Methods of manufacturing a stiffening element for an aircraft skin panel and a skin panel provided with the stiffening element

摘要

A method of manufacturing a stringer for a fuselage skin panel comprises the steps of: ;preparing a pile of sheet-metal strips bent so as to have a cross-section of given shape, alternating with at least one layer of resin-impregnated fibre, and ;applying heat and pressure to the pile in a manner such as to cure the resin and set the shape. ;A composite laminated stringer is thus obtained. ;In order to manufacture a fuselage panel of composite laminated material, provided with composite laminated stringers, the resin in the stringers is cured simultaneously with the resin which is present between the metal layers of a laminate suitable for forming the outer skin.
