Exposed structural corner reinforcement
The present teachings generally relate to a structural reinforcement, a body member comprising the structural reinforcement, and a method of using the structural reinforcement. The structural reinforcement comprises a first wall, a second wall extending from a first side of the first wall. Spacer legs extend from a second side of the first wall and define a first channel Spacer legs extend from a second side of the second wall and define a second channel. The structural reinforcement is configured to reinforce a joint.

(a) a first wall,
(b) a second wall extending perpendicularly from an edge of a first side of the first wall,
(c) a third wall coupled to and extending perpendicularly between the first wall and the second wall,
(d) one or more spacer legs extending from a second side of the first wall and defining a first channel,
(e) one or more spacer legs extending from a second side of the second wall and defining a second channel, and
(f) a curable adhesive disposed in the first channel and the second channel and on the third wall;
wherein the structural reinforcement is configured to reinforce a joint; and
wherein the one or more spacer legs of the first wall and the one or more spacer legs of the second wall each include two spacer legs coupled to opposing edges respectively of the first wall and the second wall.
2. A body member of a vehicle having the joint, the body member comprising the structural reinforcement according to claim 1 .
3. The body member according to claim 2 , wherein the structural reinforcement is adapted to located on two or three interfacing surfaces of the joint.
4. The structural reinforcement according to claim 1 , wherein the structural reinforcement comprises an opening on the first wall, the second wall, the third wall, or any combination thereof; and wherein the opening accepts a fastener to fasten to the structural reinforcement to the joint.
5. The structural reinforcement according to claim 4 , wherein the structural reinforcement comprises one or more base materials, one or more reinforcement components, or both.
6. The structural reinforcement according to claim 5 , wherein the one or more base materials are selected from a polyamide, a polyester, a polypropylene, a polyethylene, a polysulfone, a thermoplastic imide, a polyether imide, a polyether sulfone, or any combination thereof.
7. The structural reinforcement according to claim 6 , wherein the one or more reinforcement components are selected from mineral reinforcements, glass beads, glass bubbles, glass fibers, aramid fibers, carbon fibers, ceramic fibers, nylon fibers, the like, or any combination thereof.
8. The structural reinforcement according to claim 6 , wherein the curable adhesive comprises polyvinyl butyral, a thermoplastic epoxy, an epoxy-elastomer adduct, or any combination thereof.
9. The structural reinforcement according to claim 8 , wherein the curable adhesive is a heat-activated epoxy.
10. The structural reinforcement according to claim 9 , wherein the curable adhesive is disposed as one or more strips within each of the first and second channels.
11. The structural reinforcement according to claim 9 , further comprising a fourth wall coupled to and extending perpendicularly between the first wall and the second wall, the fourth wall being in opposing relationship to the third wall.
12. The structural reinforcement according to claim 11 , wherein the third wall and the fourth wall extend from corner-to-corner of the first and second walls.
13. The structural reinforcement according to claim 12 , wherein the curable adhesive is disposed as two strips within each of the first and second channels.
14. A structural reinforcement, for a vehicle, comprising: a first wall, a second wall extending perpendicularly from an edge of a first side of the first wall, a third wall coupled to and extending perpendicularly between the first wall and the second wall, two spacer legs extending from a second side of and from opposing edges of the first wall and defining a first channel, two spacer legs extending from a second side of and from opposing edges of the second wall and defining a second channel, and a curable adhesive disposed as two discrete strips in each of the first and second channels, and on the third wall; wherein the structural reinforcement is configured to reinforce a joint; wherein the first wall, the second wall, or both comprise an opening adapted to accept a fastener; and wherein the structural reinforcement is fabricated from a fiber-filled polymeric material.
15. The structural reinforcement according to claim 14 , wherein the curable adhesive comprises polyvinyl butyral, thermoplastic epoxy, epoxy-elastomer adduct, or any combination thereof.
16. The structural reinforcement according to claim 15 , wherein the curable adhesive is a heat-activated epoxy.
17. A reinforced vehicle joint system comprising: (a) a joint having three interfacing surfaces; (b) a structural reinforcement comprising: a first wall, a second wall extending perpendicularly from an edge of a first side of the first wall, a third wall coupled to and extending perpendicularly between the first wall and the second wall, two spacer legs extending from a second side of and from opposing edges of the first wall and defining a first channel, two spacer legs extending from a second side of and from opposing edges of the second wall and defining a second channel, and a curable adhesive disposed as two discrete strips in each of the first and second channels, and the curable adhesive is disposed on the third wall; wherein the structural reinforcement is configured to reinforce the joint; wherein the first wall, the second wall, or both comprise an opening adapted to accept a fastener which extends into the joint; wherein the structural reinforcement is fabricated from a fiber-filled polymeric material; and wherein the two spacer legs of the first wall are engaged on a first of the three interfacing surfaces, the two spacer legs of the second wall are engaged on a second of the three interfacing surfaces, and the third wall is adhered to a third of the three interfacing surfaces via the curable adhesive.
18. The reinforced vehicle joint system according to claim 17 , wherein the curable adhesive comprises polyvinyl butyral, thermoplastic epoxy, epoxy-elastomer adduct, or any combination thereof.
19. The reinforced vehicle joint system according to claim 18 , wherein the curable adhesive is a heat-activated epoxy.
20. The reinforced vehicle joint system according to claim 19 , wherein the curable adhesive is activatable to foam.
