Abstract:
There is disclosed a self-heating tool (10) for manufacturing a composite component, comprising: a support structure (24); a mandrel (26) onto which composite material can be applied; a heater (58) for heating the mandrel (26) during a curing operation; and a plurality of extendible support members (28) extending between the support structure (24) and the mandrel (26) to support the mandrel (26). Each extendible support member (28) is configured to change in length in response to thermal expansion of the mandrel (28) during a curing operation. A method of manufacturing a composite component using a self-heating tool is also disclosed.
Abstract:
There is disclosed a method of forming a composite component having a curved body and an integral flange from a pre-form (200) using forming apparatus comprising: a tool (102) comprising a curved body portion (104) having a lay-up surface (110) and a forming assembly (105) comprising a plurality of forming elements (106) each having a lay-up surface (120) and a primary flange-forming surface (122); and a plurality of filler elements (107) each having a secondary flange-forming surface (156). The method comprises: providing a pre-form (200) over the lay-up surfaces (110, 120) of the curved body portion 104 and the forming elements (106) of the tool (102) in a layup configuration of the forming assembly (105); moving the forming elements (106) radially outwardly from the layup configuration to respective forming positions so that the forming elements (106) are circumferentially spaced apart from one another to form gaps therebetween; moving the filler elements (107) radially outwardly to respective forming positions in the circumferential gaps between the forming elements (106) so that the primary and secondary flange-forming surfaces (122, 156) form a substantially continuous flange-forming surface in a forming configuration of the forming assembly (105). Movement of the forming assembly (105) from the layup configuration to the forming configuration causes a region of the pre-form (200) to deform between the continuous flange-forming surface and a counteracting forming surface to form the integral flange of the component.
