Abstract

Procédé de fermeture d’un moule d’injection utilisant des plis sacrificiels anti-pincement Un Procédé de fermeture d’un moule d’injection (100) pour la fabrication d'une pièce de révolution en matériau composite, le moule comprenant un mandrin (110) supportant une préforme fibreuse (20) et une pluralité de secteurs angulaires (120) comprenant une base annulaire (121) destinée à venir en contact de la texture fibreuse (20), la base annulaire s’étendant entre des premier et deuxième bords latéraux (124, 125) suivant une direction circonférentielle (DC). Le procédé comprend le positionnement et la fixation successifs des secteurs angulaires (120) sur le mandrin (110), la base annulaire (121) de chaque secteur compactant la portion de préforme fibreuse présente en vis-à-vis, les bords latéraux (124, 125) de la base annulaire (121) de chaque secteur angulaire (120) étant en contact avec les bords latéraux (124, 125) de la base annulaire (121) des secteurs adjacents. Avant le positionnement et la fixation des secteurs angulaires sur le mandrin, des plis fibreux sacrificiels (200) sont placés sur la surface exposée de la préforme fibreuse (20), chaque pli fibreux sacrificiel (200) couvrant une zone de la préforme fibreuse située en regard d’une zone de jonction entre deux bords latéraux (124, 125) de la base annulaire (121) de deux secteurs angulaires adjacents 120). Figure pour l’abrégé : Fig. 4.
