Abstract

In this paper, the mechanical behavior of the GRAPHENE OXIDE (GO) /epoxy NANOCOMPOSITEs has been investigated under different STRAIN RATEs. To reach this goal, GO nano sheets were synthesized through Hummers method (a chemical method) and then GO/epoxy NANOCOMPOSITE was prepared using the solution-based method. Standard test specimens were made from NANOCOMPOSITE. In order to study the static and dynamic behavior of material, the static pressure test and the split pressure Hopkinson bar test were performed on the specimens, respectively. The results showed that the stiffness and the strength of EPOXY increase by adding GO to it. It was found that the behavior of EPOXY is dependent on a STRAIN RATE so intense that its dynamic strength is about 50% more than the static one. Furthermore, the effect of GO at low STRAIN RATEs is more than high STRAIN RATEs such that adding 0.3% weight ratio of GO increases the strength of EPOXY by nearly 20% and 5% in 0.01s-1 and 1100 s-1 of STRAIN RATEs, respectively. In addition, the comparison of Scanning Electron Microscopy (SEM) images from the fracture surfaces of neat EPOXY and its composite showed that the surface toughness of NANOCOMPOSITE is more than that of EPOXY.
