Beschreibung
Zusammenfassung:	The invention relates to a method for manufacturing a composite material (8) comprising a metal matrix reinforced by a carbon reinforcement, characterised in that the method is a continuous extrusion method which comprises friction-heating of a mixture (7) obtained from a mixture of powders comprising a metal-matrix powder and a carbon-reinforcement powder, by means of a movable extrusion wheel (2), in a passage formed between a groove (2a) of the wheel (2) and a stationary element referred to as shoe (3), followed by carrying the mixture (7) thus heated towards an extrusion die (4). L'invention a pour objet un procédé de fabrication d'un composite (8) comprenant une matrice métallique renforcée par un renfort de carbone, caractérisé en ce que le procédé est un procédé d'extrusion en continu comprenant l'échauffement par friction d'un mélange (7) obtenu à partir d'un mélange de poudres comprenant une poudre de matrice métallique et une poudre de renfort de carbone, à l'aide d'une roue d'extrusion (2) mobile, dans un passage formé entre une gorge (2a) de la roue (2) et un élément fixe appelé sabot (3), puis l'acheminement du mélange (7) ainsi chauffé vers une filière d'extrusion (4).
