Abstract: The non-conductive polymer matrix impedes carbon fiber’s excellent electrical conductivity in the carbon fiber reinforced polymer (CFRP) composites. Due to its low z-directional DC electrical conductivity, CFRP composites has limited application capabilities in lightning strike protection (LSP) and electromagnetic shielding. This research demonstrates the ability to manufacture lightweight and electrically conductive (i.e., z-direction) CNFs z-threaded porous CFRP composite utilizing just 50 % of epoxy used in the traditional composites. In this study, the radial flow alignment technique was used to z-thread carbon nanofibers (CNFs) into the carbon fiber fabric. Experimental results showed the z-directional DC electrical conductivity in the 0.85 wt% CNF z-threaded porous (P-ZT-CFRP) was 21.06 S/m, which is an increase of 778 % and 107 % compared to the traditional composite sample and P-CFRP (without nano-reinforcement) laminate, respectively.
