Zusammenfassung:COMPOSITE STRUCTURES WITH STIFFENERS AND METHOD OF MAKING THE SAME A method for assembling a stiffened composite structure (28) includes a step (30) of positioning a plurality of dry fibres (27) along a first side (34) of a pre-preg composite laminate skin element (20) wherein the pre-preg composite laminate skin element (20) is dimensionally changeable. The method further includes a step (44) of positioning an interlayer (38) between the plurality of dry fibres (27) and the first side (34) of the pre-preg composite laminate skin element (20) and a step (52) of infusing the plurality of dry fibres (27) with a resin forming a plurality of infused fibres. The method also includes a step (58) of co-curing the pre-preg composite laminate skin element (20) and the plurality of infused fibres. ,38
