Abstract
The present invention provides a needled mat adapted to reinforce a thermosetting matrix material to form a composite, composites formed therefrom, and methods related thereto. The needled mat includes a primary layer of a plurality of unidirectional continuous glass fiber strands coated with a composition which is compatible with the thermosetting matrix material and a secondary layer positioned thereon of a plurality of randomly oriented, generally continuous and/or chopped glass fiber strands coated with a composition which is compatible with the thermosetting matrix material. The mat has a total surface weight ranging from about 1300 to about 11,500 grams per square meter.
