Abstract: A composite structure comprising a core portion having a pair of generally opposed surfaces. A first fibrous layer is disposed on a first surface of the core portion and has a plurality of fibres disposed substantially parallel to the first surface. A second fibrous layer disposed on a second surface of the core portion and has a plurality of fibres disposed substantially parallel to the second surface. A first polymer layer is disposed over the first fibrous layer and a second polymer layer is disposed over the second fibrous layer. The first fibrous layer is partially embedded in both the core portion and the first polymer layer. The second fibrous layer is partially embedded in the core portion and the second polymer layer. The present composite structure may be used in structural and/or non-resilient components of the vehicle. Such components include exterior body panels (e.g., TONNEAU covers), door panels, beds for pickup trucks and the like.

Abstract: The invention pertains to a water blown integral skin polyurethane foam having a skin with good abrasion resistance. The foam is manufactured by employing as a polyol composition a polyol having a functionality of from 1.75 to 2.65 and a molecular weight of from 1500 to 5000 along with a surfactant and water as a blowing agent. The particular surfactant is a particular siloxane or an ethylene oxide adduct of octylphenol.
