Product Description

Product Description

Structure and Performance

Silicon carbide (SiC) mainly has two crystal structures, namely cubic β-SiC and hexagonal α-SiC. It is a compound with strong covalent bonds, and the ionic type of its Si--C bond is only about 12%. Therefore, compared with other ceramics such as alumina and boron carbide, it has better mechanical properties, oxidation resistance, higher wear resistance and lower friction coefficient. In addition, its excellent properties such as good thermal stability, high high temperature strength, small thermal expansion coefficient, high thermal conductivity, good thermal shock resistance and chemical corrosion resistance have been favored by military experts from various countries and are widely used.

Bulletproof principle
The basic principle of armor protection is to consume the energy of the bullet, slow down the bullet and make it harmless. Most traditional engineering materials, such as metal materials, absorb energy through plastic deformation of the structure, while ceramic materials absorb energy through micro-crushing process.
The energy absorption process of silicon carbide bulletproof ceramics can be roughly divided into three stages:
(1) Initial impact stage: The bullet hits the ceramic surface, making the bullet blunt, and absorbs energy in the process of crushing the ceramic surface into small and hard fragments;
(2) Erosion stage: The blunted bullet continues to erode the fragment area, forming a continuous layer of ceramic fragments;
(3) Deformation, crack and fracture stage: Finally, tensile stress is generated in the ceramic to cause the ceramic to break, and then the back plate is deformed, and the remaining energy is all absorbed by the deformation of the back plate material. In the process of the bullet hitting the ceramic, both the bullet and the ceramic are damaged.

Ballistic Material for the Plates:

i)  Alumina(AL2O3) Ceramic Tiles & UHMWPE Backing (III-IV)

ii) Silicon Carbide( SIC) Ceramic Tiles & UHMWPE Backing (III-IV)

iii) 100% Pure UHMWPE( III / III+/ III++)

Bulletproof Plate Cutting:

i)  SAPI cut is the shape of SAPI boards that fill the streets. (e.g. SAPI/ESAPI)

ii) Special tailoring refers to more aggressive corner cuts than SAPI, facilitating arm movements and shoulder support.
There are so-called SHOOTERS cut and SWIMMER cut.

iii) Traditional cutting includes the simplest square board, the smallest reinforcement, and small corners similar to RBA. (such as FULL SIZE)


Construction:

i)  in conjuction with (ICW.) IIIA or lower threat level soft armor panel;        
  
ii) Stand Alone(SA.),which means it can protect against the III/IV rating  threat without any soft armor ballistic panels / inserts.
