Abstract
Abstract Carbon nanotubes (CNTs) are increasingly used as reinforcing materials in polymer matrix composites because of their high stiffness, strength and resilience, as well as excellent mechanical, electrical and thermal properties. Embedding CNTs in polymer matrix composites can increase the stiffness and strength of composites significantly. In this paper, the effective elastic properties of multiscale composites (Carbon Fiber/CNTs/Epoxy) at 5% volume fraction of CNTs are evaluated using finite element method. 3-D finite element models using representative volume element (RVE) applying necessary boundary conditions are developed. For validation the results are compared with classical theories of equivalent material properties. From the results it is observed that there is good agreement between the results of finite element method and classical theories of equivalent materials properties.
