| Abstract | ||
| In the present paper, changes in the residual stress of carbon/epoxy laminated composites as a result of adding graphene nanoparticles (GNPs) content were studied theoretically and experimentally. Three dissimilar weight fractions of GNPs, i.e., 0.1%, 0.25% and 0.5%, were added into an epoxy matrix. Unidirectional carbon fibers (CFs) were used as reinforcement to fabricate cross-ply laminated composites. Mechanical and thermal properties of the GNP/epoxy nanocomposites were then characterized via tensile tests as well as thermomechanical analysis (TMA). Based on experimental observations, adding even small fractions of GNP to epoxy matrix caused to decrease in the coefficient of thermal expansion (CTE) significantly while the epoxy resin Young | ||
