Abstract
A method of manufacturing a composite connector for a fluid transfer conduit is provided which comprises applying continuous fibre reinforcement, oriented at least partially circumferentially and pre-impregnated with a thermoplastic polymer to a tubular mould portion which extends substantially parallel to a central axis C; applying at least one further mould portion to form a complete mould in which the continuous fibre reinforcement is enclosed and injecting a thermoplastic polymer into the mould to form a connector with a tubular hub portion and a flange portion which extends from the hub portion at an angle to the central axis C. The tubular hub portion comprises a tubular seal section with an inner layer and an outer wherein the inner layer comprises the continuous fibre reinforcement and the outer layer comprises the injected thermoplastic polymer.
