A composite transmission shaft includes a shaft portion, and a flanged end fitting. The flanged end fitting comprises a flared sleeve comprising a tubular portion and a flared portion, and a reinforcement portion fixed to the flared portion of the sleeve. The flanged end fitting and shaft portion have been resin transfer moulded together to form the transmission shaft.

A method for molding a composite pressure vessel liner to secure a boss to the liner is described. The method comprises providing a moldable liner having an end section with a neck and a port. A boss is positioned around the neck of the liner and the liner is heated and pressure is applied to mold the liner to form to the shape of the boss. The angle of the molded liner secures the boss in place around the liner and it is able to withstand high pressures. A tool for molding the liner and a method for using the tool is also described. The tool comprises a tool body and a pipe having external threads. The tool body abuts the liner and the boss. Winding the pipe exerts pressure on the liner, which when heated, forces the liner to mold to the shape of the boss.

An expansion tool includes a housing and an expansion head coupled to the housing. The expansion head includes a casing and a plurality of jaws extending from the casing. The plurality of jaws is movable between a closed position and an expanded position relative to a longitudinal axis. Each jaw of the plurality of jaws includes a first sizing portion extending parallel to the longitudinal axis and a second sizing portion extending parallel to the longitudinal axis. The first sizing portions of the plurality of jaws collectively define a first diameter when the plurality of jaws is in the closed position, the second sizing portions of the plurality of jaws collectively define a second diameter when the plurality of jaws is in the closed position, and the second diameter is greater than the first diameter.

A fluid conduit for aircraft, the conduit having a pipe made from thermoplastic material having a connection end which extends along a pipe axis and a connector which is intended to be mounted in the connection end by a translational movement along the pipe axis in a downstream direction, the connector having a joining portion which extends longitudinally along the connector axis and which is configured to extend into the connection end, the joining portion having a free longitudinal end which is chamfered, the free longitudinal end being configured to be radially deformed after the connector is mounted in the connection end, which has been thermally expanded beforehand, so that the conduit has an internal surface which has an internal radius which is substantially constant at the interface between the connector and the pipe.

A composite tube comprising a region of greater diameter forming a bellow. The bellow has a first side and a second side spaced apart in the axial direction of the tube. Each side of the bellow comprises at least one hole and the at least one hole on the first side is offset in relation to the at least one hole on the second side. The holes in the bellow provide increased flexibility, thereby allowing a greater amount of bending or articulation in the shaft. The holes reduce the amount of material in the sides of the bellow, thereby reducing the material stiffness and thereby increasing the flexibility.

In an aspect, a biaxially oriented pipe has a thickened end portion. The end portion has the same inner diameter as the biaxially oriented pipe and has a larger thickness than the biaxially oriented pipe. The end portion is made of the same thermoplastic polymer composition as the biaxially oriented pipe.

A composite transmission shaft includes a shaft portion, and a flanged end fitting. The flanged end fitting comprises a flared sleeve comprising a tubular portion and a flared portion, and a reinforcement portion fixed to the flared portion of the sleeve. The flanged end fitting and shaft portion have been resin transfer moulded together to form the transmission shaft.
