In the present work, epoxy resin is modified with epoxy terminated butadiene acrylonitrile (ETBN) liquid rubber and was used to make carbon fiber reinforced epoxy (C-epoxy) composites with an aim to enhance the impact, compression and damping properties. ETBN added C-epoxy composites were further modified using amino functionalized multi-walled carbon nanotubes (A-MWCNTs) at different weight ratios namely 0.5 wt%, 1.0 wt%, and 1.5 wt% and evaluated impact, compression and damping properties. Results indicate that modification of C-epoxy with ETBN enhances the properties considerably. A-MWCNTs addition to ETBN modified C-epoxy (A-MWCNTs-C-Epoxy-ETBN) further enhances the impact strength (26%), compressive strength (17%) at 1.0 wt% and damping ratio (87%) at 0.5 wt% of A-MWCNTs. The toughening mechanisms contributing to the enhancement of mechanical and damping properties of A-MWCNTs are discussed.
