Comparison of the tribological and mechanical performance for nano and micro filler epoxy composites

In this investigation, the tribological and mechanical performance of 10 wt.-% filled nano and micro epoxy composites were studied and compared. Nano fillers are Al2O3, TiO2 and clay and micro fillers are Al2O3, TiO2 and fly ash. Mechanical and wear tests were carried out. Wear tests were performed on pin-on-disc arrangement. Test conditions were 5, 10, 15 N applied load values, sliding speed of 0.8 m x s(-1), 2000 m sliding distance under dry atmospheric conditions. The results show that the mechanical and tribological performance of micro filler filled epoxy composites are better than those of the nano filler filled composites
