Class 4 armor plates (NVMPE +Al₂O₃) М

The BRONYX set includes two protective plates rated Class 4 under DSTU 8782:2018. Each plate measures 25 × 30 cm, is 25 mm thick, and weighs 2.9 kg. The pair weighs 5.8 kg in total. The protective elements are made from silicon carbide (SiC) ceramic, ultra-high-molecular-weight polyethylene, and cushioning layers. The Shooter’s Cut shape, with angled upper corners, leaves room for shoulder movement. The two-curve design helps the plates sit closer to the chest.

Features of the BRONYX M Plate Pair

The set is designed to fit the front and rear compartments of a plate carrier. The 25 × 30 cm format is common for size M models. The recommended chest circumference is up to 110 cm, with an approximate tolerance of 5 cm.

Key features of the set:

• two protective plates in one set;
• Class 4 protection under DSTU 8782:2018;
• size M, measuring 25 × 30 cm;
• silicon carbide (SiC) ceramic layer;
• UHMWPE backing;
• cushioning layers made of foamed polyethylene;
• Shooter’s Cut shape;
• two-curve design;
• outer Oxford fabric cover;
• manufactured in Ukraine.

Matching plate specifications help distribute weight evenly between the front and rear of the gear. After installation, adjust the shoulder straps and cummerbund to account for the full weight of the set. The plates should stay at the intended height while walking, bending, and squatting.

Class 4 Protection under DSTU 8782:2018

BRONYX meets Class 4 of the Ukrainian standard DSTU 8782:2018. According to the supplied specifications, the plates are designed to protect against 5.45 × 39 mm PP 7N10 and 7.62 × 54 mm LPS 57-N-323s projectiles.

Specified test projectiles and velocities:

• 45 × 39 mm PP, index 7N10;
• 45 × 39 mm projectile velocity: 910 ± 15 m/s;
• 62 × 54 mm LPS, index 57-N-323s;
• 62 × 54 mm projectile velocity: 850 ± 15 m/s.

These figures apply to the test conditions defined by the standard. Before use, check the protection rating, serial markings, and accompanying documents for the plates received. Other projectiles of the same caliber may differ in design, core material, and velocity.

Specified Backface Deformation

Backface deformation describes the change in the rear surface after a projectile is stopped. This measurement helps assess how residual energy is transferred to the cushioning layer and the area of the body behind the protective element.

Maximum values stated in the product description:

• 0 mm for 5.45 × 39 mm PP 7N10;
• 24 mm for 7.62 × 54 mm LPS 57-N-323s.

Results should be considered together with the test report and the method used. The impact location, projectile velocity, and condition of the specific plate may affect deformation. After an impact, the protective element must be taken out of service.

Multilayer Protective Plate Construction

The BRONYX protective system consists of several materials, each with a specific function. The ceramic receives the initial impact from the incoming projectile. The polyethylene backing retains fragments and distributes the remaining load.

The construction includes:

1. A front layer of foamed polyethylene.
2. Silicon carbide (SiC) ceramic.
3. UHMWPE backing.
4. A rear layer of foamed polyethylene.
5. An outer Oxford fabric cover.

Foamed polyethylene protects the main composite from some mechanical loads and provides cushioning. Oxford fabric protects the internal materials from abrasion and dirt. Damage to the outer cover calls for an inspection of the protective element.

How Do SiC and UHMWPE Work?

Silicon carbide is very hard, allowing the ceramic layer to act on the penetrating part of a projectile on impact. At the impact point, SiC fractures, absorbing some of the energy and damaging the core.

The UHMWPE backing sits behind the ceramic. It retains projectile and ceramic fragments, helping preserve the integrity of the plate’s rear surface. The multilayer polyethylene structure also distributes the load over a wider area.

Ceramic protective elements should be guarded against hard impacts and drops. An internal crack can form without visible external damage. After significant mechanical impact, the plates should be professionally inspected.

Size M for 25 × 30 cm Plate Carriers

Each protective plate measures 25 × 30 cm. Size M is recommended for users with a chest circumference of up to 110 cm, with an approximate tolerance of ±5 cm. The user’s measurements should be compared with the coverage area and the position of the plate on the torso.

Before ordering, check:

• the internal width of the carrier compartment;
• the available pocket height;
• compatibility with the 250 × 300 mm format;
• the permitted thickness of 25 mm;
• the shape of the compartment’s upper corners;
• whether the lower flap can close fully;
• room for an additional cushioning insert.

Size M markings can correspond to different internal dimensions across carrier manufacturers. The pocket’s exact measurements must accommodate both the protective plate and the cushioning insert. Minimize excess space inside the compartment to prevent the plate from shifting during movement.

Shooter’s Cut Shape

Shooter’s Cut has angled upper corners that free up part of the shoulder area. This geometry makes it easier to move the arms, bring equipment forward, and change torso position. The shape is also compatible with many modern plate carriers.

After installation, check mobility while wearing the full kit. Pouches on the front panel may limit range of motion. Adjust their positions after a few training sessions.

Two-Curve Design

The two-curve design helps the protective plate follow the shape of the chest. This brings the edges closer to the body and spreads contact pressure over a larger area.

Use the manufacturer’s markings to identify the front and rear surfaces. Install the plates with the curve facing the body, in the intended position. Incorrect placement can affect fit and may go against the design of the protective element.

Weight of the Plate Pair

Each plate weighs 2.9 kg. The pair weighs 5.8 kg in total. When calculating the load, also account for the weight of the plate carrier, pouches, side protection, and other equipment.

Key set specifications:

• quantity: 2 pcs.;
• weight of one plate: 2.9 kg;
• total weight of the pair: 5.8 kg;
• size: M;
• dimensions of one plate: 250 × 300 mm;
• thickness: 25 mm;
• recommended chest circumference: up to 110 cm, ±5 cm;
• curve: two-curve;
• shape: Shooter’s Cut.

Distribute the full equipment load between the shoulder straps and cummerbund. Padded shoulder straps can help reduce localized pressure. Make final adjustments after installing both plates and the main pouches.

Installing the Plates in a Plate Carrier

One plate goes in the front compartment and the other in the rear. Before installation, inspect the covers, check the markings, and identify the top edge of each protective element.

Installation steps:

1. Check the Oxford outer layer for damage.
2. Identify the front and rear surfaces of the plates.
3. Insert the first element into the front compartment.
4. Place the second plate in the rear pocket.
5. Add cushioning inserts if needed.
6. Close the lower flaps fully.
7. Adjust the shoulder straps and cummerbund.
8. Check the fit while moving.

The upper edges of the front and rear plates should sit at the appropriate anatomical height. The protective elements should remain stable while bending and squatting. Check their position again after installing the pouches.

Care and Storage

Transport composite plates in a way that reduces the risk of drops and impacts. A plate carrier, protective bag, or original packaging can be used. Temperature and humidity should meet the manufacturer’s recommendations.

During inspection, check:

• the condition of the Oxford fabric;
• the edges and upper cuts;
• for any delamination;
• that the two-curve shape is intact;
• that the markings are legible;
• the date of manufacture;
• the specified service life.

Do not place heavy objects on the plates during storage. Stop using them after a drop, hard impact, or strike. Their continued serviceability should be determined through a specialized inspection.
