Multi-scale multi-shape ceramic phase reinforced aluminum-based anti-ballistic structure composite material and preparation method thereof

[0018] Specific Embodiment 1: In this embodiment, a multi-scale and multi-shape ceramic phase-reinforced aluminum-based ballistic-resistant structural composite material is composed of close-packed spheres, close-packed cylinders, aluminum-containing materials and ceramic powder fillers, in which close-packed spheres serve as On the facing surface, close-packed cylinders are used as supports for close-packed spheres; the aluminum-containing material is aluminum or aluminum alloy; the bulk density of the ceramic powder filler is 45% to 60%; the multi-scale and multi-shape ceramic The overall fraction of the ceramic phase in the phase-reinforced aluminum-based ballistic structure composite material is 70-95%.

[0019] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the close-packed cylinders are cylinders with circular arcs on the end faces, with a diameter of 2-30mm and an aspect ratio of 0.3-5; The diameter of the volleyball is 1-30mm. Others are the same as in the first embodiment.

[0020] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the bulk density of the ceramic powder filler is 55%; the close-packed cylinders are B 4 C ceramic cylinder or SiC ceramic cylinder, the close-packed spheres are B 4 C sphere or SiC sphere, the ceramic powder is B4C powder or SiC powder, and the close-packed cylinders, close-packed spheres and ceramic powder are the same or different ceramics. Others are the same as in the first or second embodiment.
