Abstract

The invention provides a gradient ceramic column reinforced aluminum-based composite armor plate and a preparation method thereof. The composite armor plate comprises ceramic columns, an aluminum alloy substrate and an aluminum alloy melt infiltration body; the aluminum alloy substrate comprises at least three layers, the upper layer and the lower layer are complete aluminum alloy plates, and the middle layer is subjected to double-sided hole milling according to designated positions and apertures; the ceramic columns are arranged on the middle-layer aluminum alloy substrate in parallel or in a staggered manner and are covered by the upper-layer aluminum alloy substrate and the lower-layer aluminum alloy substrate to form a framework; and the aluminum alloy melt infiltration body is used for filling gaps in the framework, connecting the substrate and realizing three-dimensional constraint on the ceramic columns. The gradient ceramic column reinforced aluminum-based composite armor plate provided by the invention is relatively excellent in multi-shot strike resistance and integrity, does not have an obvious weak area, and has a bright application prospect in the field of armor protection.

Description

technical field [0001] The invention relates to the technical field of armor, in particular to a gradient ceramic column reinforced aluminum-based composite armor plate and a preparation method thereof. Background technique [0002] The research on armor protection at home and abroad mainly focuses on the optimization of the two main lines of material and structure, aiming to achieve the development goal of "three highs and one low", that is, the unity of high strength, high hardness, high toughness and low density. [0003] Traditional homogeneous armor, such as armor steel and armor titanium, mainly achieves the improvement of protection performance by increasing the thickness, which greatly reduces the mobility of armored vehicles. The ceramic layered composite armor with sandwich structure has great advantages in reducing surface density and improving protection coefficient, and has the characteristics of simple processing technology and strong structural design. With t...
