Abstract

A structural reinforcement for an article including a carrier (10) that includes: (i) a mass of polymeric material (12) having an outer surface; and (ii) at least one fibrous composite Insert (14) or overlay (980) having an outer surface and including at least one elongated fiber arrangement (e.g., having a plurality of ordered fibers). The fibrous Insert (14) or overlay (980) is envisioned to adjoin the mass of the polymeric material in a predetermined location for carrying a predetermined load that Is subjected upon the predetermined location (thereby effectively providing localized reinforcement to that predetermined location). The fibrous insert (14) or overlay (980) and the mass of polymeric material (12) are of compatible materials, structures or both, for allowing the fibrous insert or overlay to be at feast partially joined to the mass of the polymeric material. Disposed upon at least a portion of the carrier (10) may be a mass of activatable material (126). The fibrous insert (14) or overlay (980) may include a polymeric matrix that includes a thermoplastic epoxy.

First claim

What is claimed is:

1. A device comprising:
i. a carrier; and
ii. a fibrous insert having at least one elongated fiber arrangement of a plurality of ordered fibers;
wherein the fibrous insert is joined to the carrier by an interface portion, and the fibrous insert extends from an upper surface to a lower surface of the carrier; and wherein the at least one elongated fiber arrangement is distributed in a thermoplastic material.

2. The device of claim 1 , wherein the at least one elongated fiber arrangement includes a material that is the same material as the thermoplastic material.

3. The device of claim 2 , wherein the at least one elongated fiber arrangement is a woven fiber arrangement.

4. The device of claim 3 , wherein the plurality of ordered fibers are glass fibers, mineral fibers, carbon fibers, polymeric fibers, or any combination thereof.

5. The device of claim 1 , wherein the thermoplastic material is an epoxy-based material.

6. The device of claim 5 , wherein the carrier includes ribs extending in a transverse direction relative to a longitudinal axis of the carrier.

7. The device of claim 6 , wherein the fibrous insert is positioned between the ribs.

8. The device of claim 7 , wherein the fibrous insert is recessed from an outer surface of the carrier.

9. The device of claim 8 , wherein an activatable material is disposed over at least a portion of the carrier.

10. The device of claim 9 , wherein the activatable material is free of contact with the fibrous insert.

11. The device of claim 5 , wherein the fibrous insert includes a plurality of layers each having an elongated fiber arrangement oriented in a different manner.

12. The device of claim 11 , wherein the device includes a polymeric material located in between and in direct planar contact with both the carrier and the fibrous insert.

13. The device of claim 12 , wherein the polymeric material is a film.

14. The device of claim 13 , wherein the carrier is a pultruded epoxy material.

15. The device of claim 14 , wherein a sealant material is disposed on at least a portion of the carrier.

16. The device of claim 1 , wherein an outer surface of the fibrous insert is positioned on top of, and is co-extensive with, an outer surface of the carrier.

17. The device of claim 16 , wherein the carrier is free of knit lines or other imperfections.

18. The device of claim 17 , wherein the fibrous insert is visible from both a top and a bottom of the carrier.

19. The device of claim 18 , wherein the fibrous insert is inserted into the carrier and only an upper surface of the fibrous insert is exposed.
