Polymeric engine hood assembly, vehicle front end module, vehicles comprising the same and methods of making the same

Abstract

A method of making a polymeric engine hood assembly for use in a vehicle can include applying heat to a first polymeric sheet, applying heat to a second polymeric sheet, stacking the first polymeric sheet and the second polymeric sheet, placing the stacked sheets between a first mold half and a second mold half, closing the first mold half and second mold half, applying vacuum to the space between the first polymeric sheet and the first mold half and between the second polymeric sheet and the second mold half, wherein the first polymeric sheet forms an exterior panel and wherein the second polymeric sheet forms a reinforcing structure; and attaching an exterior panel to a fender skin at a junction surface, wherein the reinforcing structure includes a connecting ridge extending transversely across the reinforcing structure, wherein the connecting ridge is configured to accept the junction surface of the exterior panel and the feeder skin.
