Abstract:
A layered composite structure for a panel structure of a motor vehicle comprising:an outer layer having an inner surface and an outer surface, the outer surface defining an exposed exterior surface of the panel structure, the outer layer comprising a substantially non-cellular thermoplastic polyurethane and a cross-linker; an inner layer disposed adjacent to the inner surface of the outer layer, the inner layer comprising one or more substantially non-cellular base polymers; and a seam defining structure disposed in the inner layer or between the inner layer and the outer layer, the seam defining structure defining tear seam for fracturing in response to operation of a secondary restraint system, the seam defining structure not being visible from the exposed exterior surface, wherein the layered composite structure comprises interfacial chemical bonding between the inner surface of the outer layer and an adjacent surface of the inner layer.
