Influence of Thermal Aging in Oil on the Friction and …

An experimental study on the influence of thermal aging on the friction and wear properties of a nitrile butadiene rubber (NBR)–steel pair was carried out. Rubber specimens were aged in hydraulic oil at 60 °C and 90 °C for 0–70 days. The Shore hardness, Young’s modulus, rebound resilience, and other mechanical properties were measured. The friction coefficient and wear

Complex Modulus - an overview | ScienceDirect Topics

Conventional ageing tests and on-site ageing lead to a shift of the curves towards lower phase angle, especially in the low modulus and high angle region (see Figs 12.8 and 12.9, respectively). It has to be noted that the high modulus region seems not to be affected by laboratory ageing procedures but appears to be affected by field ageing.
