The dynamic ageing of vulcanizates - DMA method vs. crack growth rate
Original language description
Thus the aim of this study is to determine the influence of thermal aging processes in air environment and in the wide temperature range, which closely resembles the tire application environment in the field. In the present study, Fatigue Crack Growth (FCG) behavior of varied industrial blends directly suitable for treads applied in agricultural tires, have been investigated. A new parameter based on loss compliance factor has been identified for describing the embrittlement or softening/hardening of aged rubber matrix by using of dynamic mechanical analysis (DMA). These evaluated data have been compared with the fatigue crack growth parameters observed by the using of a dynamic testing machine, Tear and Fatigue Analyzer (TFA) simulating the loading conditions of tire. The correlation between loss compliance parameter and fatigue crack growth data has been evaluated and explained. The loss compliance factor has been determined to be a suitable parameter predicting the behaviour of rubber materials affected by higher temperature.
