Abstract
This study aims to investigate the effect of the graphene nanoplatelet (GNP) at different contents on the mechanical, tribological, and thermal properties of epoxy-based phenolic resin (EPhR) nanocomposites. The sliding wear tests of the nanocomposites were performed using ball-on-disc tester at room temperature under a constant load and sliding speed in ambient air. The friction coefficient and wear rate were obtained for 0.5 wt% GNPs addition 0.14 and 510-7 mm3/Nm with increases of 30% and 74%, respectively, compared to the neat EPhR. The tensile strength and modulus of elasticity were found for the 1.0 wt% GNPs addition 74.0 MPa and 6.2 GPa, respectively. Moreover, the composites were characterized using SEM and TGA. The GNP reinforced composites showed an increase of 8.0–59.2% in thermal stability data when compared to the neat EPhR. The results indicate that GNP content and dispersion in resin have a substantial effect on thermal stability, mechanical and tribological performance of composites.
