Abstract

Described herein are embodiments of a pressure hose having an improved reinforcement layer. In some embodiments, the reinforcement layer of the pressure hose has a reinforcement volumetric ratio (RVR) of greater than or equal to 110%. The reinforcement layer can include a plurality of braided beams, with each beam comprising a plurality of ends. In some embodiments, the plurality of ends within a beam are arranged in a multi-layer orientation. In some embodiments, the number of ends and the end orientation within each beam is identical amongst all beams in the reinforcement layer. The shape, size, and arrangement of the ends within a beam can all be adjusted to increase the surface area to volume ratio and, correspondingly, the RVR of the reinforcement layer.

First claim

We claim:

1. A reinforcement layer, comprising:
a plurality of beams braided together in the form a hollow, cylindrically-shaped body,
wherein each beam in the plurality of beams comprises a plurality of ends;
wherein the plurality of ends within each beam are arranged in a multiple-layer orientation such that the ends within the beam have varying overall length;
wherein each beam of the plurality of beams includes the same number of ends arranged in an identical multiple-layer orientation such that all of the beams in the reinforcement layer have the same overall length; and
wherein the reinforcement layer has a reinforcement volumetric ratio (RVR) of greater than or equal to 126%.

2. The reinforcement layer of claim 1 , wherein the number of ends in each beam is greater than or equal to 14.

3. The reinforcement layer of claim 1 , wherein the diameter of the ends in each beam is the range of from 0.2 mm to 0.5 mm.

4. The reinforcement layer of claim 1 , wherein the ends within each beam have a circular cross section, and the plurality of ends comprises a first group of ends having a first diameter and a second group of ends having a second diameter larger than the first diameter.

5. The reinforcement layer of claim 4 , wherein the first group of ends having a first diameter are located proximate the exterior of the beams and the second group of ends having a second diameter are located proximate the center of the beams.

6. The reinforcement layer of claim 1 , wherein the plurality of ends comprises a first group of ends having a first cross-sectional shape and a second group of ends having a second cross-sectional shape different from the first cross-sectional shape.

7. The reinforcement layer of claim 1 , wherein the plurality of ends comprises a first group of ends having a first tensile strength and a second group of ends having a second tensile strength greater than the first tensile strength.

8. The reinforcement layer of claim 7 , wherein the first group of ends having a first tensile strength are located proximate the exterior of the beams and the second group of ends having a second tensile strength are located proximate the center of beams.

9. The reinforcement layer of claim 1 , wherein the plurality of ends is a plurality of carbon fiber ends.

10. The reinforcement layer of claim 1 , wherein the plurality of ends comprises a first group of ends that are carbon fiber ends and a second group of ends that are steel ends.

11. A reinforcement layer, comprising:
a first inner layer, and
a second outer layer, wherein both the first layer and the second layer comprise:
a plurality of beams braided together, each of the beams comprising:
a plurality of ends grouped together in a multi-layered orientation;
wherein each of the plurality of beams comprises an identical number of ends arranged in an identical multi-layered orientation;

wherein the reinforcement layer has a reinforcement volumetric ratio (RVR) of greater than or equal to 110%; and
wherein the first inner layer and the second outer layer each have a braid angle less than 54° 44′.

12. The reinforcement layer of claim 11 , wherein the braid angle of the first inner layer is less than the braid angle of the second outer layer.

13. The reinforcement layer of claim 11 , wherein the braid angle of the first inner layer is about 94% of the braid angle of the second outer layer.

14. The reinforcement layer of claim 11 , wherein the plurality of ends within each beam are provided in a twisted configuration.

15. The reinforcement layer of claim 11 , wherein the plurality of ends are composite ends made from two or more materials.

16. The reinforcement layer of claim 15 , wherein the composite ends have a co-axial composite structure.

17. The reinforcement layer of claim 15 , wherein the composite ends have a matrix composite structure.

18. The reinforcement layer of claim 11 , wherein the ends within each beam vary by two or more of size, cross-sectional shape, material, and tensile strength.

19. The reinforcement layer of claim 11 , wherein the ends within each beam vary by three or more of size, cross-sectional shape, material, and tensile strength.

20. The reinforcement layer of claim 11 , wherein the ends within each beam vary by each of size, cross-sectional shape, material, and tensile strength.
