What are the Most Used Famous Materials for Bulletproof Equipment?

 

    Bulletproof vests and bulletproof inserts have become standard equipment for law enforcement agencies and the military when carrying out missions. So what are the materials that can be used to make bulletproof equipment?

 

    1. Soft bulletproof materials: Soft bulletproof materials are usually composed of multiple layers of polymer materials and ceramic sheets. They have good impact resistance and bulletproof performance, but their protection range is limited.

 

    2. Hard bulletproof materials: Hard bulletproof materials are mainly made of hard materials such as ceramics and boron carbide. These materials have high hardness and can withstand the impact of high-speed bullets.

 

    3. Enhanced bulletproof materials: Enhanced bulletproof materials are mainly made of high-performance fibers such as glass fiber and carbon fiber. They have high strength and stiffness, which can effectively absorb the energy of bullets and improve their bulletproof ability.

    Since the 21st century, bulletproof ceramics have developed rapidly with a variety of types, including alumina, silicon carbide, boron carbide, silicon nitride, titanium boride, etc. Among them, alumina ceramics (Al2O3), silicon carbide ceramics (SiC), and boron carbide ceramics (B4C) are the most widely used.

 

    Aluminum oxide is also known as alumina, which is a ceramic material. Ceramic plates are used in body armor because they are very hard and can shatter or fracture upon impact, disrupting and absorbing the energy from the projectile. This helps to prevent the projectile from penetrating the armor and causing injury.

 

    Silicon carbide materials have excellent mechanical properties, oxidation resistance, high wear resistance, and low friction coefficient. In addition, they have good thermal stability, high temperature strength, small coefficient of thermal expansion, high thermal conductivity, and good resistance to thermal shock and chemical corrosion, which have been favored by military experts from various countries and widely used.

 

 

    Boron carbide is currently known as a superhard material with a hardness second only to diamond and cubic boron nitride. It has a high elastic modulus, low coefficient of thermal expansion, and high thermal conductivity. The density of B4C is the lowest among several commonly used armor ceramics, and its high elastic modulus makes it a good choice for materials in military armor and space fields.
