The invention relates to a preparing method for an ethanol-dispersed tungsten carbide silicon carbide and carbon fiber friction material. The preparing method is characterized in that a graphited carbon fiber blanket with the density ranging from 0.1 g/cm<3> to 1.8 g/cm<3> is subjected to carburizing treatment, padding treatment through ethanol-dispersed tungsten carbide, silicon carbide depositing treatment and buried siliconizing treatment in sequence, then nitriding treatment is carried out in a nitrogen atmosphere, and the ethanol-dispersed tungsten silicon carbide and carbon fiber friction material is obtained. According to the preparing method, the fiction material is prepared by performing the steps of carburizing, tungsten carbide padding, silicon carbide depositing, buried siliconizing, nitriding and the like on the graphited carbon fiber blanket, and the prepared friction material is high in strength, tenacity and friction performance and adapts to various weather conditions.
