Graphene is a two-dimensional hexagonal type of carbon allotropes in the form of a
sheet. It is a one atom thick sheet of carbon atoms, which has extraordinary thermal,
mechanical, electronic and electrical properties. In the present research, a molecular dynamic
study has been done to investigate the mechanical properties of graphene reinforced epoxy
nanocomposite. A single layer of graphene sheet has been randomly reinforced into the epoxy
matrix at 5%, 10%, 15% and 20% weight percentages. A dense amorphous cell is created
using the Forcite module of Material Studio software and simulation is performed. Young's
modulus is predicted at varying strain rate from 0-1. Results have revealed that Young's
modulus increases with increase in reinforcement quantity. Moreover, graphene reinforced
epoxy nanocomposite exhibits better properties than CNT reinforced nanocomposites.
