The invention belongs to the field of novel materials and in particular relates to a novel tungsten carbide composite material and a preparation method thereof. In order to solve the problems that an existing tungsten carbide composite material cannot meet the requirements of high strength, high wear resistance and low viscosity easily, the invention provides the novel tungsten carbide composite material which comprises the following raw materials in parts by weight: 80-82 parts of WC, 4-6 parts of Al2O3, 5-8 parts of ZrO2, 2-4 parts of cobalt, 3-6 parts of germanium dioxide and 3-5 parts of tungsten powder. The invention also provides a preparation method of the composite material. The preparation method comprises the following steps: firstly, compounding tungsten carbide and tungsten powder; and then adding other raw materials to compound. The WC composite material provided by the invention is Al2O3 and ZrO2 ceramic enhanced WC composite material, has very high hardness, wear resistance and oxidation resistance as well as relatively good toughness, and is suitable for being used as a tool, a drill or a mould material. The novel tungsten carbide composite material provided by the invention adopts a simple method, is easily available in raw material, low in cost and suitable for being popularized and used.
