原始语种摘要: The paper discusses about the wear and micro hardness behavior of Graphene Decorated with Graphene Quantum Dots (G-D-GQD) reinforced epoxy composites. The samples were prepared by open mold casting method by adding 0.25–1 wt. % (in an interval of 0.25%) of GDGQD and evaluated on a reciprocating wear tester configuration for wear and coefficient of friction properties. The micro-hardness testing of the G-D-GQD particles embedded epoxy composites has been performed and the hardness value results were compared with neat epoxy to find the improvement in hardness. Significant improvements in the hardness and wear resistance of the epoxy nanocomposites was obtained by the embedding of G-DGQD fillers, which is due to the efficient bonding of GDGQD filler with the epoxy matrix.
