Enhancement of out-of-plane mechanical properties of carbon fiber reinforced epoxy resin composite by incorporating the multi-walled carbon nanotubes

Abstract In this study, epoxy hybrid nanocomposites reinforced by carbon fibers (CFs) were fabricated a filament winding. To improve out-of-plane (transverse) mechanical properties, 0.5 and 1.0 Wt.% multi-walled nanotubes (MWCNTs) embedded into epoxy/CF composites. The MWCNTs well dispersed the resin without using any additives. transverse properties of epoxy/MWCNT/CF evaluated tensile test in vertical direction to CFs (90º tensile) flexural tests. fracture surfaces composites studied scanning electron microscopy (SEM). SEM observations showed that bridging is one mechanisms enhancement results 90º proved strength elongation at break nanocomposite with improved up 53% 50% comparison laminate composite, respectively. Furthermore, strength, secant modulus, epoxy/1.0 MWCNT/CF increased 15%, 7%, 9% compared
