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.

Chopped fiber composite systems and methods are disclosed. Sorting systems include a conveyor, an imager, a plurality of receptacles, a pneumatic device, and controller. Molding systems include a conveyor, an imager, a mold, a pneumatic device, and a controller. The controller directs the pneumatic device to alter the freefall of chopped fiber composite pieces based on characteristics of the chopped fiber composite pieces as they drop from the conveyor and into a receptacle or a mold. Sorting and molding methods include dropping chopped fiber composite pieces, detecting characteristics of the dropping pieces, and directing the pieces based on the detected characteristics.
