Getting a quick read on rubber thermal degradation
Traditional laboratory tests to determine the thermal aging of rubber used for tires consist of performing standard tests after aging, and the aging process is typically carried out over a period of hours to months, which is very time-consuming. Therefore, this study proposes a new way of quantifying the thermal degradation process that directly identifies the embrittlement or softening/hardening of rubber which are consequences of aging phenomena. A physical compliance parameter will be introduced to quantify the susceptibility of rubber to cracking due to thermal aging, where the whole analysis only takes up to two hours.
