The invention discloses a carbide ceramic-copper bicontinuous phase composite material with an interpenetrating network structure and a preparation method of the carbide ceramic-copper bicontinuous phase composite material. The material comprises the following components in percentage by volume: 40-60% of carbide ceramic and the balance of copper or copper alloy. The carbide and the metal phase copper or the alloy thereof are distributed in a three-dimensional continuous network mode and are of a network cross structure in space. The preparation method comprises the following steps: preparing a porous metal carbide preform by adopting a solid and gas double-carbon-source carbon thermal reduction method of a metal oxide, and carrying out copper or copper alloy pressureless infiltration to obtain a carbide-copper-based bicontinuous phase composite material, so as to obtain the three-dimensional interpenetrating network bicontinuous phase composite material with two uniformly distributed phases.
