency of tires, the use of solution-polymerized styrene-butadiene copolymer (SSBR) in combination with silane/silica systems in tire treads is successful. Although it is generally difficult for silica to be well-dispersed in hydrophobic rubber matrix due to its high hydrophilicity, Asahi Kasei has developed special functionalized SSBRs that give better silica dispersion due to their unique functionalization technology. In this presentation, the interaction between SSBRs and silica and the positive effect on silica dispersion will be discussed.

New Exxpro specialty elastomer 3563 with superior impermeability for tires

Dr Sunny Jacob
Elastomer technology advisor
ExxonMobil Chemical
USA
Isobutylene elastomers are of great commercial importance in tire applications due to their notable low gas permeability properties attributed to their efficient molecular packing. Brominated isobutylene-co-para-methylstyrene (BIMSM) elastomers are a special class of isobutylene elastomers synthesized by random cationic polymerization of isobutylene and p-methylstyrene (pMS), followed by a selective bromination of the methyl group of the para-methylstyrene units. BIMSM elastomer, commercially known as Exxpro specialty elastomer, exhibits superior heat resistance and aging properties, and is much more resistant to chemicals and ozone than butyl or halobutyl polymers due to its fully saturated backbone structure. This paper will present the chemistry and application aspects of the newly developed BIMSM elastomer, Exxpro specialty elastomer 3563, to meet the growing market demands and requirements for low maintenance, low inflation pressure loss rate (IPLR) tires and tires for connected autonomous shared electric vehicles.

It was found that Exxpro 3563 had lower permeability, better filler dispersion, higher green strength, better heat resistance and better dimensional stability than halobutyl-based innerliners. Tires manufactured with Exxpro 3563 innerliners had lower inflation pressure loss rates (IPLR) than those based on halobutyl innerliners. It is believed that this advantage in air retention will result in better overall tire performance.

The service life of curing bladders is an important property in tire production. Tire manufacturers have a big interest in running a curing bladder for as long as possible in order to produce as many tires as possible with one curing bladder. However, due to extreme temperatures and repeated flexing cycles, the lifetime of a bladder is limited. One reason is an unwanted migration of traditional plasticizers out of the article, which is leading to stiffness issues. The presentation offers new plasticizer types for an extended service life of bladders. Finally, a cost advantage is achieved.

For all-seasons/winter tire development for vehicle OEMs based in Europe, a snow testing session in Scandinavia is needed. Winter testing is possible and economically convenient only in northern Europe in a small timeframe. Therefore, winter tire development is not achievable outside these boundary conditions.

Nevertheless, several factors affect tire performance during coast-down and increase the variability of the results, and not all of them are related to the tire rolling resistance. This study aims at understanding the conditions under which the tire performs the best and provides the lowest resistance, and how this can be translated into a more effective deceleration leading to emissions benefits.

A methodology has been developed to simulate the tire static behavior and estimate its constituent hyperelasticities based on the measured tire responses (radial, longitudinal and lateral stiffness) for the applied static loads. First, a simplified tire numerical model with standard rubber material properties is modeled that can substantively predict the necessary tire static responses. These responses are compared against the physical tire responses that are measured using a kinematic and compliance (K&C) test rig. Finally, a DoE and an optimization process are performed by sampling the rubber hyperelasticies to simulate the FE model and match the tire static test responses precisely.

Generally, lateral stiffness is measured in a static state, so there are very few examples of lateral stiffness measurement during tire rotation. The proposed method makes it possible to measure the force, displacement and stiffness values of the tire footprint in a distributed manner by measuring the force distribution on the contact surface during tire rotation.

Velocity measurements of the water flow in tire grooves

Damien Cabut
PhD student
Ecole Centrale de Lyon
FRANCE
Hydroplaning occurs when a tire encounters more water than it can scatter. Hydrodynamic pressure builds up in front of the tire and induces loss of surface friction, which diminishes the available braking force that it can generate in an emergency braking, for example. Therefore, it is crucial for tire designers to optimize tread designs to ensure the best water evacuation without compromising any other performance. In this work, a measurement method based on particle image velocimetry is proposed to measure the velocity field in the grooves of a worn tire rolling through a water puddle.

In this work, the gap between a model substrate and contacting tire tread compounds is investigated with respect to normal load and sliding speed. A new experimental technique based on laser distance measurements is used to determine the relaxation of a rubber block pressed into asperities, and thus the depth of rubber indentation in static and dynamic conditions. In this way, the results allow a validation of the contact theories and FEM simulations.

Numerical evaluation of tire heat generation and temperature distribution using SSHT

Rajesh Nagose
Senior manager/solution consultant
Dassault Systèmes

Tire performance highly depends on temperature rise during operations because rubber material properties are highly temperature and frequency dependent. Hysteresis loss or viscous energy dissipation is the main contributor to the tire heating as the tires are subject to cyclic loading. This work aims to evaluate tire heat generation and temperature distribution using the steady-state heat transfer (SSHT) solution. The parallel rheological framework (PRF) material model captures the viscous energy dissipation and this output is used to evaluate heat sources for thermal simulation. Heat transfer analysis is performed using this heat source and surface film coefficients boundary conditions.

Real snow roads are exposed to changing conditions such as unstable temperatures or variable snow conditions. These changes have a significant influence on the snow friction of a tire tread block. We intend to quantify these effects experimentally by means of targeted parameter studies. For the parameter studies, we investigate the behavior of a tread block on a linear rolling test rig with variable slip ratios on snow roads. The results show that the temperature has a considerable influence on the snow friction of a tread block. The phenomenon can be explained physically by the temperature-dependent strength of the snow.

Since the need to preserve the environment has become a major driver for the development of tire tread compounds, many attempts have been made to introduce vegetable oils to match performance, processability and sustainability. An important LCA improvement can be achieved using a specifically designed bio-refinery vegetable derivative obtained through a bio-to-bio conversion technology.

A novel methodology is proposed for evaluation of tire performance by vehicle testing. The core of the methodology is a combined subjective-objective test approach. Unconstrained maneuvers performed by factory drivers are processed to isolate bits of significant statistics about tire behavior. A distinguishing feature of such a perspective is that no attempt is made to correlate subjective ratings with the usual vehicle dynamics KPI. Indeed, tailored metrics are defined in order to address vehicle handling issues, claimed to be the most significant by Lamborghini factory drivers. The reliability and physical consistency of the outcomes are promising. The presentation will discuss potential implications for tire development and tire virtual models optimization.

Tires and road surfaces in the age of electric vehicles

Dr Ulf Sandberg
Senior research scientist
Swedish National Road and Transport Research Institute (VTI)
SWEDEN
With the shift from fossil-fuel vehicles to electric vehicles, which is expected in the next few decades, tires will have to be optimized somewhat differently than today. The most important change in optimization may be the increased focus on low rolling resistance, as this allows a greater operating range until recharging. It will be more important to keep inflation optimal for reducing rolling resistance, while not sacrificing other performances, which calls for more precise inflation pressure sensors and monitoring in the vehicle. Tire treads are likely to be thinner and have lower hysteresis losses. Airless tires may provide some solutions.

Tire-road friction estimation using intelligent tires

Utkarsh Gupta

Currently, all the existing driver-assist systems lack knowledge of the tire-road contact characteristics and estimation of road friction. This information has a direct effect on vehicle safety and control. A novel approach, based on intelligent tire technology, was developed in this study for tire/road friction estimation. A sensor-fusion algorithm for real-time friction estimation was developed to integrate acceleration data from the two instrumented intelligent tires to reduce the lag between the two tires under different driving maneuvers. Consequently, signal processing and machine learning algorithms were developed to do pattern recognition and estimate the coefficients of friction.

Field-grown dandelion rubber is similar to Hevea rubber and most of the rubber coagulates in the roots in vivo. Hydroponics produces dirt-free rubber and may affect the proportion of latex and solid rubber and rubber quality. The establishment of alternative rubbers with matching processing infrastructure for niche markets will allow rapid scale-up to meet tire markets as prices increase.

This paper introduces a new tool for tire/road skid resistance prediction. The tool is based on modeling the dynamic-viscoelastic-rough-lubricated contact. It takes into account all parameters related to tire, road and contact operating conditions: at the tire side, the tools take into account its geometry (width, rim diameter, flank height, tread pattern and depth), inflation pressure, rubber material (viscoelasticity). At the road, its texture is taken into account via the surface topography. At the contact interface, the dry or wet condition can be taken into account. The operating conditions are taken into account via the load, speed and slip ratio.

Compatibility between a hydrocarbon resin and a given polymer system strongly depends on the chemical structure of both the resin and the polymer. The impact of polymer-resin compatibility on tire compound performance is examined for both miscible and immiscible polymer blends. Optimized resins can boost dynamic performance, including wet grip, rolling resistance, wear and processing. For immiscible polymer systems, resins can partition between the polymer phases, influencing compound performance and reducing performance trade-offs. Understanding resin-polymer compatibility and resin partitioning can provide insights into potential tread performance and is a powerful tool to help compounders optimize tread formulations.

Process control for the in-situ silanization of silica in tread compounds

Andreas Schröder
Head of AT new technologies
Lanxess Deutschland GmbH

The in-situ silanization of silica in an internal mixer is a temperature-sensitive process. The mixing temperature of the rubber compounds needs to be above 140°C for effective coupling of the silane to the silica surface. On the other hand, sulfur-containing silanes tend to react with the polymer chains above 160°C. The Rhenowave inline process control based on the ultrasound technique is sensitive to both reactions of the silane. The quality control can be done immediately after batch-off by extrusion, preventing scrape.

Cluster morphology of silica and silanization, Part I: MD simulation

Dr Michael York
Research fellow
Momentive Performance Materials
USA
Controlling the dispersion of precipitated silica in rubber compounds is a significant challenge for achieving consistent mechanical property improvements in polymer nanocomposites. Silica aggregates are immiscible with the organic elastomeric phase. To prevent silica flocculation, the silica surface is hydrophobized by grafting amphiphilic silane molecules. However, the silica aggregates exhibit self-assembly into anisotropic structures depending on the amount of grafted silane per nm2 of silica surface area, which directly affects the mechanical properties of the rubber. Simulations suggest that this self-assembly reflects a balance between the energy gained during silica re-flocculation and the entropy of distorting the grafted OPTES molecules.

Cluster morphology of silica and silanization, Part II: experimental evaluation

Dr Jorge Lacayo-Pineda
Expert for materials evaluation

The optimal level of silanization is a relevant question for optimal product performance. Before hydrophobization, the strong silica-silica interactions induce non-linear effects in the rheological behavior of the rubber compound. FT-Rheology shows a systematic reduction of the non-linearity with increasing level of silanization. The non-linearity increases again after reaching the optimal surface coverage. TEM imaging of silica clusters performed before, after and at the optimal level of silanization show changes in cluster morphology rearranged during mixing. Both types of experiments, TEM and FT-Rheology, were conducted on an experimental SSBR compound using 3-octanoylthio-1-propyltriethoxy silane (OPTES).

While the benchmark low rolling resistance helps increase fuel efficiency, especially in winter tires, naphthenic oils help achieve increasing grip and traction at very low temperatures. In this work, we have reviewed the performance of selected oils in given winter tire formulations and will show how the use of naphthenic oils as plasticizers will contribute to designing high-performance winter tire compounds.

HRS produced from RHA and its impact on car PCT

Paulo Garbelotto
Director of sales and marketing
Oryzasil Silicas
BRAZIL
Oryzasil is one of the first companies producing high-performance silica from RHA, by an effluent-free production process. European tire labeling has focused on displaying information on the fuel efficiency, wet grip and external rolling noise of tires. However, it has recently been shown that tire abrasion and tear contribute considerably to the pollution of the environment by microplastics. Tear and wear resistance of a car tire tread compound can be improved without significantly compromising rolling resistance and wet grip behavior when a highly reinforcing silica made from rice husk ash (Oryzasil HR200MP) is used.

Effect of lithium-catalyzed BR on the performance properties of tire compounds

Dr Mridul Dasgupta
Senior scientist
HASETRI
INDIA
Polybutadiene rubber (BR) is one of the most important rubbers used in tires. It imparts excellent wear resistance to the tread and fatigue life of the sidewall compound of a tire. Different catalyst systems of polymerization govern the microstructure of BR: cobalt, nickel, neodymium give high-cis, whereas lithium gives low-cis BR. Though high-cis BR is widely used in tires, lithium-catalyzed low-cis BR is being tried to meet the challenging requirements of tires. This paper reveals a comparative study of the effect of lithium- and neodymium-catalyzed BR on static and dynamic mechanical properties, and the wear and fatigue crack growth resistance of tread and sidewall compounds of tires.

The physical properties of filler-rubber composites are greatly affected by the distribution of filler, filler properties and polymer-filler interactions. Understanding of filler dispersion in polymer-filler composite is one of the major research works to establish the properties of tires, such as rolling resistance, grip and mileage. Several characterization techniques are available to understand the filler dispersion in polymer-filler composites, viz. electrical conductivity measurements, bound rubber evaluations, mechanical properties measurements, carbon black surface properties study, small-angle x-ray scattering (SAXS) and nuclear magnetic resonance (NMR) spectroscopy. The primary objective of this paper is to introduce a new characterization technique.

KOREA
FEAR – Fast, Easy, Accurate, Reliable – measurement is the key feature of this device. A new rheology measurement for rubber compounds and virgin rubber has been conducted using the rubber screw rheometer. This device uses a new viscometric flow analysis of single-screw extruders to measure shear viscosity, which is based on the ‘closed discharge’ extrusion characteristic equation. It uses a small amount of materials – batch operation. The measured viscosity is a function of shear rate; thus, it can be used for quality control and process design. Measurement results for the relaxation time and scorch time are also exhibited.

Optimization of compounds filled with treated silica

Dr Lucas Dos Santos
Senior research associate
PPG Silica Products

More stringent performance demands are leading to an increase in the use of highly dispersible silica in tire compounds. However, conventional silica technology has a variety of production and performance limitations. Agilon Performance Silicas are treated precipitated silicas that overcome the manufacturing limitations associated with conventional HDS/in-situ silane technology, enabling expansion of the tire magic triangle and reducing VOC emissions. This paper discusses how appropriate silica surface modifications result in a new performance silica technology platform that overcomes these limitations. Results will be presented on how to compound treated silica to increase mixing efficiency and optimize compound performance.

Compounding of silica/silane systems in natural rubber – part II

André Wehmeier
Head of rubber technology group
Evonik Resource Efficiency GmbH

The first part of 'Compounding studies with silica and silanes in NR' was delivered at Tire Technology Expo Conference 2019. Optimum silane levels, especially regarding tensile tests, have been established, dependent on the CTAB surface area of silica. But the adjustment of silane should not be performed in a linear way. In particular, the highest-surface-area silica needs much more silane than expected, resulting in an optimum of moduli and simultaneous elongation at break values on the carbon black level. This second part deals with these optimized silica/silane systems and further optimizations based on a DoE including the accelerator systems.

Alleviating marching modulus in silica-filled tread compounds

Dr Wisut Kaewsakul
Assistant professor
University of Twente
NETHERLANDS
Marching modulus in the vulcanization of rubber compounds is undesirable, since it causes the final properties of the vulcanizates to be instable. This characteristic exhibits a gradual increase in modulus due to a continuous occurrence of the cross-linking reaction, leading to problems in indicating the optimum cure time of a compound. In silica-filled SBR/BR tread compounds including a silane coupling agent, marching modulus occurs to various degrees depending on the quality of mixing of the compounds. This presentation reviews the factors contributing to the marching modulus with suggestions for how to alleviate this phenomenon.

NETHERLANDS
The properties needed for aircraft tire treads are significantly different to the ones required for passenger car or truck tires, for which improvements mainly focus on a better balance of rolling resistance, wet skid resistance and wear resistance. Aircraft tires experience severe operation conditions during service: the temperature can reach the critical temperature of polymers, thus accelerating tread wear and aging. To reduce this temperature degradation, the material should have a low hysteresis. This presentation will focus on the influence of the type of filler and will include adjustment of the processing conditions for optimization of aircraft-tire-related properties.

Is the Velcro concept feasible for an alternative silica/polymer coupling?

Anke Blume
Full professor
University of Twente
NETHERLANDS
A new concept for an alternative silica/polymer coupling system was introduced to the tire industry in 2019 to overcome the disadvantages of the current system. Currently, if the relatively stiff covalent sulfur bridge of the silica/silane/polymer connection is broken, there is no possibility to reconnect. As a consequence, a completely different coupling concept was considered, mimicking the Velcro system known from nature. The tangled and cross-linked rubber macromolecules act as molecular loops, and relatively long elastomer brushes grafted on the silica surface act as molecular hooks. The in-rubber properties will be presented to show the efficiency of this new system.

Knowledge about load-dependent fatigue crack growth (FCG) behavior is vital to estimate the lifetime of tires. Therefore most companies are using dynamic testing appliances to load rubber samples by observing the FCG. Historically, it has been necessary to use highly educated staff to perform the analysis. In this work, we explain how a methodology can be successfully implemented to control the FCG analysis fully automatically. Once the samples are fixed, the measurement is started and works in a self-controlled way until the end. This makes research and development more efficient.

Promoting steel cord adhesion – replacing cobalt salts with hexamethylene bis-Bunte salts

Jeffrey Lin
Associate scientist
Eastman Chemical Company
USA
Replacing cobalt salt in a tire’s steel cord compound with hexamethylene bis-Bunte salt (DHTS) gives comparable steel cord adhesion (SCA) relative to the cobalt salt-containing compound. Based on results, good SCA can be attained with reduced cobalt salts and is generally within the experimental error with a cobalt-neodecanoate-containing compound, and slightly better in the case of steam and salt water. Also, brass-to-rubber interfaces were studied using x-ray photoelectron spectroscopy (XPS), with data indicating the presence of DHTS and in-situ-generated reducing agent. This suggests the Cu and Zn oxidation state can be modulated, leading to improved adhesion.

Systematic analysis of service-failed tires is of paramount importance to understand the root causes of the tire failure and take appropriate corrective measures. During the investigation it often becomes extremely challenging to hypothesize the sequence of events that might have occurred prior to the ultimate failure, and it becomes difficult to pin down the root cause of failure. The characteristic nature of ruptures at the fracture point of steel cord filaments is linked to specific causes. The present study is focused on forensic analysis of service-failed tires where steel cords were eventually fractured, to identify the root causes of failure.

Cord adhesion without cobalt and resorcinol and with less zinc

Roberto Blanco Trillo
Business development manager
Allnex
GERMANY
Resorcinol replacements are commonly used in tire compounds to improve adhesion between rubber matrix and the surface of metal inserts while attaining a significant reduction in workplace exposure and no fuming by resorcinol. The next step to reduce environmental concerns is to eliminate not only resorcinol but also cobalt salts by using a zinc-functionalized resin in a masterbatch. The vulcanization speed is attained with significantly reduced zinc levels, and the use of cobalt salts is completely avoided. This approach provides high cord adhesion without cobalt or resorcinol while reducing zinc – a triple green solution.

Among all specimen geometries for rubber frictional measurements, a wheel shape sample is of great interest. In the first step, the static contact areas and pressures of Grosch wheels on various surface roughness were measured and compared with those of the corresponding real tires. The effect of the in-rubber properties on the contact area was investigated to enhance the insight into the tire contact patch.

Will Martian rovers ever run on rubber tires?

Dr Rafal Anyszka
Researcher

Designing rubber materials that could withstand harsh Martian conditions is a challenging task. Space radiation severely damages the chemical structure of rubber macromolecules, and the low average temperature limits the types of applicable rubbers only to those exhibiting very low glass transition temperatures. However, the advantages provided by the unique elastic and dumping properties of rubber have become more attractive in view of the Curiosity rover wheel damage that occurred during Mars exploration, which was due to the poor elastic performance of aluminum used for the tires' construction. This triggers the question: is it technologically feasible to develop rubber compounds for Martian rover tires?

A review of recent developments in tire durability simulation

Dr William Mars
President
Endurica LLC
USA
Tire durability simulation methods have developed rapidly during the last decade to overcome several barriers. Critical plane analysis has solved the problem of how to compute the impacts of multiaxial stress and deformation mode on fatigue. Total and incremental fatigue solvers now enable durability analyses to be solved for a single operating condition, for multi-step testing schedules or for residual fatigue life. Non-linear material behaviors such as strain crystallization and temperature dependence can be specified and taken into account. The methods are applied to show how development and regulatory tire durability tests can now be simulated.

Measuring friction to predict tire behavior on different road surfaces

Alexander O'Neill
Research engineer
University of Surrey/Jaguar Land Rover
UK
Most tire models used in vehicle dynamics simulations are parameterized with data obtained on a flat-track, where the tire is commonly driven on sandpaper. The resultant models are typically inaccurate at higher slips, where conditions are dominated by the rubber-road friction characteristics. To improve such tire models, this paper explores the use of tread rubber friction measurements obtained with a purpose-built rubber friction measurement system. Friction measurements were performed under controlled conditions and incorporated into a brush-type tire model. Preliminary results indicate the benefits and potential of detailed knowledge on the frictional behavior for accurately modeling tire forces and moments.

Numerical evaluation of tire heat generation and temperature distribution using SSHT

Rajesh Nagose
Senior manager/solution consultant
Dassault Systèmes

Tire performance highly depends on temperature rise during operations because rubber material properties are highly temperature and frequency dependent. Hysteresis loss or viscous energy dissipation is the main contributor to the tire heating as the tires are subject to cyclic loading. This work aims to evaluate tire heat generation and temperature distribution using the steady-state heat transfer (SSHT) solution. The parallel rheological framework (PRF) material model captures the viscous energy dissipation and this output is used to evaluate heat sources for thermal simulation. Heat transfer analysis is performed using this heat source and surface film coefficients boundary conditions.

Modeling of hyperelastic material (rubber-like) with various material models has always excited the research community. Selection of a material model has a considerable impact on the simulation output of a component. This selection depends on the availability of an experimental test setup. Uniaxial test setup being the most common across industries, the Yeoh model has been the engineers’ choice as it represents other modes of deformation well, even with uniaxial test data. Similarly, an extended tube model also gives Yeoh-like benefits with a better fit between theoretical and experimental data.

New Exxpro specialty elastomer 3563 with superior impermeability for tires

Dr Sunny Jacob
Elastomer technology advisor
ExxonMobil Chemical
USA
Isobutylene elastomers are of great commercial importance in tire applications due to their notable low gas permeability properties attributed to their efficient molecular packing. Brominated isobutylene-co-para-methylstyrene (BIMSM) elastomers are a special class of isobutylene elastomers synthesized by random cationic polymerization of isobutylene and p-methylstyrene (pMS), followed by a selective bromination of the methyl group of the para-methylstyrene units. BIMSM elastomer, commercially known as Exxpro specialty elastomer, exhibits superior heat resistance and aging properties, and is much more resistant to chemicals and ozone than butyl or halobutyl polymers due to its fully saturated backbone structure. This paper will present the chemistry and application aspects of the newly developed BIMSM elastomer, Exxpro specialty elastomer 3563, to meet the growing market demands and requirements for low maintenance, low inflation pressure loss rate (IPLR) tires and tires for connected autonomous shared electric vehicles.

However, due to extreme temperatures and repeated flexing cycles, the lifetime of a bladder is limited. One reason is an unwanted migration of traditional plasticizers out of the article, which is leading to stiffness issues. The presentation offers new plasticizer types for an extended service life of bladders. Finally, a cost advantage is achieved.

For all-seasons/winter tire development for vehicle OEMs based in Europe, a snow testing session in Scandinavia is needed. Winter testing is possible and economically convenient only in northern Europe in a small timeframe. Therefore, winter tire development is not achievable outside these boundary conditions.

Nevertheless, several factors affect tire performance during coast-down and increase the variability of the results, and not all of them are related to the tire rolling resistance. This study aims at understanding the conditions under which the tire performs the best and provides the lowest resistance, and how this can be translated into a more effective deceleration leading to emissions benefits.

A methodology has been developed to simulate the tire static behavior and estimate its constituent hyperelasticities based on the measured tire responses (radial, longitudinal and lateral stiffness) for the applied static loads. First, a simplified tire numerical model with standard rubber material properties is modeled that can substantively predict the necessary tire static responses. These responses are compared against the physical tire responses that are measured using a kinematic and compliance (K&C) test rig. Finally, a DoE and an optimization process are performed by sampling the rubber hyperelasticies to simulate the FE model and match the tire static test responses precisely.

Velocity measurements of the water flow in tire grooves

Damien Cabut
PhD student
Ecole Centrale de Lyon
FRANCE
Hydroplaning occurs when a tire encounters more water than it can scatter. Hydrodynamic pressure builds up in front of the tire and induces loss of surface friction, which diminishes the available braking force that it can generate in an emergency braking, for example. Therefore, it is crucial for tire designers to optimize tread designs to ensure the best water evacuation without compromising any other performance. In this work, a measurement method based on particle image velocimetry is proposed to measure the velocity field in the grooves of a worn tire rolling through a water puddle.

Real snow roads are exposed to changing conditions such as unstable temperatures or variable snow conditions. These changes have a significant influence on the snow friction of a tire tread block. We intend to quantify these effects experimentally by means of targeted parameter studies. For the parameter studies, we investigate the behavior of a tread block on a linear rolling test rig with variable slip ratios on snow roads. The results show that the temperature has a considerable influence on the snow friction of a tread block. The phenomenon can be explained physically by the temperature-dependent strength of the snow.

The system measures actual tire tread depth, which is more accurate than inferring tread depth from other vehicle data.

ANEW tires – Angular Navigation Early Warning tires

Rajesh Gaddipati
Solution architect
Fujitsu Consulting India Pvt Ltd
INDIA
The aim of this project is to help tire manufacturing companies to design a set of sustainable solutions to ward off various road mishaps, to output an intercept to identify an overtaking vehicle, and to signal a quick estimate of all forms of rough terrains (wrongly designed angle of banks, misconstrued roads) to keep vehicles (heavy ones in particular) from fatal toppling. In this pursuit, inside the tire we will affix well-calibrated, cost-effective, non-cumbersome mechanical semi-micro tools such as a magnetometer (compass) and gyroscope, which will work together to help input to an edge computing instrument to output a quick intercept to the driver.

Tire tread accelerations and sound pressures measured when driving on roads

Alan Bennetts
Director
Bay Systems
UK
Tires with embedded sensors should improve handling and safety but only if their signals can be interpreted correctly and change enacted quickly. To try and understand what might be possible, we have installed instrumentation inside the tire to gather high-quality signals. The data has been gathered on the public highway for a range of tires and road surfaces. The results we have obtained demonstrate that data from the tire/road interface does indeed contain a lot of information that can differentiate surfaces. But at what level of computational effort does this become cost-effective?

RFID on OTR tires from production to the field

Jos Uijlenbroek
Vice president RFID tire solutions
Fineline Technologies
NETHERLANDS
Vulcanized RFID barcode bead labels are becoming common for the identification of tires in general, but especially for off-the-road (OTR) tires. The production methodology makes it difficult to apply identification methods before and/or after vulcanization. This presentation gives an overview of the use of RFID within the tire production processes and the digitization of manufacturing logistics in the age of Industry 4.0; the use of RFID bead labels to track and trace tires, especially OTR tires, from production processes all the way to the customer location.

Bio-refinery alternative to fossil and vegetable oils in winter tires

Dr Fabio Bacchelli
Technical manager
Versalis
ITALY
Tire tread compositions containing high-molecular-weight sSBR might be desired for traction on wet road surfaces. For cold-weather service, a current challenge is to reduce the cured stiffness of the rubber compositions, having a lower storage modulus at about -20°C, while maintaining wet traction. Since the need to preserve the environment has become a major driver for the development of tire tread compounds, many attempts have been made to introduce vegetable oils to match performance, processability and sustainability. An important LCA improvement can be achieved using a specifically designed bio-refinery vegetable derivative obtained through a bio-to-bio conversion technology.

Sustainable fillers (rCB)

Fredrik Olofsson
Sales manager
Scandinavian Enviro Systems AB
SWEDEN
The ever-growing interest in sustainable technology and the increasingly decisive questions about how greenhouse gas emissions should be reduced mean that there is increasing interest in Scandinavian Enviro Systems' unique technology in the tire and rubber industry. Sustainable fillers and TPO with high bio content are now really starting to be introduced to the market based on Enviro's technology. The question now is more linked to capacity than if the 'new' products works. The presentation will describe the company's progress so far, including a brief technology presentation, an introduction to sustainable filler and TPO plus rCB in the tire/rubber industry, capacity/plant establishment and plans for the future.

Achieving a tire circular economy using high-performance sustainable material

Sonia Megert
Chief operating officer
Tyre Recycling Solutions
SWITZERLAND
Although material recycling of tire rubber could play a significant role in the treatment of end-of-life tires and decrease the environmental footprint of tires throughout their lifecycle, the amount of tire rubber being truly recycled is still extremely limited. The key issues in creating a truly circular economy are to understand the materials science and to guarantee constant and high quality of recycled products. This paper describes the physics of incorporating rubber waterjet powder into SBR-based compounds. It also looks at strategies to ensure the global availability of high-performance sustainable material.

Dr Fabian Grunert
Postdoc
University of Twente
NETHERLANDS
The automotive sector is facing continuous changes that also directly affect the tire industry. In particular, regulations regarding a reduction in CO2 emissions related to fuel consumption and rolling resistance force continuous improvement in tire performance. To be able to meet the future requirements of the automotive industry and keep the knowledge of employees up to date, the European DRIVES project was initiated to offer new requalification possibilities. One piece of training being developed is to become a rubber technologist. In addition to the basics of rubber technology, this training includes innovative green technologies considering bio-based polymers, fillers and additives, and recycling possibilities.
