Nanocomposite graphene oxide/epoxy was fabricated successfully in this research. Graphene oxide (GO) has been synthesised by using modified Hummer method. SEM picture showed that GO had been exfoliated clearly after chemical oxidation in concentrated H2SO4 acid. The oxygen functional groups that could be seen on the FTIR spectra, were attached onto GO surface. XRD spectroscopy showed that the space among the layers of GO increased from 0.34 nm to 0.78 nm after oxidation, which can be explained by the insert of oxygen functional group. BET results provided information of specified surface areas, porous volume and article diameter of the product. GO has a medium porous diameter. It is also shown that the mechanical properties of the fabricated product improved significantly with the use of GO as compared to neat epoxynanocomposite. The optimum amount of GO in GO/epoxy was 0.5% of weight.
