1. A process of forming a fiber mat comprising:
exposing a chopped fiber filler having an initial tow volume to plasma in a tube, said plasma formed in a vortex having both rotary and vertical flow components while said chopped fiber filler is being debundled to increase activation sites on said chopped fiber filler and to expand the chopped fiber filler to a lofted tow volume that is more than 50% greater than the initial tow volume, said vortex using gravity to drop and disperse said chopped fiber filler on to a moving belt;
rotating said tube to further enhance the debundling and mixing of said chopped fiber filler in the vortex;
coating said chopped fiber filler with a silane; and
crosslinking said silane coated chopped fiber filler to a thermoset resin via the activation sites.
