Abstract
By using a special fatigue testing system for cord/rubber composites, the fatigue damage accumulation characteristics of rubber composites under periodic loading were assessed, and the fatigue life prediction equations were given in the case of polyester/rubber composites and rayon/rubber composites. The effect of frequency on the fatigue life of rubber composites and the variation of surface temperature of rubber composites during fatigue process were also examined. The results indicate that high heat is followed with fatigue process of rubber composites. This is the main difference between rubber composites and brittle composites. The surface temperature canbe reached to 100°C for polyester/rubber composites and 40°C for rayon/rubber composites during fatigue experi- ments. The effect of frequency on the fatigue life of different rubber composites is different. The fa- tigue life of polyester/rubber composites with high viscoelasticity are increased when frequency is increased and the fatigue life of rayon/rubber composites with low viscoelasticity vary little when frequency ischanged.
