Automotive bumper systems are composed of three components, the exposed non-structural facing, the underlying structural member, and an energy management foam or hydraulic stroker system. The structural member is designed to absorb the energy of a collision and is referred to as the bumper beam. Currently, most automobiles are being manufactured with steel bumper beam systems, but as government regulations become more stringent, lightweight moldable Structural Reaction Injection Molding (SRIM) bumper beams are becoming more popular. This paper presents an engineering methodology that optimizes the preform of a reaction injection molded composite part for structural properties, while retaining sufficient flow characteristics to allow a consistently uniform and high quality product to be produced. This is accomplished by obtaining correlations between the reinforcement architecture and its permeability, wetout, and structural properties.
