Abstract

Carbon nanotubes (CNTs) demonstrate unusually high stiffness, strength and resilience, and are therefore an ideal reinforcing material for Nano composites. However, much work has to be done before the potentials of CNT-based composites can be fully realized. Evaluating the effective material properties of such Nano scale materials is a very difficult task. Simulations using molecular dynamics and continuum mechanics models can play significant roles in this development. Currently, the continuum approach seems to be the only feasible approach for such large scale analysis. In this paper, effective MECHANICAL PROPERTIES of CNT-based composites are evaluated using a square representative volume element (RVE) based on the continuum mechanics and Finite Element Method (FEM).Formulas are derived based on the elasticity theory to extract the effective material constants from solutions for the square RVEs under two load cases. Next, CNT ASPECT RATIO effects on the Nano composite MECHANICAL PROPERTIES are investigated. Results indicate that increasing CNT ASPECT RATIO results in an increase in Nano composite longitudinal modulus and a decrease in Nano composite transverse modulus. Also, increasing the CNT ASPECT RATIO resulted in a decrease in Nano composite Poisson’s ratio in the x-y plane and an increase in Nano composite Poisson’s ratio in the x-z plane.
