Abstract
A composite structural reinforcement has a keyed reinforcement member in which a thermally expandable resin strip is mechanically retained. The mechanical interlock permits the resin to be secured to the member without heat or an adhesive.
Claims20
A reinforcement member for structurally reinforcing a hollow member, said reinforcement member comprising:
- a member having a body, said body defining a channel for receiving a strip of uncured thermally expandable resin therein, said body further defining a mechanical interlocking means at said channel;
- and
- an uncured thermally expandable resin strip disposed in said channel, said uncured thermally expandable resin strip having a surface which is shaped to mate with said channel such that said mechanical interlocking means mechanically retains said uncured thermally expandable resin strip in said channel.
A reinforcement member for structurally reinforcing a hollow member, said reinforcement member comprising:
- a metallic or high-strength thermoplastic member defining a channel for receiving uncured thermally expandable epoxy-based resin therein, said metallic member further defining a mechanical interlocking means at said channel;
- and
- an uncured thermally expandable epoxy-based resin disposed in said channel, said uncured thermally expandable epoxy-based resin having a surface which is shaped to mate with said channel such that said mechanical interlocking means mechanically retains said uncured thermally expandable epoxy-based resin in said channel.

- and
- an uncured thermally expandable resin strip disposed in said channel, said uncured thermally expandable resin strip having a surface which is shaped to mate with said channel such that said mechanical interlocking means mechanically retains said uncured thermally expandable resin strip in said channel, said uncured thermally expandable resin strip being retained in said channel solely by said mechanical interlocking means.
