Abstract

A multi-scale ceramic reinforced aluminum-matrix composite material containing close-packed bodies and a preparation method thereof. The invention relates to a multi-scale ceramic-reinforced aluminum-based composite material containing close-packed bodies and a preparation method thereof. The invention aims to solve the problems of poor anti-ballistic performance of traditional homogeneous aluminum matrix composite materials and low volume fraction of ceramics in bulletproof aluminum matrix composite materials. The material is composed of ceramic close-packed body, aluminum-containing material and ceramic powder filler. Method: Close-packed bodies are densely packed in the mold; 2. Ceramic powder fills the gap between the cylinders; 3. Cold pressing and preheating to prepare the prefabricated body; 4. Melting aluminum liquid; Pressing and demoulding to obtain composite materials. The ceramic content reaches 65-93vol.%, which has excellent anti-ballistic properties. The invention is used in the field of armor protection.

Description

technical field

[0001] The invention relates to a multi-scale ceramic reinforced aluminum-based composite material containing close-packed bodies and a preparation method thereof. Background technique

[0002] With the development of science and technology, the power of anti-armor weapons is increasing day by day, and the requirements for armor protection are getting higher and higher. Improving the protective effect simply by thickening the armor protection layer is bound to seriously affect the combat mobility and rapid response capabilities of the weapon system. At present, the mainstream armor structure is ceramic composite armor, and the structure is ceramic panel + metal backplate. In this structure, the wave impedance difference between the ceramic and metal interfaces is too large, resulting in a large reflected stretching wave, and the ceramic is severely broken, which affects the protection ability of the ceramic composite armor structure. It is necessary to deve...
