In order to improve the resistance of a carbon/carbon type composite material to oxidation, an interphase is formed between the carbon fibers of the fiber reinforcement of the material and the carbon matrix, said interphase being constituted by 1% to 20% atomic percent of silicon, at least 30% atomic percent of boron, with any balance being of carbon and/of phosphorous. The thickness of the interphase is less than 1 µm and not less than 10 nm.
