Carbon nanotubes (CNT) and coiled carbon nanotube(CCNT) have exceptional properties and improvemechanical properties of nanocomposites. In this paper themulti-scale model by ABAQUS is developed,Representative volume element (RVE) with randomdispersion of nano fillers generates and RVE based finiteelement analysis is proposed to predict the elastic propertiesof CCNT nanocomposites and obtain a stress - strain curvefor nanocomposites. Influence of volume fraction (VF) andhelix angle, on overall stress-strain curve response havebeen investigated. Results show when volume fraction andhelix angle increase the strength of nanocomposites isenhanced and stress- strain curve is improved.
