ABSTRACT:
A method for manufacturing a composite structure is disclosed herein. The process uses a frame and selectively pressurizable forms. The forms define the interior members of the composite structure and frames define the exterior surface of the composite structure. Composite material is wrapped around the forms and the forms and composite material are placed in the frame. Selective forms are then pressurized and the composite material is co-cured together. A single piece co-cured fuselage incorporating a plurality of stiffeners is also disclosed in the application. The stiffeners are co-cured to the fuselage and may be in various patterns. The patterns may include an iso-grid pattern, and ortho-grid pattern, and a hoop-grid pattern.
