Composite/ceramic Bulletproof Plates Have Insurmountable Advantages Over Metal Bulletproof Plates!

First of all, metal armor is through the projectile impact homogenous metal armor, in the limit running through the speed near, the target plate destruction mode is mainly compressed opening pit and shear plug, the consumption of kinetic energy mainly rely on plastic deformation and punch caused by the shear function.

The utilization rate of ceramic composite armor to kinetic energy should be significantly higher than that of homogeneous metal armor.

First of all, the reaction of the ceramic target surface is divided into five processes.

1: The top of the projectile is broken into small pieces, and the broken warhead increases the area of the projectile, thus dispersing the load acting on the ceramic plate.

2: Crack on the ceramic surface in the collision zone and extend outward from the impact zone.

3: This force field with the impact area compression wave array in front of the deep into the ceramic interior, so that the ceramic broke, the resulting powder from the impact area around the projectile fly out.

4: Cracks are created on the back of the ceramic, except for some radial cracks, the cracks are distributed into a cone, and damage will occur in the cone.

5: Cone ceramics are destroyed into pieces under complex stress conditions, and when the projectiles hit the ceramic surface, most of the kinetic energy is consumed in the area of the cone's bottom, the diameter of which depends on the mechanical properties and geometry of the projectile and ceramic materials. These are just the characteristics of the response of the ceramic armor at low speed/medium speed projectiles. That is, the response characteristics of the projectile speed of V50. When the projectile speed is higher than V50, the projectiles and ceramics will erode each other to create a mescall crushing zone, at which point both the armor and the projectile form in fluid form.
