A hollow reinforced structural member (50) has a bulkhead (68) having a layer of thermally expanded resin (74) disposed between opposed side walls (70,72). A sleeve (81) is retained within the resin layer (74) and is oriented perpendicular to the longitudinal axis of the reinforce structural member (50). The sleeve (74) is in alignment with bolt holes (66) in opposite sides of the reinforced structure (50) such that a bolt (84) can be inserted there through. A component can then be bolted to the reinforced structural member at the site of the reinforcement. The invention not only increases the strength of the part, but also reduces vibration and noise transmission. The reinforced structure (50) may be an automotive (front) rail section. <IMAGE> |
