Carbon fiber reinforced polymer (CFRP) composites are increasingly being used in a variety of industries such as aerospace and infrastructure. This investigation experimentally examines the effect of incorporating alumina nanoparticles (ANPs), non-functionalized multi-walled carbon nanotubes (NF-MWCNTs), and functionalized multi-walled carbon nanotubes (F-MWCNTs) on the off-axis stiffness and stress-relaxation of carbon fiber reinforced polymer (CFRP) composites. Epoxy- nanocomposites incorporating 0.0, 1.0, 2.0, and 3.0 wt.% ANPs; 0.0 0.5, 1.0, and 1.5 wt. % NF-MWCNTs; 0.0 0.5, 1.0, and 1.5 wt. % F-MWCNTs of the total weight of epoxy are examined. Off-axis tension stiffness and stress-relaxation tests were performed on CFRP coupons …
