Impact resistance of epoxy-based materials filled with carbon nanotubes

The resistance of polymer composite materials based on epoxy resin with multi-walled carbon nanotubes (MWCNTs) as modifying additives under high-velocity impact effects was studied. Samples consisting of layers with different concentrations of MWCNTs in the polymer matrix were synthesized and studied. It was shown that carbon nanotubes improve the resistance of composites to impact effects. The highest values of the impactor kinetic energy absorption capacity are achieved by composites at a concentration of 7 wt.% CNTs ($\sim$3 times higher than without MWCNT filler).
