Abstract

The present invention refers to a method for manufacturing carbon fiber panels stiffened with omega stringers for the construction of aircraft structures (5), such as fuselage sections, wing panels, etc. One tubular pressure member (1) is provided for each omega stringer (6) of the structure (5) to be manufactured, wherein the tubular pressure member (1) is configured with the shape of the omega stringer. Each tubular pressure member (1) is enclosed between the omega stringer and part of the laminate (7), and autoclave pressure is applied to the interior of the tubular pressure member (1), so that the tubular pressure member is used to consolidate the omega stringers (6) and/or part of the laminate (7) from the interior of these two elements, while these two elements are being co-cured or co-bonded in an autoclave. Imperfections on those internal surfaces such as resin wrinkles of the structure are reduced.
