Effect of graphene nanoplatelets on the fracture toughness of nanocomposites based on epoxy resin

One of the important properties of thermoset resins is their fracture toughness depends on several factors. Various fillers are used to improve this property. In this study, the effect of graphene nanoplatelets on toughness of nanocomposites based on epoxy were investigated. Due to the properties of graphene, especially its high specific surface area, to improve the fracture toughness of the composite was added and toughening mechanisms were studied. With the addition of various amounts of graphene, it is optimum to achieve maximum fracture toughness was obtained With the addition of various amounts of graphene, it is optimum to achieve maximum fracture toughness was obtained. With the addition of 0.4 wt% graphene, the stress intensity factor of nanocomposites increased 136 percent compared to the pure epoxy
