In this study, effect of glycidylisobutyl oligomeric silsesquioxane (G-POSS) and 1.1'-carbonyl-bis-caprolactam (CBC) (1 wt.%) on the friction and wear performance of polyamide 6 (PA6) and short glass fiber (SGF) (10 and 20 wt.%) reinforced PA6 composites were investigated. Adhesive wear tests were carried out by using a tribometer in block-on-ring configuration (ASTM G77), in sliding conditions, without lubricants and in air. Tests were carried out at sliding speed of 1.6 m/s (511 rpm) and applied load values of 25, 50 and 75 N. Wear rate was calculated using weight loss per unit sliding distance. The results showed that, the friction force increases with the increasing load. It was found that the wear resistance of PA6 improved considerably after doping with CBC.
