Abstract: front page image
(EN)The invention relates to a method for producing structures from composite materials, which are formed by two sub-components of the same material. The invention is characterised in that it comprises the following steps consisting in: obtaining a first sub-component (13), in particular a skin; obtaining a tool (15) which is made from a composite material in the precured state and which is used to produce the second sub-component (17), in particular a stiffener; positioning the tool (15) on the first sub-component (13); applying the pre-impregnated composite material (21) against the tool (15) in order to form the second sub-component (17); and strengthening the structure using a process consisting in curing the assembly that was produced during the previous steps under suitable pressure and/or temperature conditions.
(ES)Proceso para fabricar estructuras de materiales compuestos formadas por dos subcomponentes del mismo material, caracterizado porque comprende los siguiente pasos: proporcionar un primer subcomponente (13) particular- mente una piel; proporcionar un útil (15) realizado con un material compuesto y en estado precurado para la fabricación del segundo subcomponente (17), particularmente un rigidizador; posicionar dicho útil (15) sobre dicho primer subcomponente (13); aplicar material compuesto preimpregnado (21) sobre dicho útil (15) para formar el segundo subcomponente (17); consolidar la estructura de material compuesto mediante un proceso de curado del conjunto resultante de los pasos anteriores bajo condiciones apropiadas de presión y/o temperatura.
(FR)L'invention concerne un procédé de fabrication de structures de matériaux composés formées de deux sous-composants du même matériau, se caractérisant par les étapes suivantes: l'utilisation d'un premier sous-composant (13), en particulier une peau; l'utilisation d'un outil (15) formé à partir d'un matériau composé et à l'état pré-séché pour la fabrication du second sous-composant (17), en particulier un élément de renforcement de la rigidité; le positionnement dudit outil (15) sur ledit premier sous-composant (13); l'application d'un matériau composé pré-imprégné (21) sur ledit outil (15) pour former le second sous-composant (17); la consolidation de la structure de matériau composé au moyen d'un processus de séchage de l'ensemble obtenu dans les étapes antérieures dans des conditions appropriées de pression et/ou de température.
