Abstract:
Polypropylene(PP) composites were fabrication with minor(5wt% and 10wt%) compositions ofMulti-Walled Carbon
Nanotubes(MWCNTs) using solvent mixing method. These composites were characterized to evaluate the effect of MWCNTs
on the mechanical properties of PP. Nano-indentation tests were performed on these composites to obtain the variation in
hardness and elastic modulus by varying the MWCNTs compositions in PC. It was observed that, for 5% MWCNT/PP
composition the elastic modulus and hardness were enhanced.Both elastic modulus and hardness increased by 21% and 27.1%
respectively in comparison to pure PP while for 10wt% MWCNT/PP composite this enhancement in modulus and hardness was
27.6% and 75% respectively. Presence of MWCNTs provides resistance for the propagation of shear bonds and hence
deformation of PP under external loads gets reduced.
