Abstract

Multi-axial fabrics (including hybrid, multi-axial fabrics) and polymer-fiber laminates are disclosed. Bodies (e.g., cylindrical and/or flanged bodies) incorporating the fabrics and/or laminates are also disclosed. The bodies exhibit improved performance and/or reduced costs for connecting applications.

Claims (41)

1. A hybrid, multi-axial fabric comprising:

a plurality of reinforcing fibers includes a plurality of first fibers, a plurality of second fibers, and a plurality of third fibers;

wherein the first fibers have a first orientation within the fabric;

wherein the second fibers have a second orientation within the fabric, the second orientation differing from the first orientation by a first offset;

wherein the third fibers have a third orientation within the fabric, the third orientation differing from the first orientation by a second offset;

wherein the first fibers include a plurality of fourth fibers and a plurality of fifth fibers;

wherein an elastic modulus of the fourth fibers differs from an elastic modulus of the fifth fibers;

wherein the fourth fibers account for between 10 wt % to 40 wt % of the first fibers; and

wherein the fifth fibers account for between 60 wt % to 90 wt % of the first fibers.

2. The hybrid, multi-axial fabric of claim 1 , wherein the hybrid, multi-axial fabric is a unitary fabric including the reinforcing fibers.

3. The hybrid, multi-axial fabric of claim 1 , wherein the hybrid, multi-axial fabric is formed from a first fabric and a second fabric;

wherein the first fabric includes the first fibers; and

wherein the second fabric includes the second fibers and the third fibers.

4. The hybrid, multi-axial fabric of claim 3 , wherein the first fabric and the second fabric are stitched together.

5. The hybrid, multi-axial fabric of claim 1 , wherein the hybrid, multi-axial fabric is formed from a first fabric, a second fabric, and a third fabric;

wherein the first fabric includes the first fibers;

wherein the second fabric includes the second fibers; and

wherein the third fabric includes the third fibers.

6. The hybrid, multi-axial fabric of claim 5 , wherein the first fabric, the second fabric, and the third fabric are stitched together.

7. The hybrid, multi-axial fabric of claim 1 , wherein the first orientation is x; and

wherein the first offset is approximately x−10° and the second offset is approximately x+10°.

8. The hybrid, multi-axial fabric of claim 1 , wherein the first orientation is x; and

wherein the first offset is approximately x−15° and the second offset is approximately x+15°.

9. The hybrid, multi-axial fabric of claim 1 , wherein the first orientation is x; and

wherein the first offset is approximately x−20° and the second offset is approximately x+20°.

10. The hybrid, multi-axial fabric of claim 1 , wherein the first orientation is x; and

wherein the first offset is approximately x−25° and the second offset is approximately x+25°.

11. The hybrid, multi-axial fabric of claim 1 , wherein the first orientation is x; and

wherein the first offset is approximately x−30° and the second offset is approximately x+30°.

12. The hybrid, multi-axial fabric of claim 1 , wherein the first orientation is x; and

wherein the first offset is approximately x−45° and the second offset is approximately x+45°.

13. The hybrid, multi-axial fabric of claim 1 , wherein the first orientation is x; and

wherein the first offset is between x−10° and x−30° and the second offset is between x+10° and x+30°.

14. The hybrid, multi-axial fabric of claim 1 , wherein the first orientation is x; and

wherein the first offset is between x−5° and x−45° and the second offset is between x+5° and x+45°.

15. The hybrid, multi-axial fabric of claim 1 , wherein the first orientation is 0°.

16. The hybrid, multi-axial fabric of claim 1 , wherein the first orientation is 90°.

17. The hybrid, multi-axial fabric of claim 1 , wherein an absolute value of the first offset is different from an absolute value of the second offset.

18. The hybrid, multi-axial fabric of claim 1 , wherein the reinforcing fibers are selected from the group consisting of polymer fibers, carbon fibers, aramide fibers, and glass fibers.

19. The hybrid, multi-axial fabric of claim 1 , wherein the fourth fibers are H-type glass fibers and the fifth fibers are E-CR-type glass fibers.

20. The hybrid, multi-axial fabric of claim 1 , wherein a tensile strength of the fourth fibers differs from a tensile strength of the fifth fibers.
