Material type:
Boron Carbide, also known as black diamond (hard black shiny crystal), has a molecular formula of B4C, a molar hardness of 9.3, and a relative density of 2.508 to 2.512. The melting point is 2350°C. Boiling point 3500℃, strong covalent bond compound (covalent bond as high as 93.9%), is one of the three hardest materials known (the other two are diamond, cubic boron nitride), and it is a modern lightweight bulletproof material application The first choice in the field of ballistic ceramic materials.
Boron carbide has a high melting point and exceptional hardness (in several commonly used armor ceramics, the density is the lowest, the hardness is the highest, and the elastic modulus is high, making it a good choice for military armor and space materials. Widely used in occasions with extremely strict quality requirements).
Boron carbide is a ceramic material with high hardness and low density. The boron carbide bulletproof ceramic plate is made by hot pressing and sintering process. The product has obvious advantages and characteristics such as good elasticity resistance and light weight.
Among the various bulletproof ceramics currently available, boron carbide (B4C) ceramics have the lightest specific gravity, the highest hardness and elastic modulus. It is the hardest material except diamond and cubic boron nitride, and is modern lightweight Ballistic-resistant ceramic materials are the first choice in the application of ballistic materials, with obvious weight reduction effects, but due to the extremely high processing technology requirements, the cost is also high.
Bulletproof mechanism:
The high hardness of the boron carbide ceramic material enables it to passivate and break the warhead in time, and absorb the energy of the high-speed warhead through its own crushing process.
With the development of lightweight and high-efficiency armor systems, the superiority of boron carbide bulletproof ceramics has become more prominent.
Under the action of the large impact force of the warhead, the boron carbide ceramic material mainly absorbs energy through the micro-crushing process. The main process is roughly divided into three stages: the initial impact stage, the erosion stage and the deformation fracture stage. The boron carbide ceramic surface layer can passivate the warhead, and the surface is crushed into small and hard particles. When the dull projectile continues to deepen, the boron carbide ceramic forms a fragment layer. The tensile stress inside the material causes the ceramic to crack, and the remaining energy is caused by the back The board absorbs. The ability of ceramics to absorb energy is related to the hardness and elastic modulus of ceramics. Generally, ballistic quality factors are used to comprehensively measure the anti-elastic performance of ceramics: The greater the elastic modulus and hardness of ceramics, the lower the density, the stronger the ceramic's ability to absorb kinetic energy. , That is, the better the ballistic performance.
Structure process:
The bullet-proof insert includes a front surface (boron carbide ceramic), a back plate (ultra-high molecular weight polyethylene fiber laminate), and an interface (adhesive composite crack arrest layer). The structure conforms to the energy absorption mechanism of ceramic armor. Among them, the boron carbide ceramic adopts the whole board process to eliminate the weak points of bulletproof caused by the small ceramic splicing gaps in the traditional process, improve the overall ballistic performance, reduce the depth of the depression, and eliminate the potential breakdown risk caused by laying small pieces of ceramic based on experience to the greatest extent.
Single-curved/multi-curved design fits ergonomics, and the four corners are smooth. The two gradually shrinking upper corners are more suitable for the human body shape, which facilitates the removal and installation of the plug-in board, and ensures greater movement during tactical actions. Amplitude.
When a soldier or police officer encounters a threat of high-powered bullets, they can be quickly inserted into the front side of the soft body armor, which can strengthen the bulletproof protection of the vital organs of the wearer's torso.
