Domestic enterprises presented new types of ceramic armor

17
In our country, the development and production of promising materials for use as part of the design of armored vehicles or personal protective equipment continues. At the recent Open Innovations Forum, Russian companies NEVZ-Ceramics and Virial presented their new developments in the field of ceramic armor. New materials and technologies allow to protect the fighter from various rifle weapons.


During the recent exhibition, the development companies demonstrated the so-called. nanostructured ceramic armor. Due to the use of special raw materials and special processing technologies, it is possible to manufacture ceramic tiles of various shapes and sizes that can be used as part of body armor or other similar equipment, as well as mounted on armored vehicles. Ceramic armor of this class has a fairly high protection performance, but differs in lower weight in comparison with steel armor plates with similar indicators. All this allows you to enhance protection without increasing the weight of the structure or to facilitate it without loss in the level of protection.

NEVZ-Ceramics (Novosibirsk) and Virial (St. Petersburg brought to the Open Innovations Forum several samples of ceramic armor made using different technologies and from different materials. First of all, these are products based on reactive sintered silicon carbide and boron carbide.This tile can be used in the construction of various products designed to protect people from bullets and shrapnel.


Ceramic Armor Tiles


According to the existing technology, ceramic modules of various sizes as well as with different protection characteristics can be produced. The ceramic block can be up to 205 mm in length and width. Module thickness is from 5 to 55 mm. Different dimensions of the tiles provide the flexibility of their use in the composition of various means of protection, and by selecting the desired thickness, you can meet the requirements for the weight of the structure and provide the desired level of protection.

The armored ceramics of the companies NEVZ-Ceramics and Virial may have different protection characteristics. So, as part of personal protective equipment, such as body armor, tiles can be used that correspond to 6 class of reservation according to national standards. This means that such a means of protection is able to withstand a SVD rifle (cartridge 7,62x54 R) when using a bullet with an armor-piercing core.

According to domestic media reports, Novosibirsk and St. Petersburg experts have already created more powerful armor ceramics, the possibilities of which exceed the protection against small arms provided for by domestic standards. Due to the use of appropriate materials and sufficient thickness, the ceramic block is able to withstand a shot from a weapon of caliber 12,7 or 14,5 mm. Naturally, such ceramics are not offered for use in body armor.

Such powerful protection is intended for installation on various vehicles. The company NEVZ-Ceramics together with the firm Kirasa (Perm) developed special mounted armored panels that can be installed on various equipment. A car or other equipment with such panels is protected from shelling using various machine guns or rifles, as well as from large-caliber weapons.

It is reported that the proposed hinged panels can reduce the overall weight of the equipment while maintaining the required level of protection against small arms. For this reason, they can be used in the construction or modernization of armored vehicles, armored personnel carriers, combat helicopters, boats or ships, as well as other equipment. Thus, perspective panels with ceramic armor can be used on techniques of various classes that require light but durable protection.

Currently, domestic enterprises are working to create new types of armored ceramics that differ from existing ones with special properties. For example, there is a project of ceramic armor capable of absorbing a radio signal. Such tiles will not only protect the equipment from bullets or shells, but also reduce the likelihood of its detection. The possibility of reducing the visibility of the radar is also able to protect equipment from weapons, which include radar homing heads.


Ceramic armor flap designed for use as part of body armor


It should be noted that NEVZ-Ceramics has been engaged in the subject of ceramic reservation modules for quite a long time. For example, in September last year, the participation of this company in several programs to create promising armored vehicles was reported. Then it was reported that the company completely switched to the use of domestic raw materials, abandoning its purchases abroad. In addition, some examples of the company's participation in promising projects were cited.

According to the words of the executive director of NEVZ-Keramix in the direction of “Armored vehicles” Vladimir Markov, it follows that ceramics of this company are equipped with Typhoon armored cars, Kurganets and Boomerang combat vehicles, as well as the promising Armata tank. State tests of armor ceramics as part of ready-made combat vehicles were planned for 2015 year.

V. Markov said that the production capacity of the enterprise made it possible to produce up to 650-800 tons of ceramic armor per year. Thus, the company "NEVZ-Ceramics" for the year can provide the necessary amount of armor up to one thousand combat vehicles.

The exposition of NEVZ-Ceramics, Virial and Breastplate enterprises at the latest exhibitions shows that they are ready to create and produce armor of new types not only for combat vehicles, but also for various personal protective equipment. In addition, Novosibirsk experts are engaged in another, no less important area. Using the latest technology, they are developing various medical devices. Special ceramics are used for implants, wear-resistant ceramic products and other products designed for non-military use.

    In fact, it is also surprising that in 1763 Lomonosov expressed the truth:
    “Russian power will grow in Siberia”. good

    Nanostructured armor - what a PR-commercial izb * b, because if you look deep into the structure, then at any object you can get to the scale of nanoscale.

      Nanostructured armor - what a PR-commercial izb * b, because if you look deep into the structure, then at any object you can get to the scale of nanoscale.

      To get this is one thing, and to achieve the formation of the structure of the material at this level is another.
      From, sorry, Wikipedia:
      Nanoceramics, as a rule, are obtained from nanoscale powders by molding and sintering. Since nanopowders are more difficult to compact due to high internal friction, pulsed and hydrostatic pressing, slip and gel casting methods, and hydroextrusion are often used to form them. One of the important problems in obtaining nanoceramics is usually the intensive grain growth during sintering under ordinary conditions. Two main methods are used to prevent it:
      Introduction to the initial powder (charge) of insoluble additives localized at the grain boundaries and preventing their growth.
      The use of special methods and modes of compaction and sintering of ceramics, which can significantly reduce the duration and / or temperature of the high-temperature stages of its preparation (pulse pressing, hot pressing, some types of low-temperature sintering). These methods are described in more detail in the article sintering of nanoceramics.
      The structurally sensitive properties of nanoceramics can significantly differ from the characteristics of traditional ceramics with micron grain size. It is possible to improve the mechanical (Al2O3), electrical (Y: ZrO2), optical (Nd: Y2O3) properties, however, the nature of the change in properties with grain size is very individual and depends both on the physical nature of the investigated property and on the physicochemical features used ceramics.

      * Nanoceramics (eng. Nanoceramics) is a ceramic nanostructured compact material created on the basis of oxides, carbides, nitrides, borides and other inorganic compounds, consisting of grains with an average diameter of up to 100 nm.

    It is not clear why they took silicon carbide from hot-pressed titanium diboride and boron carbide for armored ceramics - the criterion for armor resistance is 3 times higher and the ultimate strength is 300-350 MPa, compared to 200 for silicon carbide.

      And the price is 10 times higher and not technologically advanced in production. It always amazes me - if you aren’t doing such smart things yourself with ceramic armor, make armor from titanium diboride and tell us here in VO how good it is.

        I have another direction - the processing of materials, and also the calculation of the strength of parts. The price of boron carbide is 1,5 times more expensive than silicon carbide and is very technologically advanced in production.

    Honestly, it is not strong in carbides and diborides. But the article is interesting "+". And I'm glad for Russia, the main thing is not to stand still, and we are simply obliged to take care of our guys. hi

    Ceramic armor is marvelous as good, and relatively light, and technologically advanced in production, but the trouble is, at the place of the bullet, a significant portion of the ceramic is painted to the substrate, i.e. with each hit the protected surface decreases.

      So in the warehouse there should always be replaceable elements to replace damaged ones. Otherwise, the price of such armor is worthless.

    In 1942, the Germans thought of boron carbide.

    "Through the use of appropriate materials and sufficient thickness, the ceramic block is capable of withstanding a shot from a 12,7mm or 14,5mm weapon."


    What thickness? from what distance?


    I also wanted to read in the article what is the specific weight of the armor.

    So it does not matter. This is not a technical article. And so declarative.
    The actual problem is not in materials capable of withstanding a bullet, in the distribution of energy of this bullet for protection. For even if the bullet 14.5 does not penetrate the vest, the impulse that it will transmit to the body in the vest will not leave a chance for life. This is where the problems of bullet protection are well described. Http://army.armor.kiev.ua/hist/bronik.shtml

    Plates and for equipment are used. For armored personnel carriers and infantry fighting vehicles, for example, for the Mi-28. Therefore, resistance to 14,5 mm is important. At Nato, they wanted to take a 15mm machine gun into service, but something is not heard. Ceramics were made before, mainly ceramic balls for armor of tanks. If you take into account that under Serdyukov Israeli and German armored ceramics were purchased for trial, then after 2-3 years, you will get samples. We looked, shot and made an analog. From the Americans we buy high-density polyethylene for civilian body armor, is it interesting to do something in this direction?
