Abstract

A method of manufacturing a composite (e.g. fiber-reinforced polymer) connector for a fluid transfer conduit comprises: manufacturing a tubular pre-form which extends substantially parallel to a central axis C, the tubular pre-form comprising continuous circumferentially-oriented fiber reinforcement; manufacturing a continuous fiber pre-form net, the pre-form net comprising a support layer and continuous fiber reinforcement, the continuous fiber reinforcement being secured by being stitched to the support layer; placing the tubular pre-form and the pre-form net together into a mould to form a tubular hub portion from the tubular pre-form and a flange portion from the pre-form net, the flange portion extending from the hub portion at an angle to the central axis C; and introducing polymer into the mould so as to form a composite connector comprising the flange portion and the hub portion.
