From last two decades usage of composite materials in Aerospace structural applications have widely aroused many researchers to study the mechanical behaviors of Carbon Nanotubes (CNTs) reinforced Nanocomposites. Many studies have been reported superior properties of CNTs by means of various experiments, Quantum calculations and Atomic simulations. Since because all studies had conducted at Nanoscale, we could able see the wide scatter in the results. Conducting the experiments on Nanocomposites at Nanoscale is very inconceivable to predict the mechanical properties. Molecular Dynamics was vastly used by many researchers to analyze properties of CNTs in atomistic scale with various interaction potentials (Force fields). The Carbon nanotubes were assumed to be rolled from hexagonal carbon network of Sp(2) carbon atoms. The topology of carbon nanotube was derived from major parameters like Chiral indices and Chiral Vector. So many researchers has carried out wide study on the Zigzag and Armchair nanotubes. From the literature we could able see the variation between experiment and theoretical results. As of main topology parameters concerns, there is the possibility of variety of CNTs topology at one diameter like Zigzag, Armchair and Chiral. This paper mainly deals about effect of topology parameters of carbon nanotubes used in Molecular Dynamics study for analyzing the mechanical properties of CNTs based on AIREBO potential.
