Abstract: There is disclosed a cutting mechanism for severing elongate fibre reinforcement material in composite material lay-up equipment, the cutting mechanism comprising a cutting element and a counteracting element which cooperate to sever fibre reinforcement material extending through the nip between them, the cutting element being mounted on an elongate arm which is pivotable about a pivot axis A spaced from the nip, to displace the cutting element relatively to the counteracting element to perform a cutting stroke, the mechanism further comprising guide means arranged to guide the fibre reinforcement material through the nip in a feed direction transverse to the pivot axis A, and an actuation device for driving the elongate arm in a cutting stroke, the actuation device acting on the elongate arm at a position away from the cutting element. There is also provided composite material lay-up equipment comprising the cutting mechanism.

Abstract: There is disclosed a method of manufacturing a composite component, the method comprising laying-up a plurality of successive plies of composite material to produce a pre-form (12) for the component in a lay-up procedure, wherein a portion of each ply of composite material is heated to at least a threshold temperature of 45° C. during a period of the lay-up procedure.
