摘要： The invention relates to a method for manufacturing a laminated product having a variable thickness and consisting of a heat-treated aluminum alloy, in which a variation in thickness of at least 10% lengthwise, between the thickest portion and the thinnest portion, is achieved by heat-rolling, the resulting laminated product having a variable thickness is solution heat-treated and soaked, and the laminated product, which has a variable thickness and which is thus solution heat-treated and soaked, is stress-relieved by controlled traction with a permanent deformation of at least 1 % in the thickest portion prior to natural or artificial aging. The products obtained according to the invention have a mechanical resistance that is improved by at least 5% in the thinnest portion and an improvement in stiffness of at least 15% in the thickest portion. The products according to the invention are useful in particular for producing lower or upper wing skins for an aircraft because the "buy to fly" ratio and the properties are simultaneously improved.
