To replace the "Ratnik" outfit: in Russia, heavy-duty polyethylene has been created, which is applicable in body armor

In Russia, a special super-lightweight and super-strong material has been developed. It is planned to make it the basis of promising means of protection against bullets and shrapnel for military personnel.


We are talking about the so-called ultramolecular polyethylene, the plates of which will become the basis of the body armor. The material is lighter not only than metal, but also Kevlar-based organoplastic used in the creation of American body armor. At least that's what they write in the departmental publication Krasnaya Zvezda.

It is indicated that the latest Russian material is able to withstand a direct hit of small arms ammunition weapons or a fragment moving at a speed of up to 670 m / s. This is significantly higher than the indicators of the mentioned American organoplastic (its limit is 480 m / s), as well as the Israeli material, designated as UD (up to 630 m / s).

The Russian supermolecular polyethylene is planned to be used in the creation of body armor, which will replace the set of military uniforms (equipment) "Ratnik".

According to the latest information, the new material is named "Super Thread". The first bulletproof vests, which are being tested, have already been produced on the basis of Supernity. Taking into account these tests, a conclusion will be made about the optimal thickness of the plates from the new version of polyethylene for various protection options.

It is especially emphasized that the new body armor can become the basis of protection for the marines, as the feature of the "Supernity" is also in the fact that the material is able to stay on the surface of the water.

With the active introduction of body armor based on such material, the load (by weight) on the fighters during combat (combat training) operations can be significantly reduced, which means the fighter saves energy, and therefore the ability to maintain combat effectiveness longer.

    As I understand it (I read somewhere yesterday), polyethylene is a binder.
    And the thread is polyamide.
    Or is it a polyethylene thread?
    What then is she filled with? Not soft vests.

    If the weight parameters of the journalist were not wrong, then the step forward is simply huge!
    Good luck to our chemists!

          It all depends on the volume.
          If you produce dozens, then one cutter will be enough.
          If thousands - small mechanization will be required.
          If you want to see a production line, the output should be in the hundreds of thousands, which implies the export of most of the products.

          It's not about the cutting machines. Ultra-high molecular weight polyethylene is an extremely difficult material to process. Plain polyethylene is melted and drawn into strands and films. With ultra-high molecular weight, this number does not work: it softens at a higher temperature and at the same time undergoes destruction, losing its valuable properties. This material has been around for quite some time since the late fifties, but it was recycling problems that slowed down adoption.
          The processing is simplified as follows: the material is dissolved at high temperature in a suitable solvent with a high boiling point, such as diesel fuel or decaline, then cooled (which forms a gel) and extruded through dies. A heavy solvent is replaced with a low-boiling one - for example, heptane, by exposure in this solvent, then new extractions are carried out, drying and again extraction. Obviously, production is both complex and requires a huge amount of solvents (which must be recovered by distillation). Hence the low (so far) production volumes and, probably, the high price. But the material is extremely interesting - both in strength and high modulus of elasticity, and lightness, and chemical resistance, and a low coefficient of friction (lower than that of Teflon!), And an unlimited raw material base, and therefore it is guaranteed to find many applications. And what kind of line would come out of him!

          Aramid material (kevlar) is being cut in the picture, the article itself is for elementary school and the title is silly. The warrior is a set of head to toe protection + appropriate wearable personal equipment and equipment places. And, UHMWP are armor plates with a thickness of 10 or 20 mm, which are inserted into the pockets of body armor instead of steel or an aramid (kevlar) package. Therefore, colleagues, be critical of the efforts of the copywriter. UHMWP has advantages over aramid. It is lighter and is not afraid of moisture. There are downsides. Aramid keeps normally at + 300C, UHMWP loses its protective properties at + 100C. UHMWP plate 20 mm thick, holds only PM and 12 caliber hunting rifle. therefore it is used for body armor of cash registers or police. For an automatic bullet, 5-10 mm ceramic plates are placed in front of the UHMWP (aramid, kevlar). thickness. This is called an army-style body armor. A layer of 20-25 mm thick ceramics is placed on the BMP armor, sometimes with an aramid package. UHMWP is not used (burns). This sandwich holds a 12,7 mm armor-piercing bullet. Therefore, UHMWP and aramid are called a substrate and serve only to stop fragments of ceramics and the remnants of a bullet destroyed by a ceramic layer.

          In the photo, an armor-piercing incendiary bullet of 12,7 mm pierced the ceramic layer and got stuck in the UHMWP, melting it with an incendiary composition.

            In the photo, the bullet came from the right side. The pottery is visible, it is white, cylindrical in shape. UHMWP layer 20 mm thick, raised. The remains of a bullet are visible in the crater. The armor-piercing core of the bullet fell apart from the impact on the ceramics.

      To replace the "Ratnik" outfit: in Russia, a heavy-duty polyethylene used in body armor has been created

      The "Warrior" set is not so bad and oldto change it so soon and at a cost, by the way yes ... We need to talk about the modification (modernization) of the newly produced kits, since the new polyethylene has shown itself so well.

      From my experience of contact with polyethylene as a protective material, I want to note that I was not impressed by the Ukrop trophy "polyethylene" helmets No. (I already wrote about this).



      The shelling of such a helmet from the RPK-74 showed that the helmet is "stitched for flight" from all distances, and the "filler" sticking out of the hole rather resembles layers of stretch food-grade plastic wrap, in which food is wrapped for storage ...

      That is why, although at that time we did not have much with Kevlar, none of ours was tempted by such a "super helmet", limiting himself only to picking out the harness from them in order to "integrate" it into the old grandfather school.

          The result is on the face (photo). And 5,45 leaves just a small hole, with a chipped outer "shell", from under which layers of polyethylene can be seen.

            If you google, you will notice that Kevlar has different colors and thicknesses of threads. Depending on the country of origin. I am far from thinking that dill made their helmets from Russian aramid.
            Secondly, you posted information that the shelling of this "miracle" was carried out from a machine gun. If I'm not mistaken, the muzzle velocity of the RPK, PKM bullet is higher than those stated in the article. So try adding two and two.
            I'd like to add that I had to try on Kevlar and polyethylene helmets at the exhibition for three years. The difference in weight is palpable. I already wrote about this. Dig into my old comments, you love that.

        Here you need to understand the details. The article says about the speed of bullets and fragments, withstood by the material, up to 670 m / s (again, how thick is the layer of material that can withstand it?). The RPK-74 bullet flies at least 950 m / s even from a worn barrel. Therefore, the result of your tests is logical, even if we assume that the quality of polyethylene is no worse than Russian. And then there is another nuance - "small arms ammunition" - a very extensible concept. 7H10 from AK-74U is not equal to 7H24 from AK-74M, and even more so is not equal to 7,62x54 from SVD. And this is all small arms ammunition. The article is more advertising ... details are not enough to reason here.

          In addition, in a NATO, battered Kevlar helmet, a bullet "on exhaustion" was fired from either the PKK or the AK - "stuck", but the Okrainskiy one in polyethylene is NOT.
          From the grandfather's school there is an option that it will rebound - polyethylene - NO.

            Yes, I read carefully what you wrote. Your (or Ukrop) experience of shelling a helmet confirms my understanding of reality :) And it is such that it is fundamentally impossible to create a material and a helmet from it, allowing a fighter to survive even a 5,45 bullet hit at an angle near the normal (90). It will either be very heavy and break the neck without breaking, or it will break through at such angles of impact. Therefore, there are such "streamlined" formulations about "small arms ammunition" without specifying the caliber, bullet weight, and angle of impact.

      No, this is ultra-high molecular weight polyethylene (UHMWP), the technology for producing ultra-strong UHMWPE fiber was developed using domestic UHMWPE powder produced on the IKT-8-20V catalyst at the VNIISV pilot plant (Tver) in 2007. Its specific strength reaches 350 gf / tex, which is almost 1,5 times higher than that of the best Armos / Kevlar aramid fibers. The problem was in binders that could glue the UHMWP fiber into a single composite. Only in 2020, the specialists of the Armocom Center and the Central Research Institute of Special Machine Building (Khotkovo) managed to develop a composite composition based on UHMWPE fiber and, which is very important, a technology for molding not only flat, but also curved products from polyethylene composite.

        There are many directions for improving individual body armor, I considered them here:

        In the foreseeable future, the effectiveness of the main small arms of the Armed Forces will greatly decrease, and the effectiveness of weapons capable of engaging with small fragments, such as grenade launchers or AGS, will decrease even more.

        No wonder the United States attended to the NGSW program

        We also need to move in this direction, for example:

      UHMWPE is not a novelty in the world at all! It has been produced, as they say, not for the first year! Here are some data on the production of UHMWPE in the world ...
      World manufacturers of UHMWPE

      Celanese Corporation (USA), Braskem SA (Brazil), DSM NV (Holland) and Mitsui Chemicals Inc. dominate the global UHMWPE market. (Japan). Celanese, with production units in Oberhausen (Germany), Bishop (Texas, USA) and Nanjing (14 thousand tons / year, China), has the largest capacity in the world for the production of UHMWPE - 108 thousand tons per year. The second behind Celanese is Braskem, whose capacity amounted to 45 thousand tons in 2018. Both producers account for more than 60% of all world UHMWPE capacities

    It seems to me that there are sanctions for the supply of various polymers to the Russian Federation, ranging from composites for the aircraft industry. They started to give effect)))

      UHMWPE (Ultra High Molecular Weight High Density Polyethylene) began to be produced already in the 50s. the title hints at new material when in fact it is a modification of the old one.

        In Russia, a special super-lightweight and ultra-strong material has been developed ...
        We are talking about the so-called ultramolecular polyethylene

        A good invention, only it was really made in the 50s of the last century. UHMWPE has been used in industry for a long time. True, it is still very expensive, so it is used only when absolutely necessary.

          Invented in the 50s, the fibers were obtained only in the 70s. When was it brought to mind? It is not clear at all. And not the point, the point is. that with the sanctions we have begun to stir - and the composites for the aviation industry - our own, and the bulletproof vest, which the "inventors" do not have

        Minus. Making polyethylene is one thing, but converting it into products is another. The processing methods used for ordinary polyethylene are in principle not suitable for UHMWP.

      No, the material was developed in 2007 at VNIISV, and only now it suddenly turned out to be necessary.
      I am already writing an article on super strong high modulus yarns and fibers and ballistic fabrics and composites made from them.

    Great! I'm sure that in the national economy, so to speak, the material would be useful. The Chinese and Americans periodically introduce military developments with great success into the domestic sphere and make a good cash register, plus not weak PR for their military-industrial complex and science into the bargain.

      Would come in handy of course. At one time, the SVM thread produced at Kalininsky Khimvolokno and the fabric from it went to the cord for car tires, but things did not go further than experimental batches. And out of 6 factories and pilot plants, we now have an industrial scale aramid thread and fabric produced from it only at Kamenskvolokno. The TsAN workshop in Tver was warmed up in 2008, and before that they were suing Alfa-Bank, they fired 250 people at once, then the fire was restored according to the court. There is no more production in Tver. And at the VNIISV pilot plant, the production of UHMWP fiber is 5 (FIVE) tons per year.

      The trick is that the United States has a much greater industrial and technological potential. At one time, when I visited VNIISV on the PAN thread, I was told that the shop was closing (Rostec came), and most of our production was pissed away in the 2000s. Fortunately, such production remained in the Republic of Belarus, so for now we have something to make carbon fibers and composites from them. The Argon plant in Balakovo used a viscose fiber precursor that was produced at the Balakovo PO Khimvolokno named after V. IN AND. Lenin, but the latter was declared bankrupt in 2004 (if memory is not changed), the largest production of hydrated cellulose fibers and threads in Europe. Our Sibvolokno was in second place, in the 80s they made up to 65 thousand tons per year, a plant was built nearby under the code "Viscose-85" for the production of SVM thread for the defense and aerospace industries. But in 2005, the end came to us, although in fact much earlier.

    In the early 90s, Kevlar thread appeared in Russian fishing stores, which was very popular with spinners who were not spoiled by abundance. I liked it until foreign counterparts appeared. Well, when in the early 2000s there appeared Dupont and YGK-shny "threads" made of high molecular weight polyethylene, Kevlar finally migrated to the area of ​​fishing jokes. After another 20 years, we read about the emergence of technologies for the production of PE-filament in Russia. Whether it is foreign or worse, we learn from the same fishing shops.

      ummm .... I think it's not worth comparing them and our threads, but the previous technology of manufacturing personal protection and the new one. If there is an increase in penetration resistance against the background of a decrease in weight, then isn't the rest important? After all, not a fighter with a new body armor will not go fishing

    We are talking about the so-called ultramolecular polyethylene, the plates of which will become the basis of body armor. The material is lighter not only than metal, but also Kevlar-based organoplastic used in the creation of American body armor.

    When I read articles with such material, my heart begins to beat faster - the Russian heroes have not yet died out on the earth, the minds have not become scarce, skills and dexterity have not been lost.
    There is an article where:
    US Army and Police officers wear heavy, rigid body armor for protective purposes to provide adequate protection. However, the silk of the Madagascar spider is 10 times stronger than Kevlar, the material used in most body armor.
    If it was possible to invent a method for the production of spider silk on an industrial scale, then body armor would be made of lightweight, heavy-duty material that can reliably protect the body from bullets and shrapnel.

    Isn't this the way our developers went to create an artificial web?
    You know, every time peeling onions, I am amazed at how difficult it is to cut its dry husks. Cutting a tomato with a not quite sharp knife is also problematic. But, there are people who not only notice such features, but also apply these properties in practice ...

      At one time I read about experiments on the genetic modification of goats, which were "grafted" with the spider gene, which is responsible for the production of the material of which the web actually consists.

      Why goats? It's simple ... Scientists intended to isolate the substance of the spider thread from the milk fed from goats ...

    The Russian supermolecular polyethylene is planned to be used in the creation of body armor, which will replace the set of military uniforms (equipment) "Ratnik".

    Previously, it was bought for armored vehicles (Police) in Dupont .... but for the army they could not buy it.

    Let's hope that ours will succeed. And the first armor was certainly not very good. Before Chechnya, I took out the plate and checked it at the shooting range from 5,45 mm, from 100 meters right through. So, I did not take him to the mountains - no sense and a serious infection. But sleeping on it was comfortable, you open it like a cradle and you can throw it into any dirt, felt inserts warmed your back well even in winter. And then, like Cuirass, they went, those were already credited, they held a bullet point-blank and even became easier.

    Is it really that hard to make a cutting machine? It's elementary!
    Savings everywhere. Economists, damn it. Then they wonder why the product is not competitive.

    Will go into series, then machine cutting will appear. Until then, manual testing is enough.
