Abstract:
Fiber reinforced polymer composites (FRPCs) have been widely known for their high strength and better wear resistance in dry sliding condition mainly related to adhesion transfer or fatigue. However, the way FRPCs behaves under abrasion wear situation needs proper investigation. Hence in this study, three-body abrasion wear behaviour of Neat Nylon66 (NN), short-glass fiber (SGF) reinforced Nylon66 (SGF/NN) composites and talc filled SGF/NN (T-SGF/NN) hybrid composites were investigated. Talc fillers were varied from 2 to 8 wt.% at a step of 2 wt.% and designated as 2T-SGF/NN, 4T-SGF/NN, 6T-SGF/NN, and 8T-SGF/NN hybrid composites. These composites were fabricated by melt blending technique using twin screw extrusion and injection molding process. Three body abrasion wear test was performed using rubber wheel abrasion tester in accordance at ASTM G-65 for different loading conditions (10, 15 and 20 N) and abrading distances (500, 750, and 1000 m). Results revealed that wear loss of all the composites increased with increase in the applied load and abrading distance which is attributed to penetration of abrasive particles, micro-cutting and fiber-matrix debonding. However, specific wear rate (SWR) decreased with respect to increase in abrading distance due to the formation of protective tribo-layer that stabilizes wear. In contrast, SWR increased with increasing in applied load because severe contact stress and intensified material removal. Worn surface of the talc filled SGF/NN composites were examined field emission scanning electron microscope (FESEM). Average surface roughness and dept of wear were measured using 3D optical profilometer.
