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 least 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 or overlay joined to the carrier, the fibrous insert or overlay having at least one elongated fiber arrangement of a plurality of ordered fibers distributed in a polymeric material,
wherein the polymeric material includes a reaction product of a diepoxide and a mono primary amine or a di-secondary amine, and the plurality or ordered fibers is mixed with the reaction product prior to injection molding, extruding, or pultruding the resulting mixture to form the fibrous insert or overlay.

2. The device of claim 1 , wherein the carrier includes a thermoplastic material.

3. The device of claim 2 , wherein the fibrous insert or overlay includes at least one layer in the form of a tape material that is made generally of the same material as the carrier.

4. The device of claim 2 , wherein the at least one elongated fiber arrangement includes a material that is made generally of the same material as the carrier.

5. The device of claim 4 , wherein the fibrous insert or overlay and the carrier are chemically fused together.

6. The device of claim 5 , wherein the at least one elongated fiber arrangement is a woven fiber arrangement.

7. The device of claim 1 , wherein the outer surface of the fibrous insert or overlay is generally co-extensive with the outer surface of the carrier.

8. The device of claim 7 , wherein the fibrous insert or overlay is disposed on top of an outer surface of the carrier.

9. The device of claim 1 , wherein the plurality of ordered fibers includes fibers selected from mineral fibers, polymeric fibers, carbon fibers, metal fibers, natural fibers, or a combination thereof.

10. The device of claim 9 , wherein the plurality of ordered fibers each have a length of at least 1 mm.

11. The device of claim 1 , wherein the plurality of ordered fibers are distributed in the polymeric material in the form of a random distribution, a weave, a non-woven mat, a plurality of generally axially aligned, a plurality or axially intertwined fibers, or a combination thereof.

12. The device of claim 1 , further comprising: an activatable material disposed over at least a portion of both the carrier and the fibrous insert or overlay.

13. The device of claim 1 , wherein an outer surface of the carrier is free of knit lines or other imperfections visible to the naked eye.

14. The device of claim 1 , wherein the device has a generally continuous profile along its length.

15. The device of claim 1 , wherein the fibrous insert or overlay is joined to the carrier by an interface portion, and the fibrous insert or overlay extends from an upper surface to a lower surface of the carrier, and the fibrous insert is visible from both a top and a bottom of carrier.

16. The device of claim 1 , wherein the fibrous insert or overlay is inserted into the carrier and only an upper surface of the fibrous insert or overlay is exposed.

17. The device of claim 1 , wherein the carrier includes a plurality of ribs extending in a transverse direction relative to a longitudinal axis of the carrier.

18. The device of claim 17 , wherein the fibrous insert or overlay is positioned between the plurality of ribs and the fibrous insert or overlay is recessed from an outer surface of the carrier.

19. The device of claim 18 , wherein an activatable material is disposed over at least a portion of the carrier free of contact with the fibrous insert or overlay.

20. The device of claim 1 , wherein the fibrous insert or overlay includes a plurality of layers each having an elongated fiber arrangement oriented in a different manner.
