Thermoplastic reinforced hose construction
First Claim
1. A flexible hose adapted for conveying fluids under pressure, said hose extending in an axial direction along a central longitudinal axis to an indefinite length, and in a radial direction circumferentially about said longitudinal axis, said hose comprising:
- a core tube having a circumferential inner core tube surface and an opposing circumferential outer core tube surface;
a first reinforcement layer surrounding the outer core tube surface, said first reinforcement layer being formed of one or more filaments of at least a first fiber; and
at least a second fiber reinforcement layer surrounding said first reinforcement layer, said second reinforcement layer being formed of one or more filaments of at least a second fiber, wherein said second reinforcement layer is bonded to said first reinforcement layer by a bonding agent, only a portion of the filaments of said first reinforcement layer and of said second reinforcement layer being wetted by said bonding agent.

Abstract
A flexible hose adapted construction for conveying fluids under pressure. The construction includes a core tube having a circumferential inner core tube surface and an opposing circumferential outer core tube surface. A first reinforcement layer surrounds the outer core tube surface, and is formed of one or more filaments of a first fiber. A second fiber reinforcement layer surrounds the first reinforcement layer, and is formed of one or more filaments of a second fiber. The first and second reinforcement layers are bonded together by means of a bonding agent such as an adhesive, resin, plasticizer, tackifier, or solvent, the application of which is controlled to wet only a portion of the filaments of the reinforcement layers.

33. A method of making a flexible hose adapted for conveying fluids under pressure, said hose extending in an axial direction along a central longitudinal axis to an indefinite length, and in a radial direction circumferentially about said longitudinal axis, said method comprising the steps of:
-
(a) providing a core tube having a circumferential inner core tube surface and an opposing circumferential outer core tube surface;
(b) providing a first reinforcement layer around the outer core tube surface, said first reinforcement layer being formed of one or more filaments of at least a first fiber;
(c) providing at least a second fiber reinforcement layer around said first reinforcement layer, said second reinforcement layer being formed of one or more filaments of at least a second fiber; and
(d) bonding said second reinforcement layer to said first reinforcement layer by a bonding agent which is applied in a flowable phase which wets only a portion of the filaments of said first reinforcement layer and of said second reinforcement layer. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65)
