COMPOSITE STRUCTURAL REINFORCEMENT MEMBER

摘要

A reinforced structural member (18) has a w-shaped reinforcement member (32) that carries a thermally expandable resin based material (36). The w-shaped reinforcement member (32) is placed in the channel (34) of a hollow structural member (20) over a transverse pin (30) which fits through the slot of the reinforcement member (32). The structural member (20) is heated to expand the resin based material (36) which locks the reinforcement member (32) in place, thereby significantly strengthening the structural member.
