摘要：The increase in the styrene content in styrene-butadiene rubber (SBR) can improve the abrasion performance and cutting resistance of rubber, which has received attention in the tire industry. The fatigue performance is the main evaluation index of rubber materials applied to tires. In this study, the effect of the styrene content and its interaction with carbon black (CB) on the dynamic fatigue performance and mechanism of SBR were investigated. The results indicated that the dynamic fatigue life of the rubber composite materials was prolonged with increasing styrene content; furthermore, it showed a trend of increasing and then decreasing with increasing CB content. At a certain CB content, styrene and CB displayed a synergistic effect on improving the dynamic fatigue life of the composite materials. The dynamic fatigue performance of SBR40/CB20 was the best. The expansion of the fatigue cracks followed the secondary cracking mechanism, which consumed a large amount of strain energy and slowed the development of the main crack. However, when the CB content exceeded 40 phr, the mechanism transformed to main crack self-propagation and the fatigue life decreased.
