    CPC classification number: B29C70/542 B29C70/342

    Abstract: There is disclosed bagging apparatus (20) for bagging a pre-form (12) for a composite component on a tool (10), the apparatus (20) comprising: a bag dispenser (22) having a store (28) for a tubular vacuum bag (30); and a bag guide (36). In use, a length of tubular vacuum bag material (30) can be drawn from the store (28) radially outwardly over the bag guide (36) and over the tool (10) to form a tube around the pre-form. There is also disclosed a method of bagging a pre-form (12) for a composite component on a tool using the bagging apparatus (20).

    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.
