Abstract: The composite tube comprises a tubular arrangement of knitted fiber having plurality of interlocking loops. The knitted pattern allows for variable electrical, mechanical and geometrical options. A matrix material is applied over the knitted fiber pattern and is allowed to cure. The matrix material may be applied by a vacuum bag molding process. The flexible knitted reinforcing layer allows use of an inflatable bladder to hold the reinforcing layer in the desired shape, thereby facilitating tube constructions of varying shapes and diameters. Continuous application of the matrix material avoids overlapping seams that are prone to delamination. Identification and labeling of the composite tube may be achieved with distinguishing knitted patterns having different types and colors of knitted fibers within the knitted reinforcing layer. A clear or translucent matrix material enables viewing of the underlying knitted patterns.

Abstract: The composite tube comprises a tubular arrangement of knitted fiber characterized by a plurality of interlocking loops. The tubular knitted pattern allows for variable electrical, mechanical and geometrical tube options. A matrix material is applied over the knitted fiber pattern and is allowed to cure. The matrix material may include a combination of resin and epoxy constituents. The matrix material may be applied by a vacuum bag molding process. The flexible knitted reinforcing layer allows use of an inflatable bladder to hold the reinforcing layer in the desired shape, thereby facilitating tube constructions of varying shapes and diameters. Continuous application of the matrix material avoids overlapping seams that are prone to delamination. Methods are provided for reinforcing the composite tube construction including one or more folded layers of knitted fiber, a reinforcing wrap made of knitted fiber, and an inflatable balloon element in combination with a layer(s) of knitted fiber.

Abstract: An electrically tuned composite tube comprises a tubular arrangement of a knitted reinforcement layer. Selected knitted patterns provide desired density or spacing between fibers of the reinforcement layer. A mesh element is also incorporated in the tube construction to precisely control resistivity and conductivity performance characteristics by selecting the mesh element from one or more conductive or non-conductive fibers or wires. The mesh element may include a tubular arrangement of fiber or wire provided in a knitted pattern or a woven pattern. A matrix material is applied over the knitted reinforcement layer and mesh element, and is allowed to cure for a single matrix layer. Alternatively, a first tube can be constructed with only the knitted reinforcement layer and matrix material, and the mesh element is added afterwards with another layer of matrix material applied over the exterior surface of the first tube.

Abstract: A joint for a double wall tube assembly includes an adapter having an inner wall and an outer wall connected by a web, and a flange extending from the outer wall. The inner wall is configured to receive an inner tube of a double wall tube assembly. The outer wall is configured to be connected to an outer tube of the double wall tube assembly.

Abstract: The composite tube comprises a tubular arrangement of knitted fiber characterized by a plurality of interlocking loops. Selected knitted patterns provide desired density or spacing between fibers. Selected fibers may include materials such as Kevlar®, carbon fiber, and combinations thereof. The tubular knitted pattern allows for variable electrical, mechanical and geometrical options. A matrix material is applied over the knitted fiber pattern and is allowed to cure. The matrix material may include a combination of resin and epoxy constituents. The matrix material may be applied by a vacuum bag molding process. Electrical and mechanical properties can also be controlled by selecting desired resin and epoxy constituents. The flexible knitted reinforcing layer allows use of an inflatable bladder to hold the reinforcing layer in the desired shape, thereby facilitating tube constructions of varying shapes and diameters.

Abstract: A coupling assembly for releasably interconnecting a fluid joint. The fluid joint includes confronting ends of a pair of fluid conveying members, each of which has a ferrule fixedly attached thereto, and a sleeve circumferentially surrounding the ferrules. The coupling assembly includes a pair of coupling members, a hinge assembly configured to hingedly connect the first ends of the coupling members to permit them to rotate relative to each other between an open position and a closed position where the coupling members surround the sleeve, a pair of bonding wires, each of which is coupled to a respective coupling member and configured to electrically bond the respective coupling member to the ferrules of respective fluid conveying members, and a releasable latching assembly configured to releasably secure the second ends of the coupling members together when they are in their closed position.
