NIJ Level III SiC Ceramic + HPPE Composite Tactical Ballistic Plate

I. Core Highlights: Four Key Advantages, Balancing Protection and Practicality

1. High-Level Protection Against Mainstream Rifle Ammunition

Compliant with NIJ Level III protection standards (when used in conjunction with a Level IIIA bulletproof vest), it can effectively stop 7.62×51mm M80 NATO (NATO full-power ammunition), 7.62×39mm AK47 MSC (AK47 standard ammunition), and 5.56×45mm M193/SS109 (common ammunition for M16/AR-15) at a distance of 15 meters. Each plate can withstand 3-6 consecutive hits, meeting the needs of high-risk missions such as SWAT counter-terrorism and military patrols.

2. Lightweight Design to Reduce Mobility Burden

Adopting a "monolithic SiC ceramic + HPPE (Ultra-High Molecular Weight Polyethylene)" composite structure, it controls weight while ensuring protection: each plate weighs only 1.85±0.05kg, 20% lighter than same-level aluminum oxide ceramic plates and 50% lighter than steel armor, with no obvious load fatigue during long-term wear.

3. Ergonomic Shape for Tactical Maneuvers

Features a multi-curve design that fits perfectly with the contour of the torso and chest, reducing pressure by 60%. The size of 254×305±3mm covers key vital areas such as the heart and lungs, and is equipped with an SE cut (Shooters Cut) for easy and quick insertion/removal into bulletproof vests. It does not hinder underarm movement, making it suitable for tactical actions like crawling and tactical leaps.

4. Strong Environmental Adaptability to Extend Service Life

The outer layer is wrapped in 600D Oxford fabric, treated with both waterproof and flame-retardant properties: it maintains stable performance in extreme environments from -30℃ to +50℃, does not seep water when used in rainy days, and does not burn when in contact with open flames. The fabric's wear resistance coefficient is 3 times that of ordinary canvas, capable of withstanding daily friction and field scratches to protect the internal ceramic and HPPE layers from damage.

III. Protection Principle: "Hard Resistance + Shock Absorption" Dual Mechanism to Block Bullet Threats

1. Step 1: SiC Ceramic Resists Bullet Impact

The monolithic SiC ceramic has a hardness of up to HV0.5 ≥ 2600 (second only to diamond). When a bullet hits, the ceramic surface instantly shatters the bullet's casing and core, transforming the bullet from a "sharp penetrator" into "flat debris." At the same time, the ceramic's rigid structure dissipates 80% of the impact force to prevent single-point penetration.

2. Step 2: HPPE Layer Absorbs Shock and Energy

The HPPE layer behind the ceramic layer acts as a "tough shock absorber." HPPE fibers made via the gel-spinning process are 15 times stronger than steel of the same weight. When bullet debris and remaining impact force are transmitted to the HPPE layer, the fibers undergo minor deformation, and the remaining kinetic energy is dissipated through this deformation process. Finally, the debris is completely stopped inside the plate without causing secondary damage.

IV. Application Scenarios: Targeted to Meet Needs, Covering Various High-Risk Missions

V. Usage Precautions: Proper Maintenance to Ensure Protection Effectiveness

1. Storage: Store in a dry, dark environment. Avoid long-term exposure to humid conditions (relative humidity ＞ 80%) or direct UV exposure to prevent aging of the HPPE layer and moisture damage to the ceramic layer.

2. Service Life: Under normal use, replacement is recommended every 5-8 years. If ceramic cracking, outer fabric damage, or hardening of the HPPE layer occurs, stop using immediately.

Taboos: Do not drop, smash, or roll over the plate to avoid hidden cracks in the ceramic layer; do not contact with strong acid or alkali solutions to prevent corrosion of the fabric and internal materials.

1. What is Level 7 Body Armor?

UL 752 Level 7 ballistic barriers are the standard definition for this type of ballistic protection product, whose core purpose is to withstand multiple shots from military assault rifles (such as the M-16 model). The muzzle energy of bullets fired by such rifles typically ranges from 1158 to 1402 foot-pounds (converted to 1570 to 1901 joules). From the perspective of product specifications, the standard thickness of Level 7 ballistic-related components is 1 to 1 and 1/8 inches, and the standard weight per square foot is approximately 11.7 pounds.

2. Can Ballistic Plates Resist Knife Stabs?

Steel ballistic plates have the ability to resist knife attacks, but they are usually more suitable for scenarios where "ballistic threats are the primary risk". Compared with ballistic plates made of other materials, steel ballistic plates are relatively heavy, so they are not the first choice for scenarios that only require protection against knife stabs.

3. Can Civilians Purchase Bulletproof Vests?

Bulletproof vests are classified as safety protection products. In the United States, as long as one is a law-abiding citizen, they have the right to purchase bulletproof vests in all 50 states, whether for personal protection or work needs. Protecting the safety of oneself and one's family is a legal right.

4. Is It Illegal to Wear a Stab Proof Vest?

Generally, it is permitted to carry or wear a stab-proof vest in public places, unless there are explicit restrictive regulations in some specific places or scenarios. However, it should be noted that wearing a stab-proof vest may arouse doubts or unnecessary attention from others, so it is advisable to pay attention to the feelings of people around.

5. Can Bulletproof Vests Resist Stabs?

No. When sharp weapons such as knives (edged weapons) attack, they will cut the protective fibers in the bulletproof vest, causing the vest to lose its protective function; while pointed weapons such as nails (spiked weapons) can pass through the small gaps in the protective fabric and cannot be blocked either. Therefore, bulletproof vests are only designed for bullets and do not have the function of resisting stabs from sharp or pointed weapons.
