Abstract
A method of manufacturing a composite (e.g. fibre-reinforced polymer) connector for a fluid transfer conduit includes: manufacturing a continuous fibre pre-form net 150 that is shaped to comprise a hub-forming portion 156 and a flange-forming portion 158, the continuous fibre pre-form net comprising continuous fibre reinforcement 110 and a common support layer 151 to which the continuous fibre reinforcement 110 is secured by being stitched thereto; placing the continuous fibre pre-form net 150 into a mould, the mould being shaped such that the hub-forming portion 156 forms a tubular hub portion which extends along a central axis and the flange-forming portion 158 forms a flange portion which extends from the hub portion at an angle to the central axis; and introducing polymer into the mould so as to form a composite connector comprising the flange portion and the hub portion.
