Grafen nanoplatelet takviyeli epoksi kompozitlerin mekanik özellikleri ve aşınma davranışı üzerinde takviye oranının etkisi

Abstract

New features are gained to the enhanced characteristic of composites with the addition of nanoscale particles. Graphene has an important place among nanoparticle reinforcing elements due to its two-dimensional structure and high strength. In this study, tribological behaviour and mechanical properties of the nano particle reinforced composite material investigated. The amount of nano particle reinforcement on the mechanical and wear behavior was investigated. Nanoparticles were incorporated into the non-reinforced sample at varying weight ratios, ranging from 0.1% to 0.5%. The findings indicated that the inclusion of graphene nanoparticles into the epoxy matrix material enhances the mechanical properties of the specimens across all reinforcement ratios.The failure load of the neat epoxy samples was determined as 415.94 N and the modulus of elasticity as 2.4 GPa. The best mechanical results in graphene reinforced composites were obtained in 0.2% reinforced composites, and the failure load and elasticity modulus values were found as 903.13 N and 4.46 GPa, respectively. Furthermore, the tribological performance of the specimens was examined under dry sliding conditions. The worn surfaces were examined using SEM. The incorporation of graphene reinforcement has been observed to positively impact the wear resistance of the epoxy matrix material.
