Abstract

The present bumper impact beam includes pultruding polymer (e.g. thermoset polymer, preferably polyurethane) into continuous reinforcement (preferably carbon fibers or glass fibers), the reinforcement including fabrics selectively positioned and extending around corners for improved impact strength. The beam preferably has a 50%-70% fiber volume fraction that is relatively uniform throughout the part. A curved cooling support and/or beam design may be used to cause the cooled beam to have a sweep.
