Abstract

L'invention concerne un procédé de réalisation d'une pièce comportant un profil creux en matériaux composites comprenant les étapes suivantes : formation du profil creux en matériaux composites de manière à intégrer un élément dilatable adapté pour occuper, une fois dilaté, un espace vacant dans le profil creux ; compactage (Eg) depuis l'extérieur de la pièce ; compactage (Eh) depuis l'intérieur de la pièce par dilatation de l'élément dilatable de manière différée par rapport au compactage de l'extérieur de la pièce. L'invention concerne également une pièce obtenue à partir du procédé.
