A kind of composite material, tungsten wire-CVD tungsten was fabricated by winding tungsten wire on the substrate periodically in the CVD process using the homemade CVD device. The density, composition and micro-hardness were tested and analyzed; the crushing strength was calculated according to crushing test; the tensile and bending curves were obtained according to tensile test and three-point bending test. The results show that the dense coating without holes can be obtained when the chemical reaction temperature is controlled at 550 oC and the flows of WF6 and H2 are controlled at 2 g/min and 1 L/min, respectively. Compared with the CVD tungsten samples without wound tungsten wire under the same process conditions, the tungsten wire-CVD tungsten composite materials still possesses high purity and density, the similar micro-hardness, but the crushing strength, the tensile strength and the bending strength are improved greatly
