摘要
The fracture characteristics of graphene nano-platelets(GNP)in epoxy composite under high strain loadings were investigated using impact test at room temperature.The energy required to create a new surface was measured with load cell and the accompanied plain strain fracture toughness was calculated.The investigation covered the effect of the amount of graphene in graphene/epoxy composite material system on the fracture behavior of the material.The results showed that both the manufacturing and experimental procedures developed were excellent to quickly and precisely characterize the response of GNP/epoxy composite to impact loadings.Furthermore,the results showed clear dependencies of the material response on the amount of GNP in epoxy.
