Abstract

Procédé d’infusion d’une préforme fibreuse L’invention concerne un procédé d’infusion d’une préforme fibreuse par une résine de polycondensation comprenant au moins : A) une alimentation d’un contenant intermédiaire (13) avec une résine à une pression supérieure à la pression atmosphérique, l’alimentation comprenant au moins : A1) un transfert de la résine (20) depuis le contenant initial (11) jusqu’à un réchauffeur (12) ; A2) un chauffage de la résine par le réchauffeur ; et A3) un transfert de la résine chauffée (22) vers le contenant intermédiaire (13) ; B) une infusion de la préforme fibreuse (14) par la résine de polycondensation ainsi transférée réalisée par aspiration depuis le contenant intermédiaire lequel est maintenu à une température d’infusion supérieure ou égale à la température d’injection ; l’alimentation du contenant intermédiaire étant réalisée à une pression supérieure ou égale à 1,5 bar absolu et l’infusion étant réalisée à une pression inférieure ou égale à 0,1 bar absolu. Figure pour l’abrégé : Fig. 1.
