Tungsten Copper Fine-grain Liner Fabricating Process (1/2)

With the development of military modernization, anti-missile capability has been greatly improved in a number of armored tanks, armored vehicles and so on. As it is now already have a high anti-missile capability reactive armor scaly, lean axle loads armor, ceramic composite armor, explosive reactive armor, which gives the more severe challenges to anti-armor weapons. The combination of shaped charge and precision guidance is the most effective anti-armor weapon, and the liner is key component of the shaped charge, whose performance will directly affect the jet armor penetration capability and stability.

So the new material for liner has become the hotspot of related researchers and scholars. Research focused on how to enhance the ductility of the material, increase the density of the material and refine the grain structure. The ductility enhancement helps form long projectile, thereby increasing the penetration depth; the density increases will enhance the impact force; refine the grain structure is conducive to increase the length of the jet. Due to the single component, traditional liner is not sufficient to meet the performance requirements today. With further research, the liner made by composite material appears. It is combining with a variety of different properties of metals or alloys to meet the design requirements liner. Compared with single metal liner, it has many advantages, such as high energy conversion efficiency, high energy efficiency, more reasonable absorption mechanism and excellent armor performance, which is the inevitable trend of liner development.
