Abstract: A fiber reinforced composite laminate with fibers generally oriented along two major axes and having a polyurethane resin matrix suitable for reinforcing wood based substrates such as trailer/container flooring, glulams, plywood, particle boards, laminated veneer lumber, and oriented strand board, is provided. The laminate is produced by pulling the fibers through a resin injection box, where a polyurethane resin is injected into the box to wet the fibers. The polyurethane resin wetted fiber layer is then covered with a release media on the top and bottom sides of the layer. The sandwich of fiber, resin and release media is fed to a double belt press capable of applying pressure and heat to consolidate and cure the laminate. The laminate thus made can be thinner than 0.080 inch and provides excellent flatness compared to pultruded thin laminates.
