Abstract: The present disclosure relates to the field of ceramics, and discloses a metal-based aluminum nitride composite material. The composite material includes an aluminum nitride ceramic skeleton and a metal filling at least part of pores of the aluminum nitride ceramic skeleton. The aluminum nitride ceramic skeleton contains aluminum nitride and CuAlO2, and the aluminum nitride ceramic skeleton has a porosity of 20 to 40 percent. The present disclosure further discloses a method for preparing the metal-based aluminum nitride composite material and the metal-based aluminum nitride composite material obtained by the method. A CuAlO2 substance is formed in the aluminum nitride ceramic skeleton obtained in the present disclosure.
