Electromagnetic energy absorbing three dimensional flocked carbon fiber composite materials

Abstract

This disclosure relates to electromagnetic absorbing materials, and, more particularly, to a flocked carbon fiber composite material and methods for forming thereof. The flocked carbon fiber material comprises electrostatically applied carbon fibers, having a Z-plane component; electromagnetic modifiers; a substrate; a bonding agent; and an encapsulation agent. The method for forming said flocked carbon fiber composite material comprises preparing carbon fiber strands; separating carbon fiber strand clumps into carbon fiber strands; separating carbon fiber strands into carbon fibers; applying a bonding agent to a substrate; and electrostatically applying the carbon fibers to the substrate. The flocking device used to perform this method comprises an insulative section; a high voltage power source; a container attached to the insulative section; and a filtering section attached to the container.
