Abstract

Carbon fiber reinforced polymers (CFRPs)have a highly anisotropic electrical resistivity, which limitstheir use in electrical applications. In this contribution, anelectric field was used to align multiwalled carbonnanotubes (MWCNTs) to create preferential conductivepathways within a nanocomposite and a multiscalecomposite in order to reduce their resistivity. Investigationon epoxy containing MWCNTs have shown that anelectric field of 40 V mm21 or higher applied for 2 h canlead to a reduction of the resistivity parallel to the field up to four orders of magnitude with only 0.01 wt-% loading. In thecase of CFRPs reinforced with 0.01 and 0.1 wt-% of MWCNTs, we observed reductions of the through the thicknessresistivity of 36 and 99% respectively, when an electric field of 60 V mm21 was applied for 2 h during the fabrication of thesamples.
