## Abstract

A hose assembly includes an inner hose component, a first braid of reinforcement fiber material that extends around the inner hose component, and a second braid of reinforcement fiber material that extends around the first braid. The first braid and the second braid each has a 3 over 3 braid design, and the first braid has a first modulus and the second braid has a second modulus different from the first modulus. The first braid may be a high strength braid having a strength greater than a strength of the second braid, and the second braid may be a high modulus braid having a modulus greater than a modulus of the first braid. The hose assembly optionally may have a third braid with a high angle configuration of the braid segments. The hose assembly may be combined with an enhanced fitting for securing the hose assembly to fluid system equipment.

## Claims

### Claim 1

A hose assembly comprising:
an inner hose component;
a first braid of reinforcement fiber material that extends around the inner hose component; and
a second braid of reinforcement fiber material that extends around and contacts the first braid;
wherein the first braid and the second braid each has a 3 over 3 braid design; and
the first braid has a first modulus and the second braid has a second modulus that is different from the first modulus;
wherein an aspect ratio of the first braid and the second braid comprises a ratio of a wavelength of braid segments to an amplitude of braid segments, and the aspect ratio of the second braid is greater than the aspect ratio of the first braid.

### Claim 2 (depends on 1)

The hose assembly of claim of claim 1, wherein the aspect ratio of the first braid and the second braid is at least six.

### Claim 3 (depends on 1)

The hose assembly of claim 1, wherein the aspect ratio of the second braid is at least 30% higher than the aspect ratio of the first braid.

### Claim 4 (depends on 1)

The hose assembly of claim 1, wherein the first braid is a high strength braid having a strength greater than a strength of the second braid.

### Claim 5 (depends on 4)

The hose assembly of claim 4, wherein the second braid is a high modulus braid having a modulus greater than a modulus of the first braid.

### Claim 6 (depends on 1)

The hose assembly of claim 1, wherein the first braid and the second braid are made of a para-aramid fiber material.

### Claim 7 (depends on 1)

The hose assembly of claim 1, further comprising an outer sheath that extends around the second braid.

### Claim 8 (depends on 1)

The hose assembly of claim 1, further comprising a third braid of reinforcement fiber material that extends around the second braid, wherein the third braid has a 3 over 3 braid design.

### Claim 9 (depends on 8)

The hose assembly of claim 8, wherein the third braid has a high angle configuration in which braid segments are oriented an angle of at least 55 degrees relative to a neutral line corresponding to a longitudinal axis of the hose assembly.

### Claim 10 (depends on 9)

The hose assembly of claim 9, wherein the angle of the high angle configuration is 57 to 60 degrees.

### Claim 11 (depends on 8)

The hose assembly of claim 8, wherein the third braid is made of a para-aramid fiber material.

### Claim 12 (depends on 8)

The hose assembly of claim 8, further comprising an outer sheath that extends around the third braid.
