Title (EN) DEVICE FOR PRODUCING A PREFORM HAVING AT LEAST ONE LONGITUDINAL SEGMENT OF DECREASING THICKNESS, AND DEVICE FOR POSITIONING AND COMPACTING SAID PREFORM
(FR) DISPOSITIF DE REALISATION D'UNE PREFORME COMPORTANT AU MOINS UN TRONCON LONGITUDINAL D'EPAISSEUR DECROISSANTE, ET DISPOSITIF DE POSITIONNEMENT ET DE COMPACTAGE DE CETTE PREFORME
Abstract: front page image
(EN)The invention relates to a method for producing a preform (P) which is formed by a stack of reinforcing layers of fibrous structure and which comprises at least one longitudinal segment (2) of decreasing thickness. According to the invention, the method comprises the following steps consisting in: pre-compacting the preform (P1, P2) to a pre-determined intermediate compression level with respect to the final compression level, assembling the layers of each longitudinal segment of decreasing thickness (2) along tufting lines formed over most of the surface of the longitudinal segment, and compacting the pre-compacted preform in order to obtain the final compression ratio.
(FR)L'invention concerne un procédé de réalisation d'une préforme (P) formée d'un empilage de couches de renfort à structure fibreuse et comportant au moins un tronçon longitudinal (2) d'épaisseur décroissante. Selon l'invention, on pré-compacte la préforme (P1, P2) à un niveau de compression prédéterminé intermédiaire du niveau de compression final, on assemble les couches de chaque tronçon longitudinal d'épaisseur décroissante (2) par des lignes de piquage formées sur la majeure partie de la surface du dit tronçon longitudinal, et on compacte la préforme pré-compactée de façon à obtenir le taux de compression final.
