para-Aramid fabric-reinforced polymer composites have excellent impact resistance and elasticity because para-aramid exhibits high strength, stiffness-to-weight ratio, and impact toughness. Multi-walled carbon nanotubes (MWCNT) are a promising material for improving the mechanical, thermal, and electrical properties of polymer composites. In this study, the effect of MWCNT anchored to para-aramid fabric on the properties of para-aramid fabric-reinforced vinyl ester (p-AF/VE) composites was explored. To anchor the MWCNT to the p-AF, highly diluted phenolic resin was used as an anchoring agent. Prior to preparation of the MWCNT-anchored p-AF, the MWCNT were dispersed in methanol. p-AF/VE composites with the MWCNT are fabricated by compression molding. The effect of MWCNT-anchored p-AF on their thermal and mechanical properties and energy absorption behavior through high-velocity impact tests. Pristine p-AF/VE composite without MWCNT was also prepared for comparison of the properties. |
