Abstract

A vehicle bumper system includes a structural reaction injected molded (SRIM) bumper beam that has a hollow body of generally C-shaped cross section and a SRIM reinforcement leaf that is attached to the front wall of the hollow body to increase the damage free impact resistance of the SRIM bumper beam. The reinforcement leaf can be separately molded and bonded to a front wall of the hollow body by a resilient adhesive or molded as an integral part of the hollow body. In the latter case, the integral reinforcement leaf can be solidly attached or it can be attached at the perimeter with its center separated from the front wall of the hollow body by an intervening layer of resilient material. An energy absorber pad of resilient foam material may be attached to a face of the front wall of the hollow body for increasing damage free impact resistance.
