Abstract: Composite sections for aircraft fuselages and methods and systems for manufacturing such sections are herein. A composite aircraft panel manufacturing assembly comprises a skin, a stiffener, a tubular bladder, and at least one ply of fabric. The stiffener comprises first and second flange portions bonded to the skin. The stiffener further comprises an interior surface, spaced apart from the skin, and extending between the first and second flange portions. The tubular bladder extends longitudinally between the interior surface of the stiffener and the skin. The at least one ply of fabric extends around the bladder and is bonded to the interior surface of the stiffener and an adjacent portion of the skin between the first and second flange portions.

Abstract: Composite sections for aircraft fuselages and methods and systems for manufacturing such sections are disclosed herein. A composite section configured in accordance with one embodiment of the invention includes a skin and at least first and second stiffeners. The skin can include a plurality of unidirectional fibers forming a continuous surface extending 360 degrees about an axis. The first stiffener can include a first flange portion bonded to an interior surface of the skin and a first raised portion projecting inwardly and away from the interior surface of the skin. The second stiffener can include a second flange portion bonded to the interior surface of the skin and a second raised portion projecting inwardly and away from the interior surface of the skin. A method for manufacturing a section of a fuselage in accordance with one embodiment of the invention includes positioning a plurality of uncured stiffeners on a mandrel assembly.
