Description
Technical Field
The invention relates to the technical field of composite armor, in particular to a light packaged composite armor and a manufacturing process thereof.
Background
Tanks are weaponry which is born for more than one hundred years, and the self-protection capability is always improved from the beginning of appearance. From the rivet armor of the 20 th century, to the large dip steel armor of the 40 th, to the oval turret of the 60 th, these improvements in tank protection are very limited in general. The armor is made of steel, and the equivalent armor thickness is improved only by changing the appearance, and the probability of being hit to jump eggs is increased. And the advent of composite armor began in the 80 s of the last century. Truly and fundamentally influences the development of tanks.
Composite armor is simply divided into invisible and visible. The invisible composite armor refers to the armor plate of the tank itself, which is not only steel but also other substances. What is visible is the externally hung reactive armor of modern tanks. I.e., objects resembling a brick structure, there is often explosive reactive armor. The use of composite armor has become a consensus today in the 21 st century. Also becomes a new way for the development and protection of the tank.
Most of the existing composite armor is of a double-layer or multi-layer structure such as ceramic/metal and ceramic/composite materials, and the structure meets the basic bulletproof requirement of a tank, but can not protect continuous multiple armor piercing bullets when protecting small and medium caliber armor piercing bullets, and has poor protection capability when facing high-density fire coverage.
