Evaluation of Mechanical Properties of Carbon Fiber-Reinforced Multiwall Carbon Nanotube-Based Nanocomposites

In the present study, reinforcement of treated multiwall carbon nanotubes (MWCNTs) in the carbon fiber matrix was done. MWCNTs are mixed into epoxy resin in different weight ratio (0.0, 0.2, and 0.5 wt% of weight of resin). By varying the percentage of MWCNTs into the epoxy resin, different sheets are prepared by applying the resin to carbon fiber sheets. Mechanical properties are tested as per the ASTM Standards. From the results, it was found that composite with 0.5 wt% of treated MWCNTs produced better mechanical strength among all the other samples because of the uniform dispersion of treated MWCNTs in the epoxy as compared to non-treated MWCNTs.
