Graphite nanoplatelet (GNP) which is graphitic nanofiller made up of stacked two-dimensional graphene sheets presents special physical and chemical properties which hold great promise in many applications. A brief review of the literature reveals that incorporating these nanomaterials into a polymer matrix effectively improves their properties which do not usually follow the rules of composites in the micro. The mechanical properties naturally depend on the geometry and properties of nanofillers as well as load transferring between nanofillers and matrix. Because of heavy atomistic simulation on the nanostructures, many researchers have been interested in the connection between nanostructures and the continuum mechanics. This paper is in such a category which shows the effective mechanical properties of epoxy-graphite nanoplatelet composites by focusing on asymptotic homogenization method during the multiscale technique.
