The effects of geometrical parameters on mechanical properties of graphite-vinylester nanocomposites and their constituents
(matrix, reinforcement and interface) are studied using molecular dynamics (MD) simulations. Young’s modulii of 1.3 TPa and
1.16 TPa are obtained for graphene layer and for graphite layers respectively. Interfacial shear strength resulting from the
molecular dynamic (MD) simulations for graphene-vinylester is found to be 256 MPa compared to 126 MPa for graphitevinylester.
MD simulations prove that exfoliation improves mechanical properties of graphite nanoplatelet vinylester
nanocomposites. Also, the effects of bromination on the mechanical properties of vinylester and interfacial strength of the
graphene–brominated vinylester nanocomposites are investigated. MD simulation revealed that, although there is minimal effect
of bromination on mechanical properties of pure vinylester, bromination tends to enhance interfacial shear strength between
graphite–brominated vinylester/graphene-brominated vinylester in a considerable magnitude.
