A method of manufacturing a curved element made of composite material comprises the following steps: a) preparing at least one dry, flat reinforcing layer (1) with curved fibres, b) combining a resin film (2) with the dry, flat reinforcing layer, and applying heat and pressure in controlled manner so as to bring about the infusion of the resin into the reinforcing layer and to obtain at least one layer of pre-infused material (Y), c) preparing at least one prepreg layer (31, 32) with straight fibres impregnated with resin compatible with the resin of the pre-infused material, d) superimposing the layer of pre-infused material and the prepreg layer on one another so as to obtain a layered structure (1"), and e) subjecting the layered structure, arranged on a shaped support tool (30), to a polymerization cycle so as to obtain the curved element.

L'invention porte sur un procédé de fabrication d'un élément incurvé fait de matière composite. Ce procédé comprend les étapes suivantes: a) préparer au moins une couche de renforcement plate, sèche (1) avec des fibres incurvées, b) combiner un film de résine (2) avec la couche de renforcement plate, sèche, et appliquer chaleur et pression d'une manière contrôlée de façon à entraîner l'infusion de la résine dans la couche de renforcement et à obtenir au moins une couche de matière pré-infusée (Y), c) préparer au moins une couche de pré-imprégné (31, 32) avec des fibres rectilignes imprégnées par une résine compatible avec la résine de la matière pré-infusée, d) superposer la couche de matière pré-infusée et la couche de pré-impregné l'une sur l'autre de façon à obtenir une structure feuilletée (1'), et e) soumettre la structure feuilletée, disposée sur un outil de support façonné (30), à un cycle de polymérisation de façon à obtenir l'élément incurvé.
