Light impact-resistant protection plate

Abstract

The invention discloses a light impact-resistant protection plate. The light impact-resistant protection plate comprises a ceramic layer, a ceramic-aluminum gradient layer which is jointed with the ceramic layer and foam aluminum buffer layers , wherein the side, jointed with the ceramic layer, of the ceramic-aluminum gradient layer is a first side; the side, jointed with the foam aluminum buffer layers, of the ceramic-aluminum gradient layer is a second side; and from the first side to the second side, the content of ceramic in the ceramic-aluminum gradient layer is gradually decreased to 0% from 100%, and the content of metallic aluminum is gradually increased to 100% from 0%. The weight of the light impact-resistant protection plate is obviously lowered; gradient gradual transition is realized at joint positions of various materials in the impact-resistant protection plate due to the ceramic-aluminum gradient layer, so that defects of stress concentration and cracking which easily happen at a interface between the ceramic and the metallic aluminum under a high impact load in the prior art are overcome. The invention further discloses a manufacture method for the light impact-resistant protection plate.

Description

technical field [0001] The invention relates to the technical field of protective armor material manufacturing, in particular to a lightweight impact-resistant protective plate that can resist high-speed shock wave damage while avoiding damage caused by tensile wave stretching. Background technique [0002] Protective armor materials are widely used, such as explosion-proof clothing, armored vehicles and tanks. Taking tanks as an example, the current tank protective armor is generally made of high-strength steel plates. With the continuous improvement of armor performance requirements, armor materials are gradually becoming High-strength, lightweight ceramics and composite materials are developing. [0003] The existing ceramics and composite materials are used as armor, and there are mainly the following technical problems: [0004] (1) Ceramics and composite materials are used as armor, and an inner lining must be arranged inside the structure to dissipate the energy of t...

AI Technical Summary

Problems solved by technology

[0004] (1) Ceramics and composite materials are used as armor, and an inner lining must be arranged inside the structure to dissipate the energy of the shock wave. tearing, so the inner lining may have a greater destructive power to the inside of the structure; (2) To ensure that the personnel inside the structure can withstand the shock wave effect, a sufficiently thick inner lining must be set, which will cause the space inside the structure greatly reduced
