    摘要: The invention relates to a method, and wings (100) for an aircraft obtained by said method, for assembling a casing structure (100) including basic parts (230, 240, 321) that are assembled according to a sub-structure of stiffeners (230, 240), and skins (321). The sub-structure and the skins consist of a polymer matrix composite material. Said method includes steps involving: a. sizing the casing structure on the basis of the biasing that said structure is subjected thereto, and for an adhered assembly; b. obtaining a mapping of the biasing of said structure and defining a first biasing threshold on the basis of probability of damage to the structure; c. assembling the sub-structure and the skins by adhesion; and d. applying counter-stratification (350) covering the assembled basic parts, in the areas of the assembled casing structure where the first biasing threshold is reached.
