Specification of R400 Single Curved Boron Carbide B4c Ceramic Armour Sheet Nij Level IV
R400 boron carbide ceramic armor plates stop serious rifle bullets. They meet the demanding NIJ Level IV standard. This means they defeat common armor-piercing rifle threats. The R400 uses single curved plates. This shape fits the body better than flat plates. It provides more comfort and better coverage.
Boron carbide is the key material. It’s called B4C. This ceramic is incredibly hard. Hardness matters against bullets. The hard surface breaks up the bullet on impact. This absorbs the energy fast. Boron carbide is also very light. It weighs much less than steel armor. Expect plates roughly 70% lighter than steel plates offering the same protection. This light weight reduces fatigue. Soldiers and officers can move better.
The R400 plate is designed for multiple hits. It can stop several shots. This multi-hit capability is vital. Real threats often involve multiple rounds. The ceramic tile is bonded to a tough backing material. This backing catches fragments. It holds the ceramic together after impact. This backing is crucial for consistent performance. It prevents pieces from breaking off. The front face is a dense, black, glassy ceramic surface. This surface is the first line of defense.
These plates are made for serious use. They are for military and law enforcement personnel. They fit into plate carriers designed for hard armor. The R400 provides reliable protection against high-powered rifles. It does this without excessive weight. The single curve improves wearability. The boron carbide core ensures top-level ballistic resistance. This armor keeps people safe from rifle fire. It stops armor-piercing bullets effectively.
Applications of R400 Single Curved Boron Carbide B4c Ceramic Armour Sheet Nij Level IV
The R400 Single Curved Boron Carbide (B4C) Ceramic Armour Sheet provides high-level ballistic protection. It meets the demanding NIJ Level IV standard. This means it reliably stops powerful rifle threats like the 7.62x63mm M2 AP (.30-06 AP) bullet. Boron carbide is one of the hardest materials known. It offers exceptional stopping power. It is also very lightweight compared to steel armor. This weight reduction is critical for user mobility and endurance.
The single curve design is important. It contours better to the human body than flat plates. This improves wearer comfort significantly. Better fit also enhances protection coverage. The curved shape helps deflect impacts slightly. This aids the armor’s ability to break up bullets. The ceramic face shatters the projectile’s core. The layered backing material catches the fragments. This combination stops the threat.
These armor sheets are used in many critical applications. Soldiers wear them in tactical plate carriers for chest and back protection. Law enforcement officers use them during high-risk operations. They are integrated into military vehicle doors and hulls for added crew safety. Aircraft, especially helicopters, benefit from these plates shielding pilots and critical components. They are also used in VIP vehicle armor packages. The lightweight nature makes them suitable for extended wear or adding protection without excessive weight.
The R400 plates are custom-made to fit specific armor systems. Different sizes and precise curvature are available. This ensures optimal performance within the vest or vehicle panel. They undergo strict quality control and ballistic testing. This guarantees they meet the NIJ Level IV requirements every time. You get proven protection against serious rifle rounds. The combination of boron carbide ceramic and the single curve design delivers life-saving defense. It balances protection, weight, and wearability effectively for demanding situations.

5 FAQs of R400 Single Curved Boron Carbide B4c Ceramic Armour Sheet Nij Level IV
People ask many questions about the R400 Single Curved Boron Carbide B4C Ceramic Armour Sheet. Here are five common ones:
What threats does the R400 stop? It defeats NIJ Level IV threats. This means it stops armor-piercing .30 caliber rifle rounds. Think M2 AP or similar hard-hitting bullets. It meets strict ballistic standards.
Why use Boron Carbide? Boron Carbide (B4C) is extremely hard. Hardness matters for stopping bullets. It shatters incoming projectiles on impact. This material is lighter than steel. It offers high protection without excessive weight.
What’s the benefit of the single curve shape? The curve fits the body better. A flat plate feels awkward against your torso. The curve improves comfort during wear. It helps the plate sit correctly in your carrier. Movement is less restricted.
How heavy is the R400 plate? Weight is a major concern. Boron Carbide helps keep it low. The R400 provides Level IV protection efficiently. You get critical defense without carrying unnecessary pounds. Check exact weights for your size.
Can I use this plate with my existing gear? Yes, usually. The R400 follows standard sizing like SAPI or ESAPI. It fits most plate carriers designed for these cut shapes. Confirm your carrier’s specific cut requirements. Compatibility is generally good.
