Composites of uniformly dispersed Multi-Walled Carbon Nanotubes(MWCNTs)(1wt%, 3wt%, 7wt% and 10wt%) and Polyurethane(PU) were prepared by solution mixing method. Small disc shaped specimens were fabricated for static mechanical characterization using nano-indentation techniques. Field Emission Scanning Electron Microscopy (FESEM) was done to validate the presence of MWCNTs in PU matrix. Static mechanical characterization was performed on PU/ MWCNTs nano-composites by using nano-indentation techniques. It was observed that the elastic modulus of PU/MWCNTs composites with 10wt% increased by 124.5% in comparison to pure PU. For minor composition of 3wt% the rise in elastic modulus was nearly about 50%. This significant rise in mechanical properties of PU based composite materials opens up several new avenues of engineering applications related to high strength & light weight boots, gloves, and helmets.
