Material characteristics:
Silicon Carbide (Silicon Carbide), also known as emery, is made up of Si-C tetrahedrons with a Mohs notch hardness of 9.2 and a relative density of 3.08 to 3.12.
The covalent bond of silicon carbide is extremely strong, and it still has high-strength bonding at high temperature. This structural feature gives silicon carbide ceramics excellent strength, high hardness, wear resistance, corrosion resistance, high thermal conductivity, and good heat resistance. Vibration and other properties, at the same time, silicon carbide ceramics are moderately priced and cost-effective. They are considered to be one of the most promising high-performance armor protection materials.
We have broken through the preparation technology of the large-size integral arc-shaped bullet-proof board, so that it has the ability to resist multiple strikes, optimize the structural design, improve the ballistic performance, and can avoid or significantly reduce the non-penetrating damage caused by the bombardment of the human body. Through the design of the specific gravity of the PE board and the silicon carbide board in the bulletproof insert, under the premise of weight reduction, the various bulletproof performance indicators meet the military standard requirements, and the material cost of the bulletproof insert is maximized.
Bulletproof mechanism:
Under the action of the large impact force of the warhead, the ceramic material mainly absorbs energy through the micro-fragmentation process. The main process is roughly divided into three stages: the initial impact stage, the erosion stage and the deformation fracture stage. The armored ceramic surface layer can passivate the warhead, and the surface will be crushed into small and hard particles. When the blunt projectile continues to deepen, the armored ceramic will form a fragment layer. The tensile stress inside the material will cause the ceramic to break, and the remaining energy will be absorbed by the back plate. . 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 (silicon 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 silicon 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 ceramic pieces 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.
