Abstract
A needled mat adapted to reinforce a thermoplastic matrix material to form a composite, the mat including: (a) a plurality of discontinuous glass monofilaments present in an amount ranging from at least about 30 weight percent to about 99 weight percent of the mat on a total solids basis and having a filament coating composition thereon which is compatible with a thermoplastic matrix material; and (b) a plurality of discontinuous glass fiber strands and having a strand coating composition thereon which is compatible with the thermoplastic matrix material, wherein the glass monofilaments and glass fiber strands are essentially uniformly distributed throughout the mat.
