Abstract
The influence of fatigue on adhesion of cord/rubber composites was investigated through H-pull tests. Fatigue was found to promote sulfur diffusion from rubber to RFL and induce modulus homogenizing. Higher frequency caused decrease in fatigue life due to self-heating, but the effect was negligible under low displacement amplitude. Longer fatigue life was achieved at higher R ratio, but an exceptional increase in fatigue life was found at the highest R ratio. A universal CLD model was established for predicting fatigue life. Results of model verification revealed a critical R ratio, above which H-pull test no longer accurately evaluated dynamic adhesion.
