Abstract
Hardness is an important mechanical property which determines the applicability of polymer composites. Carbon Nanotubes (CNTs) invented by Iijima by arc-discharge technique. It possesses some unique properties like Young’s modulus, the values varies from 0.42 to 4.15 TPa, tensile strength of 1 TPa, density varies between 1.3 and 3 g/cm3 which is comparatively lower than commercial carbon fibers. This makes CNT as a potential reinforcement with metal and polymers for enhancement of properties. This work describes about preparation of PP-CNT composites with different ratios. Hardness of the composites were measured using Nanoindentation method and found that hardness of the PP-CNT system increases significantly with the increase of CNT proportion in the PP matrix.
