The invention provides a high-thermal-conductivity composite material and a preparation method thereof, and further provides the high-thermal-conductivity composite material and the preparation method from design material selection and process innovation on the basis of embedding a heat pipe structure in an aluminum panel composite material, so that the weight of the whole plate is reduced, and meanwhile, efficient heat conduction is realized. According to the high-thermal-conductivity composite material, the panel is made of the mesophase pitch-based carbon fiber reinforced resin-based composite material, the in-plane thermal conductivity of the panel at the temperature of 20 DEG C is larger than or equal to 135 W/(m.K), and high-efficiency heat conduction of the whole panel is achieved through the embedded kilowatt-level thermal conductivity aluminum-ammonia heat pipes.
