A Study on the Fractal Behavior of Worn Surfaces of Zinc Oxide Whisker/Natural Rubber-styrene Butadiene Rubber-butadiene Rubber Composites

摘要

The wear resistance of zinc oxide whisker (ZnOw)atural rubber-styrene butadiene rubber-butadiene(NR-SBR-BR) composites has been studied. The result showed that ZnOw modified by coupling agent has a good effect on improving wear resistance of the rubber composites. The further investigation shows that the worn surfaces of the composites of ZnOw/NR-SBR-BR appear distinct character of fractal, and the values of both the fractal dimension and the abrasion loss decrease synchronously as the increasing of ZnOw content in the composites.
