Investigation of thermal aging effects on the fatigue design of automotive anti-vibration parts

Résumé

Automotive parts made out rubber-like materials are usually massive and aging therefore leads to heterogeneous properties, possibly induced by several mechanisms due to the availability, or not, of oxygen in the part’s bulk. To better understand the effects of oxygen in the degradation process, this paper aims at studying the aging of a rubber material (conventional vulcanization system) in aerobic (with oxygen) and anaerobic (without oxygen) conditions for a wide range of temperatures relevant for underhood applications. To realize aging under anaerobic conditions, a protocol was implemented, tested and approved. The consequences on the mechanical behavior are analyzed throughout fatigue campaigns results (failure surfaces and loss of fatigue properties).
