This invention discloses a double-through-structure bimetallic composite material, its preparation method, and its application. The composite material comprises a stainless steel porous framework and an aluminum-based composite material filler; the aluminum-based composite material is uniformly filled within the stainless steel porous framework structure; the aluminum-based composite material comprises AlSi. X Mg (0 ≤ x ≤ 10) and B4C. The composite material of this invention consists of spherical AlSi... X This composite material is prepared by mixing Mg (0 ≤ x ≤ 10) alloy powder and B4C powder in a specific ratio and then sintering. It exhibits excellent energy absorption properties, high strength, and impact resistance, making it suitable for applications in aerospace, automotive, and protective equipment. The production method is simple, with a short production cycle and high efficiency. Furthermore, this material significantly improves the deformation resistance and impact resistance of traditional stainless steel and aluminum alloys under impact conditions, thereby broadening its application range in industrial fields.
