High-impact-resisting composite preparation method

The invention discloses a high-impact-resisting composite preparation method. The 3D printing technology is used, two materials of high-strength metal and high-toughness metal are adopted to interweave and stack a first layer pile and a third layer pile which are of the same structure, so that a prepared high-impact-resisting composite has the strength of the high-strength metal, better energy absorbing and high-impact-resisting performance of the high-toughness materials. A second layer pile is arranged between the first layer pile and the third layer pile, each layer pile is composed of a plurality of pile layers, and after each pile layer is completed, each pile layer is rotated by 90 degrees around the Z axis to compensate for the defects of a high starting point and a low end point inthe 3D printing process, so that a plane is finally obtained. The metal piling direction changes to further enable the two metals to form an interweaving structure in a three-dimensional space to enhance the performance of t
