A method for manufacturing composite parts includes positioning a plurality of composite layers on an application surface formed by a plurality of tooling members and filler members on a mandrel. A part formation aid is disposed on the composite layers above each tooling member. The filler members are then removed, and the composite layers slit over the recesses. The mandrel, the tooling members, the composite layers, and the part formation aids are placed in a vacuum bag. As the bag is evacuated, each part formation aid forces the side edge of the composite layers formed by the slit around the respective tooling member, thereby forming a composite part with a desired shape, thickness, and density. In an alternate embodiment, a flanged composite panel is formed around a rectangular mandrel after positioning composite layers on an outer surface of the mandrel and an outer surface of a filler member disposed on one end of the mandrel. After removing the filler member, the flanged panel is formed and partially cured by vacuum bagging. A plurality of tooling members and filler members are then placed on the flanged panel to form an application surface. Composite layers are positioned on the application surface, and then the filler members are removed. Vacuum bagging is used to produce a plurality of stiffeners around the tooling members and directly adjacent to the flanged panel. The stiffeners and flanged panel are co-cured to produce a single and integral part.
