The main objective of the present work is to develop micro-modelling of elastic modulus of graphene nanoplates (GnPs) reinforced mixture of epoxy resin and PVDF polymer materials. The weight percentage variation of graphene nanoplates are incorporated in the mixture ratio 10:1 of epoxy resin and PVDF polymer materials for the measurement of elastic modulus with the variation of weight percentage of graphene nanoplates under tension and compression. Results indicate that the elastic modulus under tension and compression increases with the increase of weight percentage of graphene nanoplates in the mixture of epoxy resin and PVDF polymer matrix due to inhancement of mechanical properties of mixed PVDF and Epoxy resin polymer matrix.
