Multilayer hose and associated method
In certain embodiments, a hose includes an inner tube, a filler material, and an outer cover. The inner tube has a cross-sectional shape and includes a cavity for transporting a substance. The filler material is provided around an outer periphery of the inner tube. The filler material includes a self-sealing material or a self-healing material. The outer cover is provided around an outer periphery of the filler material such that the filler material is between the outer cover and the inner tube. The outer cover has a D-shaped cross-sectional shape.
1. A hose, comprising:
an inner tube having a cross-sectional shape, the inner tube comprising a cavity for transporting a substance;
a filler material provided around an outer periphery of the inner tube, the filler material comprising a self-sealing material or a self-healing material;
an outer cover provided around an outer periphery of the filler material such that the filler material is between the outer cover and the inner tube, the outer cover having a D-shaped cross-sectional shape that comprises a first elongated edge, a thickness of the filler material between the inner tube and the first elongated edge of the outer cover being less than a thickness of the filler material between the inner tube and at least one other edge of the outer cover.
2. The hose of claim 1 , wherein the outer cover comprises a curved edge opposite the first elongated edge.
3. The hose of claim 2 , wherein the inner tube is positioned closer to the first elongated edge of the outer cover than to the curved edge of the outer cover such that a greater amount of filler material is positioned between the inner tube and the curved edge of the outer cover than between the inner tube and the first elongated edge of the outer cover.
4. The hose of claim 2 , wherein the outer cover further comprises a second elongated edge extending from a first end of the first elongated edge and a third elongated edge extending from a second end of the first elongated edge, the curved edge coupling the second elongated edge and the third elongated edge.
5. The hose of claim 1 , wherein the inner tube comprises a reinforcement layer and a flexible polymer.
6. The hose of claim 1 , wherein the cross-sectional shape of the inner tube is a D-shape.
7. The hose of claim 1 , wherein the cross-sectional shape of the inner tube is ovular or circular.
8. The hose of claim 1 , wherein the outer cover comprises a film barrier, an outer coating, or a braided layer.
9. A machine, comprising:
a surface configured to be oriented toward a potential threat;
a hose, the hose comprising:
an inner tube comprising a cavity for transporting a substance;
a filler material provided around an outer periphery of the inner tube, the filler material comprising a self-sealing material or a self-healing material;
an outer cover provided around an outer periphery of the filler material such that the filler material is between the outer cover and the inner tube, the outer cover having a cross-sectional shape that comprises at least one flat edge, a thickness of the filler material between the inner tube and the at least one flat edge of the outer cover being less than a thickness of the filler material between the inner tube and at least one other edge of the outer cover, the at least one flat edge positioned toward a portion of the surface such that a greater amount of filler material is configured to be oriented toward the potential threat.
10. The machine of claim 9 , wherein the cross-sectional shape of the outer cover and a cross-sectional shape of the inner tube are substantially a same cross-sectional shape.
11. The machine of claim 9 , wherein the cross-sectional shape of the outer cover is a D-shape.
12. The machine of claim 9 , wherein the outer cover comprises a curved edge opposite the at least one flat edge.
13. The machine of claim 12 , wherein the inner tube is positioned closer to the at least one flat edge of the outer cover than to the curved edge of the outer cover such that a greater amount of filler material is positioned between the inner tube and the curved edge of the outer cover than between the inner tube and the at least one flat edge of the outer cover.
14. The machine of claim 12 , wherein:
the at least one flat edge comprises:
a first flat edge positioned toward the portion of the surface the outer cover;
a second flat edge extending from a first end of the first flat edge; and
a third flat edge extending from a second end of the first flat edge; and
the curved edge couples the second flat edge and the third flat edge.
15. The machine of claim 9 , wherein the inner tube comprises a reinforcement layer and a flexible polymer.
16. The machine of claim 9 , wherein a cross-sectional shape of the inner tube is ovular or circular.
17. The machine of claim 9 , wherein the outer cover comprises a film barrier, an outer coating, or a braided layer.
18. A hose, comprising:
an inner tube comprising a cavity for transporting a substance;
a filler material provided around an outer periphery of the inner tube, the filler material comprising a self-sealing material or a self-healing material;
an outer cover provided around an outer periphery of the filler material such that the filler material is between the outer cover and the inner tube, the outer cover having a cross-sectional shape that comprises at least one flat edge, a thickness of the filler material between the inner tube and the at least one flat edge of the outer cover being less than a thickness of the filler material between the inner tube and at least one other edge of the outer cover.
19. The hose of claim 18 , wherein the cross-sectional shape of the outer cover and a cross-sectional shape of the inner tube are substantially a same cross-sectional shape.
20. The hose of claim 18 , wherein a cross-sectional shape of the inner tube is ovular or circular.
