Abstract
A drape forming apparatus for use in forming a composite structure. The apparatus includes a forming tool including an upper forming surface and at least one side forming surface that extends from the upper forming surface. The forming tool receives at least one layer of composite material over the upper forming surface. The apparatus also includes a flange forming device including a tray coplanarly aligned with the upper forming surface when in a first operating position. The tray is configured to receive a flange portion of the at least one layer of composite material. A pressurized bladder extends over the forming tool and the tray. The pressurized bladder is configured to induce a first force against the tray such that the tray rotates about a pivot line, and such that the flange portion is withdrawn from the tray and draped over the at least one side forming surface.
