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).
