Abstract
Procédé de fabrication d'une pièce de révolution en matériau composite et moule d’injection Un procédé de fabrication d'une pièce de révolution en matériau composite comprend:- l’enroulement d’une texture fibreuse sur un mandrin (110) d’un moule d’injection (100) de manière à former une préforme fibreuse (20), ,- le bridage de la préforme fibreuse par positionnement d’un élément de maintien (300) sur la surface exposée de la texture fibreuse,- la découpe de la préforme fibreuse (20) en aval de l’élément de maintien (300), - la fermeture du moule d’injection (100) par une pluralité de secteurs angulaires (1201, 1202, 1203, 1204, 1205, 1206), - l’injection d’une résine dans la préforme fibreuse (20),- la transformation de la résine en matrice. L’élément de maintien (300) comprend un talon (310) en contact avec la texture fibreuse, le talon étant maintenu en position lors de la fermeture du moule (100) par des premier et deuxième secteurs angulaires adjacents (1201, 1206). Figure pour l’abrégé : Fig. 5.
