Comparative Investigations on the Mechanical and Tribological Properties of Glass Fibre Reinforced Thermoplastic and Blended Graphene-Oxide Hybrid Thermoplastic Nanocomposites

Abstract:

Glass filled nylon composites (GFN) and hybrid graphene oxide reinforced glass filled Nylon nanocomposites (GO-GFN) are prepared by blending the required base materials in injection molding machine at processing temperature of 275°C. The specimens prepared are subjected to various mechanical property tests to reveal their hardness, tensile strength and flexural strength. The wear discs of GFN and GO-GFN composites as per ASTM standard are injection molded to analyze the tribological properties using pin on disc tribometer. The pin used is EN 8 Tool steel. The Coefficient of friction for the GFN composites for the wear load of 10 N is 0.28. Addition of 0.003 wt% GO to the GFN system has decreased the coefficient of friction significantly to the value of 0.12. The decrease in C.O.F was correlated with the adhesion film formation in the pin surface. This work confirms the improvement in wear resistance of GO-GFN system which is attributed by the presence of graphene oxide only.
