Effects of Abrader Roughness on Particle Size of Worn Rubber Compoundsin Fatigue Wear

Rubber compounds are prone to wear when sliding on uneven or rough surfaces. Rubber abrasion onreal rough surfaces is an important issue in many practical applications such as tire tread and shoesole engineering. However, the interaction of rubber with rough surfaces is still not fully understooddespite the existence of extensive theories and experiments. In the wear mechanism, the roughnessof the abrasive surface has an important effect on the wear behaviour of the rubber, because with thechange of roughness, many factors such as the friction coefficient of rubber-surface and surfacetensions, which are involved in the creation of cracks and material loss of the rubber, change. Thisresearch is dedicated to investigating the effect of surface roughness on the formation of wornparticles in fatigue wear of tire tread compounds. The size and size distribution of the worn rubberparticles using an Akron abrader was measured and analysed. The correlation between surfaceroughness of grinding wheels and average size of the rubber worn particles can be used in themodelling of rubber abradability and simulation of tire wear.
