Abstract: There is disclosed a method of manufacturing a composite blade, and the composite blade. The method comprises a lay-up operation comprising laying up fibre reinforcement material on an untwisted lay-up surface to make a blade pre-form and a forming operation comprising forming the blade pre-form to introduce twist in the blade pre-form.

Abstract: There is disclosed a method of manufacturing a composite component. A preform for the component is laid-up on a lay-up tool so that a first surface of the preform conforms to a lay-up profile of the tool. The preform is transferred to a forming tool comprising opposing first and second forming surfaces, each having a near net shape profile corresponding to a respective side of the component. The preform is formed in the forming tool to a near net shape of the component. The preform has a preform bulk in excess of the near net shape of the component prior to forming, and the lay-up profile is offset relative to the near net shape profile of the first forming surface to accommodate a proportion of the preform bulk. Accordingly, both the first surface and an opposing second surface of the preform displace during forming to conform to the respective near net shape profiles of the forming surfaces.
