| description | The invention relates to a method for manufacturing a part made of a composite material including the following steps: pre-compacting, into a predetermined shape, a mixture of a first heat-setting resin with discontinuous long fibres such as to form a first preform (220), pre-cooking the first preform (220) until an intermediate conversion stage of the first heat-setting resin corresponding to a solidification of said first resin, moving the first preform (220) towards a second preform (210) including a fibrous texture of continuous fibres impregnated with a second heat-setting resin, polymerising the first and second preforms (220, 210) such as to form a part made of a composite material including a body of composite material including a reinforcement of continuous fibres consolidated by an organic fibre provided with a portion made of a composite material including a reinforcement made of discontinuous long fibres consolidated by an organic matrix.
Procédé de fabrication d'une pièce en matériau composite comprenant les étapes suivantes: pré-compactage suivant une forme déterminée d'un mélange d'une première résine thermodurcissable avec des fibres longues discontinues de manière à former une première préforme (220), pré-cuisson de la première préforme (220) jusqu'à un stade de conversion intermédiaire de la première résine thermodurcissable correspondant à une solidification de ladite première résine, accostage de la première préforme (220) avec une deuxième préforme (210) comprenant une texture fibreuse de fibres continues imprégnées avec une deuxième résine thermodurcissable, polymérisation des première et deuxième préformes (220, 210) de manière à former une pièce en matériau composite comprenant un corps en matériau composite comprenant un renfort en fibres continues consolidé par une matrice organique muni d'une portion en matériau composite comprenant un renfort en fibres longues discontinues consolidé par une matrice organique. |
