Effect of Graphene on Mechanical Performance of Pin-Loaded Circular Hole in Laminated Composites

An analytical modeling was performed to investigate the effect of Nano filler on the mechanical performance of carbon fiber reinforced composite joints using the characteristic curve method. The joints were prepared from carbon fiber reinforced laminated plates with and without graphene nanoplatelet (GNP) and the characteristic dimensions used to determine the characteristic curve were evaluated from stress functions without experimental tests. The load-bearing capacity of the joints were carried out using different coefficient of friction and Yamada-Sun failure criterion along the characteristic curve. The evaluated results showed that the infusion of graphene nanoplatelet into the epoxy matrix of fiber reinforced composite plate increases the failure load of the composite joints.
