**2.12 Elastic properties of coiled CNT reinforced Nano composite**

With the invention of Carbon nanotube with advanced material properties, various nano composites had been developed [14]. A new algorithmic representative volume element (RVE) and finite element method had been formulated to find the elastic properties of coiled Carbon NanoTubes (CCNT). The elastic properties had been explored with the respect to interphase, fiber volume fraction, orientation, number of coils, tube diameter, coil diameter and helix angle using FEM. The elastic moduli of the nanocomposites were found to decrease with increase in the number of coils. Also it had been found that SWNT offers better reinforcement when compared with CCNT reinforcement.
