Abstract: Nylon (N), Glass-filled nylon (GFN) composites and hybrid graphene oxide blended GFN (GO-GFN) nanocomposites plates were prepared by blending and subsequent injection molding process. Mechanical tests were conducted to study the tensile property, flexural property and hardness of nylon, GFN and GO-GFN system. The fabricated plates were subjected to abrasive wear testing in Pin-on-disc tribometer. The pin used is aluminium oxide (Al2O3) ceramic tool. The coefficient of friction, frictional force and loading variations were observed and studied to analyze the susceptibility of nylon, GFN and GO-GFN nanopolymer composites for abrasive wear conditions. This experimental study confirmed the enhancement in the abrasive wear resistance behavior of GO-GFN hybrid nanocomposites.
