In the production of armored vehicles, the consumption of homogeneous thin armor plate is large, the production process is simple and the cost is low. The disadvantage is: if the treatment is too hard, it will become brittle; if the treatment is too soft, it will have weak elastic resistance and can not meet the requirements of use. But for the double hardness armor composite panels, the advantages are the hard surface and the soft backing. This can not only make the bullet resistance better than homogeneous, but also reduce the equivalent thickness of armor, reduce the weight of vehicles and improve mobility. Therefore, it is a development direction to adopt double hardness armor clad steel plate in light vehicle armor production.
The bulletproof armor plate of our assault aircraft used to be the mean plate imported from abroad. It is of high specific gravity, high strength and can not be formed, only used in the cockpit floor, fuel tank, oil cover and oil pump mouth cover and other limited parts. The development of Aeronautical light-weight bullet-proof armor will provide new composite materials with small specific gravity, high strength, good molding and bullet-proof effect for the next generation of assault aircraft.
In order to reduce casualties, it is an ideal method for armed personnel to install portable and effective protective materials, such as bullet-proof vest, in key parts of the human body.
According to the bullet-proof mechanism, the strength and toughness of materials are two equally important performance indexes for the bullet-proof armor. But for homogeneous materials, they are mutually restricted, and they are often not available. Therefore, to improve ballistic performance, any armor plate should be made of composite material.
The armor plate for armored vehicles, the composite plate for aviation and the bullet-proof vest. Henan Chinalco generally uses the explosive composite + rolling process to obtain the composite plate for armor. It is technically feasible, reliable in quality and can be used as the structural material for light armored vehicles.
Henan Chalco is usually made of Maraging steel-aluminum armor plate by explosive welding or aluminum-low carbon steel-steel armor structure material.
