It can be divided into two groups,
Textile (woven) armor based on aramid fibers
Today, the body has an armor fiber. The characteristics of ballistic fabrics are significantly different from those of the world. It has been found in its chemical properties.
What is aramid fiber? Other colors are very rarely used. Aramid yarns are made from yarns. Aramid fiber has very high mechanical strength.
Aramid has been fully realized. For example, the “protection / weight” ratio. This indicator is made from ultrahigh-molecular polyethylene (UHMWPE). At the same time, the physical density of UHMWPE is 1.5 times less.
Marks of ballistic fabrics:
- Kevlar ® (Dupont, USA)
- Twaron ® (Teijin Aramid, Netherlands)
- SVM, RUSAR® (Russia)
- Heracron® (Colon, Korea)
Metal armor based on steel (titanium) and aluminum alloys
The armor plates were made of steel and were widely used during the First and Second World Wars. Light alloys began to be applied later. For example, during the war in Afghanistan, it is widespread. If you want to make it possible, it’s possible to reduce the weight of the product.
Aluminum armor. Aluminum is superior to steel armor, providing protection against armor-piercing bullets of 12.7 or 14.5 mm caliber. In addition, it has a unique material.
Titanium alloys. The main advantage of titanium alloys is a combination of corrosion resistance and high mechanical properties. It is the alloy of the chromium, the aluminum, the molybdenum and other elements.
Ceramic armor based on composite ceramic elements
Since the beginning of the 80s, it has been used in the “protection / weight ratio”. However, the use of ceramics is possible only in combination with composites of ballistic fibers. It is necessary to solve the problem of low survivability of such armored panels. It is also not always possible to effectively realize all the properties of ceramics, since such an armor requires careful handling.
In the 1990s, the armored panels were outlined in the 1990s. Until then, ceramic armored panels are strongly lost on this indicator. Thanks to this granite-4 family.
The bodywork of the solid ceramic monoplates. This is a chance to get a chance on a soldier during a fight. Secondly, such products are much more technological, i.e. It is less time consuming, and it is not.
- Aluminum oxide (corundum);
- Boron carbide;
- Silicon carbide.
Composite armor based on high modulus polyethylene (laminated plastic)
To date, the most advanced type of armor from 1 to 3 class (in terms of weight) are ultra high modulus polyethylene.
UHMWPE fibers have high strength, catching up with aramid fibers. They do not need to lose their protective properties. However, the body armor is not suitable. There is a high risk of fire or hot objects. Moreover, bulletproof vest is often used as bedding. It remains a polyethylene and doesn’t exceed 90 degrees Celsius. However, the UHMWPE is great for making police vests.
It is worth noting that it is not possible to ensure that it is hard. It can be protected from pistol bullets and splinters. To protect against bullets of long-barreled weapons, you must use armor panels. It is a small area of energy. Not defined. It is a composite base of armored plates.
Aramid for ballistic products are:
- Daynim® (DSM, the Netherlands)
- Spectra® (USA)
Combined (multilayer) armor
The body will be used. It was possible to significantly improve the protective properties of armor clothing. It has been widely used today throughout the world.
Body armor However, it’s not a decisive role. There is a tendency to increase in weight and weight. Kevlar gel for use with hydrophobized, which has been reduced to five times. This armor can significantly reduce the size of the armor, while maintaining the same class of protection.
