Composite armor plate and armored car with same

Abstract

The invention provides a composite armor plate and an armored car with the same. The composite armor plate comprises a ceramic panel, a bulletproof armor plate, a sandwich layer and a coating layer, wherein the ceramic panel is a sheet body formed by splicing a plurality of ceramic modules, the bulletproof armor plate is fixedly arranged on one side of the ceramic panel, the sandwich layer is arranged between the ceramic panel and the bulletproof armor plate and is made of metallic foam materials, and the coating layer is coated to the surface of the other side of the ceramic panel. Accordingto the composite armor plate in the embodiment, the high strength and stiffness are achieved, the self protection stage is provided, and installing and detaching are facilitated.

Description

Technical field [0001] The present invention relates to the technical field of armored vehicle manufacturing, and more specifically, to a composite armor plate and an armored vehicle having the same. Background technique [0002] As the anti-terrorism situation intensifies, the military and police parties require that the protective vehicles should meet a higher level of safety, and have both rapid response capabilities and medium- and long-range maneuverability, and comprehensive performance requirements for vehicle body safety, lightweight and high mobility. taller and taller. The traditional protective steel plate increases the protection level by increasing the thickness, but the weight gain of the whole vehicle is large, which is difficult to meet the needs of lightweight and high mobility. Because of its low density and high modulus, ceramics hardly lose their hardness at high temperatures, making it one of the hottest bulletproof armor materials in recent years. Under th...

Problems solved by technology

Under the high-speed bombardment of projectiles, firstly, the high hardness of ceramics can passivate, deform or even break the projectile. After that, there will be sharp friction between ceramic fragments and projectiles, and the fragments will even splash back. Both processes can absorb a large amount of flight kinetic energy of the projectile; at the same time For armor-piercing incendiary bombs with high protection level, it can well resist the damage to the car body caused by the high temperature generated at the moment of impact, but due to the shortcomings of ceramics, such as poor plasticity and low fracture strength, it cannot be used as a separate armor so far.

Compared with traditional solid metal materials, metal foam materials have many unique and excellent properties due to the large number of pores inside and the characteristics of metal and air bubbles, but their own strength and stiffness are low, and they are not suitable for Used alone as a structural member
