Abstract
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.
