In this study we report a novel method of dispersing multi-walled carbon nanotubes (MWCNTs) using an electrospinning depositional process onto a conventional, uncured preimpregnated composite material. The main focus is the determination of the process parameters in order to consistently and homogeneously disperse MWCNTs onto a secondary substrate. Due to the exceptional thermal, mechanical, and electrical properties that can be exploited in CNTs, a homogenous dispersion can lead to isotropy in material properties of interest-mechanical, thermal, electrical etc. By combining these materials with structural composite materials, the true spirit of a tailored engineering material can be exploited even further to induce specific properties that are desired for a particular application. Through the use of scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images, as well as vertical scanning interferometry, the resulting electrospun fibers are imaged and correlated with process parameters.
