Reinforced plastic hose
View Patent ↗A hose for use in a fluid transfer system includes a first layer that is made of a plastic material and a second layer having fiber strands that are wound about the first layer. Optionally, the hose may also have additional layers to provide added strength, permeation resistance, or other properties.
1. A hose for use in a fluid transfer system, the hose comprising:
a first layer including a plastic material with an electrically conductive material dispersed therein; and
a second layer bonded to the first layer and comprising fiber strands located radially outward of the first layer, the second layer being free of a matrix material between the fiber strands, wherein the fiber strands include polyester, polyaramid, aromatic polyamide, glass, Kevlar®, graphite or combinations thereof.
2. The hose as recited in claim 1 , wherein the plastic material includes a polyamide, polyester, polyolefin, fluoropolymer, polyphenylene sulfide, polyphthalamide, a thermoplastic elastomer, or combinations thereof.
3. The hose as recited in claim 1 , wherein the first layer comprises an electrical resistivity between approximately 10 2 and 10 7 ohm/sq.
4. The hose as recited in claim 1 , wherein each of the fiber strands individually includes a coating thereon.
5. The hose as recited in claim 1 , further comprising a third layer bonded to the second layer and that includes a polymer material, the third layer located radially outwards of the first layer.
6. The hose as recited in claim 5 , wherein the third layer includes a first sublayer and a second sublayer, and the first sublayer includes a first material and the second sublayer includes a second material that is different from the first material.
7. The hose as recited in claim 5 , wherein the polymer material includes a thermoplastic, a thermoplastic elastomer, a thermoset elastomer, an elastomer, or combinations thereof.
8. The hose as recited in claim 5 , wherein the polymer material includes a polyamide, a thermoplastic elastomer, a thermoplastic urethane, chloroprene rubber, nitrile rubber, styrene-butadiene rubber, ethylene-propylene rubber, butyl rubber, ethylene acrylic rubber, Amfac®, chlorinated polyethylene rubber, or combinations thereof.
9. The hose as recited in claim 5 , further comprising a fourth layer located radially inwards of the first layer.
10. The hose as recited in claim 9 , wherein the fourth layer includes an electrically conductive material dispersed therein.
11. The hose as recited in claim 9 , wherein the fourth layer includes a fluoropolymer, polyamide, polyolefin, polyester, polyphenylene sulfide, polyphthalamide, a thermoplastic elastomer, or combinations thereof.
12. The hose as recited in claim 9 , further comprising a fifth layer located radially inwards of the fourth layer.
13. The hose as recited in claim 12 , wherein the fifth layer includes an electrically conductive material dispersed therein.
14. The hose as recited in claim 12 , wherein the fifth layer includes a fluoropolymer, polyamide, polyolefin, polyester, polyphenylene sulfide, polyphthalamide, a thermoplastic elastomer, or combinations thereof.
15. The hose as recited in claim 1 , wherein the fiber strands are spiral wound about the first layer.
16. The hose as recited in claim 1 , wherein the fiber strands are knitted or braided about the first layer.
17. The hose as recited in claim 16 , wherein the fiber strands form an angle relative to a longitudinal axis of the hose, and the angle is between about 40° and 60°.
18. The hose as recited in claim 17 , wherein the angle is about 55°.
19. The hose as recited in claim 1 , wherein the hose is secured to a tube with a connector.
20. The hose as recited in claim 19 , wherein the connector includes a crimped ferrule.
21. The hose as recited in claim 19 , wherein the connector includes a plastic overmold that at least partially surrounds respective ends of the hose and the tube.
22. The hose as recited in claim 21 , wherein the tube includes a rib extending therefrom that mechanically interlocks with the plastic overmold.
23. The hose as recited in claim 19 , wherein the metal tube is fluidly connected with at least one of a vehicle engine, a vehicle fuel vapor management system, a vehicle transmission, or a vehicle transmission fluid cooler.
24. The hose as recited in claim 1 , wherein the fibers strands are arranged as a fabric.
25. The hose as recited in claim 1 , wherein the second layer is adhesively bonded to the first layer.
26. The hose as recited in claim 1 , wherein the fiber strands are coated with an adhesive coating to bond the second layer and the first layer together.
27. The hose as recited in claim 26 , wherein the adhesive material is made of a plastic having the same composition as the plastic material of the first layer.
28. The hose as recited in claim 1 , wherein each individual fiber strand includes an adhesive coating around the respective fiber strand that bonds the second layer and the first layer together.
29. The hose as recited in claim 1 , wherein the fiber strands are moveable relative to each other in response to insertion of a tube into the hose.
30. The hose as recited in claim 1 , wherein the second layer is mechanically bonded to the first layer.
