The invention discloses a C/SiC ceramic matrix composite and metal mixed material. An interlayer structure is formed by C/SiC ceramic matrix composites and metal shell layers. The C/SiC ceramic matrix composite and metal mixed material is characterized in that one C/SiC composite layer and one metal layer are combined into one group, the groups are alternately arranged for 5-10 times of circulation, and the C/SiC composites serve as the outermost layers. A metal coating in graded distribution along the internal direction of a ceramic matrix is arranged on the surface, contacting with the corresponding metal sheet, of each C/SiC composite. The C/SiC ceramic matrix composite and metal mixed material integrates advantages of the ceramic matrix composites and the metal materials, so that toughness thereof is improved remarkably, notch sensitivity is reduced greatly, and material strength and tenacity are improved greatly.
