Title (EN) METHOD AND EQUIPMENT FOR PRODUCING A PART BY INJECTING RESIN INTO A WOVEN FIBRE PREFORM
(FR) PROCEDE ET OUTILLAGE DE FABRICATION D'UNE PIECE PAR INJECTION DE RESINE DANS UNE PREFORME EN FIBRES TISSEES
Abstract:
(EN) A method for producing a part by injecting resin (202) into a woven fibre preform (200), comprising the steps of: c) shaping the preform, d) forming the preform, and e) injecting resin into the preform and moulding, the step e) being carried out by means of equipment (100) comprising a mould (102), a countermould (106), and resin injecting means, characterised in that the step e) comprises the substeps of: e1) partially opening the equipment (100), e2) injecting resin into the equipment, e3) closing the equipment, and e4) pressurising and heating the impregnated preform (200) between the mould (102) and the countermould (106).
(FR) Procédé de fabrication d'une pièce par injection de résine (202) dans une préforme (200) en fibres tissées, comprenant les étapes de : c) mise en forme de la préforme, d) formage de la préforme, et e) injection de résine dans la préforme et moulage, l'étape e) étant réalisée au moyen d'un outillage (100) comportant un moule (102), un contre-moule (106), et des moyens d'injection de résine, caractérisé en ce que l'étape e) comprend les sous-étapes de : e1) ouverture partielle de l'outillage (100), e2) injection de résine dans l'outillage, e3) fermeture de l'outillage, et e4) mise sous pression et chauffage de la préforme (200) imprégnée entre le moule (102) et le contre-moule (106).
