    The invention discloses a carbon-copper composite material for a pantograph of a high-speed train and a preparation method of the carbon-copper composite material, wherein the carbon-copper composite material comprises a low-density carbon-carbon composite material, and a boron nitride interface layer is deposited on the low-density carbon-carbon composite material through chemical vapor deposition. The carbon-carbon composite material and the boron nitride interface layer are subjected to vapor-phase titanizing to form a titanium carbide and titanium nitride mixed interface layer, and then vapor-phase copper infiltration is performed to form a copper phase; the boron nitride interface layer has good mechanical property and strong oxidation resistance, so that the oxidation resistance of the product can be effectively enhanced; TiN is higher than TiC in oxidation resistance, TiC is higher than TiN in hardness, and the TiN and TiC mixed interface layer combines the advantages of TiN and TiC, so that the comprehensive performance of the material is improved; and the wettability of the TiC and TiN mixed interface layer and the copper phase is good, and the problem that the carbon-copper bonding performance is poor is solved through the interface layer.
