| Abstract | Graphene nanoplatelets (GNPs) are a novel nanofillers including single or multilayers of a graphite plane which possesses exceptional functionalities, high mechanical strength (1 TPa in Young's modulus and 130GPa in ultimate strength), and chemical stability, for the following reasons: their abundance in nature and thus their cost effectiveness and their extremely highspecific surface area, which carries high levels of transferring stress across interface and provides higher reinforcement than other carbon materials. Because of their high absolute strength, large surface area and costeffectiveness, graphene nanoplatelets (GNPs) have high potential for improving the material properties of polymerbased composites. In this study, the graphene nanoplatelets (GNPs) modified with maleic acid (MA) were used to reinforce epoxy resin to prepare the GNPs/epoxy nanocomposite and to investigate their mechanical properties. The mechanical properties of GNPs/epoxy nanocomposite, such as ultimate tensile properties and impact strength were investigated. Significant improvement in the mechanical properties of nanocomposites containing different proportions of GNPs were increased over that of neat epoxy resin. The fracture surfaces of the neat epoxy composites (without adding GNPs) and the GNPs/epoxy nanocomposites were comparatively examined using Scanning electron microscope (SEM). The images showed that nanofillers exhibited higher solubility and compatibility in epoxy matrix. Therefore, embedding GNPs can restrain creviced growth in the GNPs/epoxy nanocomposites and prevent the expansion of these cracks. |
