Abstract
A composite fiber reinforced plastic member and its method of manufacture to provide a high-strength light-weight part particularly suitable for use as a structural component. The composite member comprises a body or web comprised of a glass fiber reinforced thermosetting resin matrix having a carbonized fiber reinforced compatible resin stratum integrally bonded by the resin matrix over selected areas thereof corresponding to areas of anticipated high stress. The component is produced by molding under pressure and heat a moldable assembly comprising a first sheet of a flowable heat curable resin containing glass fibers having one or a plurality of second sheets comprised of a compatible flowable heat curable resin containing carbonized fibers disposed over selected areas of the first sheet. During the compression molding operation, the resins in the first and second sheets flow to conform with and fill the mold cavity and the resins cure forming a smooth surfaced composite integral assembly of high strength.
