Abstract
A woven, stabilized fabric suitable for reinforcing resin matrices is provided. The fabric comprises a woven fabric of graphite, fiberglass, aramid, etc., in which a limited amount of a resin coated fiber is woven into one direction of the fabric. Prior to weaving, the resin coated fiber is initially coated with a resin such as an epoxy, polyimide, etc., followed by drying and then weaving into the fabric with as few picks as possible. When the fabric is heated, the resin coat melts and adheres to the fabric, and imparting stabilizing properties thereto. The stabilized fabric is then set up in a mold for resin impregnation, without undergoing undesirable movement.
