Abstract

Procédé de fabrication d’une pièce en matériau composite L’invention concerne de fabrication d’une pièce en matériau composite comprenant les étapes suivantes : - la disposition d’une préforme fibreuse dans un moule, - une étape d’injection (E2) dans le moule d’une résine à imprégner dans la préforme fibreuse, - une étape de polymérisation (E3) de la résine pour former la pièce en matériau composite, caractérisé en ce que l’injection et la polymérisation de ladite résine sont réalisées avec une température de résine identique, cette température étant supérieure ou égale à la température d’activation de la résine. Figure pour l’abrégé : Fig. 1Method for manufacturing a composite material part The invention relates to manufacturing a composite material part comprising the following steps: - placing a fiber preform in a mould, - a step of injecting (E2) into the mold of a resin to be impregnated in the fibrous preform, - a stage of polymerization (E3) of the resin to form the part in composite material, characterized in that the injection and the polymerization of the said resin are carried out with a temperature of identical resin, this temperature being greater than or equal to the activation temperature of the resin.
