CA 2734083
The invention relates to a method for making a part made of a composite material with a metal matrix, characterised in that the method includes the steps of: providing, on a preform of the part to be made, at least one assembly of reinforcing fibres, said fibres being previously coated with at least one metal or metal alloy; heating the assembly to a temperature sufficient for diffusing the metal particles surrounding the fibre; after cooling, releasing the part made of the preform and withdrawing the latter.
La présente invention se rapporte à un procédé de fabrication d'une pièce en matériau composite à matrice métallique caractérisé en ce qu'il comprend les étapes visant à: disposer sur une préforme de la pièce à réaliser au moins un ensemble de fibres de renforts, lesdites fibres étant pré-enrobées d'au moins un métal ou alliage métallique; porter l'ensemble à une température suffisamment élevée pour permettre la diffusion des parties métalliques enrobant la fibre; après refroidissement, démouler la pièce formée de la préforme et retirer cette dernière.
