Composite connectors and methods of manufacturing the same

A connection system comprising:

• a composite connector comprising:
• a hub portion comprising a tube with an inner wall which extends parallel to a central axis in an overmoulding section of the tube;
• and
• a flange portion which extends from the overmoulding section of the tube at an angle to the central axis;
• wherein the hub portion comprises a thermoplastic polymer matrix reinforced with fibre reinforcement, said fibre reinforcement including continuous circumferentially-oriented fibre reinforcement containing at least some individual constituent filaments which extend entirely around a circumference of the hub portion;
• wherein the flange portion comprises a polymer that is moulded onto the overmoulding section of the tube, and wherein no fibre reinforcement in the hub portion extends from the tube into the flange portion;
• and
• a fibre-reinforced polymer fluid transfer conduit connected to the hub portion, wherein the composition and orientation of the fibre reinforcement within the hub portion is selected such that the coefficient of thermal expansion and/or the stiffness of the hub portion matches that of the fluid transfer conduit;
• wherein the fibre-reinforced polymer fluid transfer conduit comprises continuous circumferentially-oriented fibre with a fibre angle that differs from a fibre angle of the continuous circumferentially-oriented fibre reinforcement in the hub portion by no more than 15°.
