Abstract

L'invention concerne un procédé. Le procédé comprend l'application d'une couche de matériau fibreux tressé autour d'un outil. Le procédé comprend également l'agencement d'une feuille stratifiée composite sur le matériau fibreux tressé. Le procédé comprend en outre l'application d'une couche supplémentaire de matériau fibreux tressé sur la feuille stratifiée composite pour former un longeron. Le procédé comprend en outre l'assemblage du longeron, de telle sorte que les couches de matériau fibreux tressé sont couplées de manière fixe à la feuille stratifiée composite. Le procédé consiste à retirer l'outil du longeron.
