Ballistic Testing Standards And Protection Levels
Before understanding bulletproof materials, you should first understand some knowledge about ballistic testing standards and protection levels, which will help you choose the most suitable bulletproof material!
UL Standards
UL (Underwriters Laboratories) has eight grades for bulletproof materials:
o UL 1-3: Mainly for pistol bullets, such as 9mm and .357 Magnum.
o UL 4-6: For rifle ammunition, such as .30-06 and 7.62mm.
o UL 7-8: Can defend against high-powered ammunition and multiple impacts.
NIJ Standards
NIJ (National Institute of Justice) has four main grades from I to IV:
o Grade I: Can defend against small-caliber bullets such as .22LR.
o Grade II and Grade IIIA: Suitable for light bulletproof equipment for daily use, such as bulletproof vests.
o Grade III and Grade IV: Higher-grade materials can defend against rifle bullets and high-penetration ammunition, suitable for military and special protection needs.
What Materials Are Bulletproof?
With the improvement of people’s awareness of protection, various bulletproof materials have emerged, covering lightweight and simple protective equipment and high-strength building materials. It should be clear that no material can completely protect against bullets. Currently known bulletproof products will be penetrated by the critical value of impact. However, these bulletproof materials can still play a very important role and can protect people from bullets to the greatest extent.
We will fully analyze these common bulletproof materials for you to help you understand them in depth.
Steel
Steel is the most well-known traditional building bulletproof material. The advantages of this type of material are high strength and good durability. Its strong mechanical strength can resist a variety of mechanical attacks.
The bulletproof performance of steel is mainly determined by thickness and special surface treatment. The most common bulletproof steels on the market are wear-resistant (AR) steel, high-carbon alloy steel, etc. These steels can effectively resist the powerful impact of bullets and are the best type of steel for bulletproof effect.
Although steel has unparalleled bulletproof performance, its heavy weight and easy rust and corrosion are headaches, and additional protective treatment is required. In addition, steel is not beautiful, and it is obviously not an ideal material for buildings that require design and beauty.
Ceramics
Ceramic materials have become another common bulletproof material because of their extremely high hardness. Compared with steel, ceramics are harder and can more effectively disperse the energy of bullets, prevent bullet penetration, and are not easily corroded. Ceramics are about 37% lighter than steel, which makes them more convenient to install. At the same time, ceramics are cheaper than PE (polyethylene), making them a very cost-effective material.
Common bulletproof ceramics include boron carbide, silicon nitride and silicon carbide, which are currently widely used in the military and security fields.
Of course, ceramic materials have more than just advantages. Bulletproof ceramics are brittle and prone to cracks. After multiple impacts, they are likely to break and lose their original protective capabilities. Therefore, in order to improve the protective capabilities of ceramics, they are usually used in combination with other materials (Kevlar and steel).
Fiber materials
Kevlar and Ultra-High-Molecular-Weight Polyethylene (UHMWPE) are two common fiber-based bulletproof materials, which are characterized by lightness and high strength.
Kevlar is often used to make protective equipment such as bulletproof vests and helmets, which can effectively absorb the kinetic energy of bullets and reduce the damage caused by impact to the human body.
Polyethylene, referred to as PE, is a lightweight material with excellent impact resistance. Compared with Kevlar, it has better bullet resistance and can be used to make bulletproof shields, car windows and other building protection.
The lightness and portability of fiber materials are the main advantages, but their protective ability is relatively weak in the face of high-powered bullets.
Glass materials
Bulletproof glass is a very important transparent protective material, which is widely used in banks, airports and other places. Bulletproof glass is composed of multiple layers of glass and plastic (such as polycarbonate) alternating layers, which makes bulletproof glass transparent and beautiful while also having superior bulletproof capabilities.
The bulletproof grade of bulletproof glass is determined by thickness and number of layers. High-grade bulletproof glass can resist high-powered firearm attacks. However, bulletproof glass also has the problems of heavy weight and high thickness, and the cost of installation and maintenance is high.
Polycarbonate
Polycarbonate is a transparent, high-strength plastic that is often used to make bulletproof windows and bulletproof panels. Polycarbonate has good transparency and stronger impact resistance than ordinary glass, and is suitable for places that require protection and transparency.
Polycarbonate also has disadvantages. If it is exposed to ultraviolet rays for a long time, its surface will gradually turn yellow, seriously affecting its appearance and transparency.
Graphene - Future Trend
In the research and development of bulletproof materials, graphene has received attention. Some people wonder, is graphene bulletproof? Yes, as a new material, graphene is known as one of the “hardest materials in the world”. It has a tensile strength 200 times stronger than steel and can be very thin and light. It is an ideal bulletproof material and can be used as graphene bulletproof armor and graphene bulletproof vests.
In theory, graphene is expected to become the core material of the next generation of bulletproof technology, but at the current stage, due to the high cost and technology, graphene is still in the research stage. We believe that with the development of science and technology, graphene will soon become a new star in the new bulletproof material.
Application And Comparison Of Bulletproof Materials
Different bulletproof panels have their own advantages and disadvantages, and each has its own areas of expertise. In this section, we will compare different bulletproof materials to give you a more intuitive understanding of them, so as to help you make more informed decisions and solutions based on your actual needs.

Steel vs Ceramics: Traditional Protection vs High Hardness Materials
Steel and ceramics are both very common bulletproof materials now, but their characteristics and applicable scenarios are different.
Steel is hard and tough and is suitable for high-threat environments, such as some military protective vehicles, police car protection and heavy-duty protective walls. The disadvantage of steel is obvious, that is, it is too heavy, which makes the installation process too difficult, and steel is easy to rust. Anti-rust treatment is also a big expense, and the effect of long-term use is not good.
Ceramics have extremely high hardness and can quickly disperse the energy of bullets to achieve superior bulletproof effects. Ceramic materials are also widely used in military defense, such as combat vehicles, bulletproof vests, etc. The bulletproof effect of ceramics is remarkable, and if a multi-layer protective structure is used, greater advantages can be exerted. However, the more obvious flaw is that it is too brittle, and the protective effect will gradually be lost after cracks occur. Therefore, it is usually used in combination with other materials to improve the overall performance.
How to choose ceramic and steel? If your application scenario does not have high requirements on weight and only protects some powerful bullets, then we think steel is your ideal choice; if you have higher requirements for protective performance and take into account the high hardness of ceramics and the need for multiple tests For protection, ceramics will be a more suitable choice for you!
Fiber materials vs. glass materials: lightweight protection vs. transparent protection
Kevlar and polyethylene are both relatively lightweight bulletproof materials, which have the advantages of carrying and installation. Glass materials dominate transparent protection.
Fiber materials: Kevlar has high strength and light weight, which can effectively reduce the impact damage caused by bullets to the human body. It is especially suitable for occasions that require flexible movement, such as bulletproof equipment for police and criminal police, but Kevlar’s protective ability is limited and is not enough to protect against high-powered bullets. Polyethylene is lighter than Kevlar and has stronger bullet resistance than Kevlar. For high-speed flying bullets, its protective ability is not inferior to traditional steel. In some high-risk areas, polyethylene is used in shields and bulletproof car windows, and is a very effective bulletproof material. However, it also has a very fatal disadvantage. Polyethylene is more sensitive to high temperature environments, so it is not suitable for use in those extreme climates or high temperatures.
Glass materials: Bulletproof glass is a combination of multiple layers of laminated glass and polymer film. This protective material can effectively absorb impact energy and maintain good light transmittance. Therefore, bulletproof glass is suitable for places that require visual transparency and high protection performance, such as bank counters, airport security windows, bus windows, etc. Polycarbonate is a transparent plastic. Compared with bulletproof glass, it is lighter and easier to install, but its bulletproof performance is inferior to bulletproof glass, and it is more used in some medium protection scenarios.
How to choose fiber materials and glass materials? If you need personal protection, or use it for light and flexible protection, then fiber materials are your first choice. Of course, glass materials are not suitable for personal protection. They are more used in occasions with a tendency to be transparent and require a stronger level of protection.

Glass-like materials vs. polycarbonate: different choices for transparent protection
We mentioned the characteristics of the two types of transparent protection earlier. From a cost perspective, bulletproof glass is more expensive and heavier, and installation also requires professional technical support. Polycarbonate is lighter and has higher protection performance, especially when facing high-speed bullets, but its transparency is average compared to glass, which affects the appearance.
How to choose glass-like materials and polycarbonate? If your application scenario requires high visual clarity and your budget is sufficient, then we recommend that you use bulletproof glass; if you value impact resistance more, then polycarbonate provides you with a lighter and more cost-effective option.
Characteristics Of Bulletproof Ceramics
Ceramic materials have been applied to all aspects of our lives and occupy an indispensable position. My police friend praised bulletproof ceramics. He shared his story with us. Because of the superior bulletproof performance of bulletproof ceramics, he survived the terrible bullet by chance… Yes, not only as bulletproof vests, ceramic materials have been widely used in military, police, security equipment and other fields. Bulletproof ceramics have gradually become an important part of modern protection systems.
Next, we will take you to understand the various bulletproof ceramics.
Excellent hardness and impact resistance
The core performance of bulletproof ceramics is hardness. Many ceramic materials have a hardness comparable to that of diamond. Among the many ceramic materials, compounds such as silicon carbide (SiC), boron nitride (BN) or silicon nitride (Si3N4) are commonly used for bulletproofing. These materials have excellent impact resistance, far exceeding that of steel.
In the face of high-speed bullet impacts, ceramics can be very effective and can disperse the energy of bullets to the greatest extent. After being hit by bullets at high speeds for many times, the surface of the ceramics will crack or break. This fragmentation phenomenon absorbs most of the energy. Even if the ceramics break, they can still effectively block bullets due to their hard structure and hardness. Therefore, some people often regard ceramics as the “first line of defense”. Hard ceramics can destroy the integrity of bullets, slow down the speed of bullets in flight, and protect humans from harm.
Lightweight and high performance
Ceramics are much lighter than traditional steel concrete, which makes them the first choice for military bulletproof materials. Even for heavy protective facilities that need to withstand a lot of impact, ceramics can provide superior impact resistance.
If lighter ceramics are combined with fiber materials such as Kevlar, they can be made into bulletproof vests, which not only ensures lightweight efficiency but also improves protective performance.
With reasonable matching materials, bulletproof ceramics can not only reduce the burden on equipment, but also achieve optimal energy absorption in multi-layer protection. This is why bulletproof ceramics are loved by so many people.
Multilayer structure and enhanced performance
I mentioned in the previous section that ceramics can be combined with other materials to improve performance. Yes, the protective performance of bulletproof ceramics is enhanced by multilayer design. The brittleness of a single layer of ceramics loses its protective ability after being subjected to multi-layer impact. Therefore, if ceramics are combined with polyethylene, steel plates or Kevlar, a multilayer composite structure is formed. Using ceramics as the first layer or core layer can play a key role in absorbing the bullet by relying on hardness and brittleness, while the second layer can use more flexible materials to absorb the remaining impact energy.
This not only enhances the overall protective ability, but also extends the service life of bulletproof equipment.
High temperature resistance and durability
Ceramic materials have excellent high temperature resistance, which allows them to maintain excellent protection in extreme high temperatures, especially the high temperatures generated by bullet impact. Many bulletproof ceramic materials are more stable than metal materials in high temperatures, which is extremely important for battlefields in harsh environments. In the face of explosions or fires, ceramic materials can provide longer protection and stability.
At the same time, corrosion resistance is also a very prominent feature of ceramic materials. This property prevents bulletproof ceramics from being easily affected by weather, humidity, and salt spray, and has a longer service life, reducing the frequency of maintenance and replacement.
Cost
Although ceramics have outstanding performance, they are expensive, especially high-end ceramic materials such as silicon carbide and silicon nitride. The processing technology of ceramics requires precise instruments and high-temperature firing. At the same time, ceramic materials are not easy to install. The high brittleness means that if they are not installed properly, large-scale damage may occur after impact.
But the good news is that with the advancement of technology and the improvement of production technology, the production cost of ceramic materials has gradually decreased, and more and more fields can use ceramics as the preferred option for protection.
Conclusion
As the global security needs grow, bulletproof materials play an increasingly important role in protecting individuals and facilities from impact damage. From traditional steel to modern composite materials, bulletproof technology is constantly improving to meet increasingly complex security challenges.
