Abstract

Circuit (100) de fabrication d’une pièce composite par moulage RTM, ce circuit comportant : - un premier réservoir (102) de stockage de résine polymérisable, - un moule (104) configuré pour recevoir une préforme fibreuse (108) et comportant un port (104a) d’entrée de résine, et - une pompe d’alimentation du moule en résine, caractérisé en ce qu’il comprend en outre : - un second réservoir (122) de stockage de fluide pousseur, et - une conduite (116) de circulation de résine et de passage d’un racleur (120) pour forcer le passage de la résine dans cette conduite, cette conduite étant reliée par une gare de départ (116a) au second réservoir, et par une gare d’arrivée (116b) audit port d’entrée du moule.
