Characterization of Wear Resistance of Silica-Styrene-Butadiene Rubber Filled Hybrid Composites

Composite materials are made from two or more constituent materials with significantly different physical or chemical properties which remain separate and distinct on a macroscopic level within the finished structure. In the present work a silica-styrene-butadiene rubber hybrid composite material is developed with 1 and 2 wt% of nano sized silica particle and 0.25 to 1.5 wt% of styrene-butadiene rubber mixed in resin. About 75% of wear reduction is found due to addition of silica particle, whereas addition of styrene-butadiene rubber has insignificant effect on the wear rate. However, it slightly increases the wear rate as compared to silica filled epoxy composite. Hybrid composites with higher silica content exhibit higher hardness.？ A good liner correlation between wear rate and hardness exists with probability p <= 0.01？？ and correlation coefficient R> 0.8
