In the present research, MD simulations have been employed to study the mechanical
properties of epoxy DGEBA with and without reinforcement of CNT. A triangular cross link
rigid structure has been created using Material Studio (MS) software. An amorphous cell has
been created which is a reprensentative composite. All the simulations have been carried out
using Forcite module of Material Studio. Mechanical properties with and without reinforcement
of CNT have been obtained. It has been found that at room temperature, Young.s modulus of
DGEBA-DETDA composite is 2.429 GPa while after reinforcement of CNT, Young.s modulus
increased to 13.27 GPa. The MD simulation results indicate that the Young.s modulus of the
reinforced composites and the epoxy matrix decrease with increase in strain rate (from 0.0 to
0.1). MD simulation results show that at any given strain rate, CNT reinforced epoxy composite
is 5 times stiffer than the pure epoxy matrix.
