Abstract

L'invention a pour objet un procédé de fabrication d'une pièce en matériau composite comportant, dans l'ordre, les étapes de : - réalisation d'une préforme (34) en empilant des plis de fibres sur un moule (38), - réalisation d'au moins un évidement (42) dans la préforme (34) correspondant à au moins une des découpes de la pièce, - consolidation de la préforme (34) pour obtenir la pièce, et - démoulage de la pièce. La présence des évidements (42) dans la préforme (34) lors de l'étape de consolidation permet de rendre moins aléatoire le retour élastique si bien qu'il est plus facile de le quantifier sans avoir besoin de recourir à des essais réels.The subject of the invention is a method of manufacturing a part made of composite material comprising, in order, the steps of: - production of a preform (34) by stacking plies of fibers on a mold (38), - production of at least one recess (42) in the preform (34) corresponding to at least one of the cutouts of the part, - consolidation of the preform (34) to obtain the part, and - release of the part. The presence of the recesses (42) in the preform (34) during the consolidation step makes it possible to make the elastic return less random so that it is easier to quantify it without having to resort to real tests.
