Polycarbonate (PC) based composites were fabricated with different concentrations of Multi Walled Carbon Nanotubes (MWCNTs) and were subjected to dynamic impact loading using Split Hopkinson Pressure Bar (SHPB). Impact tests using this instrument were performed under varying strain rates ranging from 1096 to 4017/s on pure PC samples and samples with 0.1, 0.5 and 1% by weight of MWCNT concentrations in PC. A comparison of maximum strains produced in these samples due to different strain rates was done. It was found that the maximum strain produced for every sample increases with increase in strain rate. Maximum strain is a measure of the toughness and deformation of the sample which increases as strain rate increases.
