Impact of Thickness on Rubber Aging Life

Article Preview

Abstract:

Rubber products of different thickness have a significant difference of aging degree in mechanical properties due to varied environmental impact from surface to center. Previous study of performance degradation and life prediction methods did not pay enough attention to this problem. In this paper, a quantitative analysis is conducted, and a relationship between properties of different depth (given by a 40 years indoor natural aging experiment) and material overall properties is built to observe mechanical properties changing and evaluate aging life of different thickness of rubber. The result shows an obvious difference in mechanical properties and aging life, which seems should be considered when conduct an aging experiment and life evaluation.
