摘要： A method of manufacture of a composite component is provided, the method comprising the steps of providing two layers of pre-preg composite material, one of which has an edge adjacent a surface of the other. Pressure and, optionally, vibrational energy is applied to the edge to thereby smooth the ply drop.

摘要： Process for forming a permanent join between two sections of fibrous material contained in a thermosetting resin matrix, said process comprising overlaying the two sections and subjecting the overlaid sections to ultrasonic welding to form a permanent join between the two sections, wherein there is no significant change in the sub-ambient Tg of the fibrous material contained in the thermosetting resin matrix in the region of the permanent join.

摘要： The present invention defines a pultrusion apparatus. The apparatus comprises a portion for receiving fibres, a portion for injecting resin into the fibres, a portion for impregnating the resin injected fibres, and a portion for shaping the impregnated fibres, wherein the fibres, following their passage through the receiving portion, converge in the resin injection portion to receive the resin and the resin flows outwards following injection as the fibres progress from the injection portion through the impregnation portion.
