This article is based on a nanocomposite that is a mixture of two distinct constituents, carbon nanotube and epoxy, with remarkably different properties. There have been numeroustheories and well-known models on the mechanics of nanocomposite to predict the elastic modulus such as (Halpin-Tsai equation, shear lag, etc.)[1,2]. We proposes a new and simple model to evaluate the elastic modulus for a nanocomposite with polymer matrix. The results are found tobe reasonably satisfactory. The effect of reinforcement addition on the mechanical properties were investigated
