A chopped strand mat formed of bundles of dielectrically dried reinforcing fibers and bonding fibers is provided. The reinforcing fibers may be formed as bundles of wet reinforcing fibers with a bundle tex of about 10 to about 500. The reinforcing fibers may be formed of a single chop length of about 1 to about 1½ inches or a multi-chop length of fibers of about ½ to about 2 inches. The bonding materials may be any thermoplastic or thermosetting material having a melting point less than the reinforcing fiber. The chopped strand mat may be formed by dielectrically drying the wet reinforcement fibers, blending the reinforcement and bonding fibers, bonding the reinforcement and bonding fibers to form a chopped strand mat, compacting the mat, cooling the mat, and winding the mat into a continuous roll. The chopped strand mat contains a uniform or nearly uniform distribution of bonding fibers and bundles of dried reinforcement fibers. |
