TUBULAR STRUCTURAL REINFORCING MEMBER WITH THERMALLY EXPANSIBLE FOAMING MATERIAL

摘要

A reinforcing member (10) for receiving thereon a thermally expansible reinforcing material (22) includes a tubular carrier (20) and a fastener (26 ) mechanically affixing the reinforcing material to the carrier. The tubular carrier preferably has a continuous arcuate wall with the reinforcing materi al received on the exterior thereof. The reinforcing material may be provided a s a plurality of longitudinally spaced annular elements, an elongated sleeve, or a prism-shaped element. Upon heating, the reinforcing material expands and bonds the carrier to the structure member to provide additional strength and stiffness.
