Title (EN) RESIN INJECTION CONTROLLER, RESIN INJECTION CIRCUIT AND ASSOCIATED METHODS
(FR) REGULATEUR D'INJECTION DE RESINE, CIRCUIT D'INJECTION DE RESINE ET PROCEDES ASSOCIES
Abstract:
(EN) A resin injection controller (56, 58) for a circuit (12) for injecting resin into a mould (14) for manufacturing a composite part, in particular a turbomachine composite part, characterised in that it comprises at least one enclosure (70) that is linked to said circuit (12) and inside which a movable wall means (72) is able to move in a sealed manner, said movable wall means (72) delimiting, in said enclosure, a first cavity (74) forming a reservoir for accumulating resin and configured to be linked to at least a part (26) of said circuit (12), and a second cavity (76) configured to be linked to a pressurised fluid source (52), said movable wall means (72) being configured to be biased by the pressurised fluid supplying the second cavity (76) in order to exert pressure on the resin contained in the first cavity (74), while isolating said resin from said fluid.
(FR) Régulateur (56, 58) d'injection de résine pour un circuit d'injection de résine (12) dans un moule de fabrication (14) d'une pièce composite, notamment une pièce composite de turbomachine, caractérisé en ce qu'il comporte au moins une enceinte (70) qui est reliée audit circuit (12) et à l'intérieur de laquelle est mobile de manière étanche un moyen de paroi mobile (72), ledit moyen de paroi mobile (72) délimitant dans ladite enceinte une première cavité (74) formant un réservoir d'accumulation de résine et configurée pour être reliée à au moins une partie (26) dudit circuit (12), et une seconde cavité (76) configurée pour être reliée à une source de fluide sous pression (52), ledit moyen de paroi mobile (72) étant configuré pour être sollicité par le fluide sous pression alimentant la seconde cavité (76) afin d'exercer une pression sur la résine contenue dans la première cavité (74), en isolant ladite résine dudit fluide.
