COMPOSITE MATERIAL, PREPARATION METHOD, HOUSING, HOUSING PREPARATION METHOD AND ELECTRIC MOTOR

Provided in the present application are a composite material, a preparation method, a housing, a housing preparation method and an electric motor. The composite material contains resin, fibers and a metal alloy, wherein the fibers comprise conductive fibers. Therefore, by means of adding the conductive fibers and the metal alloy in the composite material, the metal alloy is melted and directionally gathered at conductive-fiber node positions during the process of forming the composite material, such that a fiber three-dimensional network framework is formed, thereby effectively reducing the electrical resistance and thermal resistance at the conductive-fiber node positions; furthermore, the fracture toughness of the composite material is also enhanced, thereby greatly increasing the electrical conductivity and thermal conductivity of a product prepared from the composite material while ensuring that the product has excellent surface smoothness, compactness and mechanical strength.
