초록

Structural composite parts having a light-weight expanded polyolefin core are rendered resistant to breakage under bending stress by molding an integral skin polyurethane flexible foam around the core. The resulting composite parts have excellent compressive strength and energy absorption properties while being resistant to breakage, and are well suited for light-weight and cost effective energy management structures in vehicle interiors.

대표
청구항

[ What is claimed is:] [1.] An energy management structural composite resistant to breakage under bending stress, comprising in major part an expanded polyolefin molded part surrounded on at least one surface by an effective breakage minimizing layer of an in situ-produced integral skin polyurethane flexible foam, said integral skin polyurethane foam directly abutting said expanded polyolefin molded part.
