Everyone knows that it is easier to break up the usual string of sharp jerk. However, there is absolutely no other thread — high, in which a sharp impact force to the outer gap, including a speed of a bullet or fragment, greatly increases the strength (this is called dynamic strength). Only Russia has the technology of production of aramid fibers.
Fabric Rusar (sometimes called Arus) of these threads. It is used in the manufacture of personal protective equipment, and is recognized as one of the best specialists in the world.
It is from Rusar Center high-strength materials, "Armokom" manufactures adopted in 2008 the Russian army in the supply of combined arms helmets 6B7-1M.
Recently, the "Armokome" were able to improve the performance of this product, and so has an undeniable advantage in comparison with foreign counterparts to obtain a helmet 6B7-1MM. And same protective properties of its weight — only 1 kg!
— When we started the development of personal protective tissue of the discrete-armor, the high dynamic strength of manufactured "Kamenskvolokno" aramid fibers did not attach much importance — the general director of the high-strength materials, "Armokom", laureate of the State Prize of the USSR and the Russian Government Prize, Doctor of Technical Sciences, Professor Eugene Kharchenko. — For us, this property seemed a matter of course, the obvious characteristic of aramid fibers. The conclusion about the uniqueness of our aramid yarn made by American researchers, comparing it with the analogues produced in the United States. They were trying to understand why the body armor and Kevlar helmets are often inferior products from Rusar …
A VIEW FROM THE OCEAN
Customer survey made by the Pentagon in the person responsible for the equipment with U.S. Army General, Dr. James King Zenga. Opportunities to do so at the U.S. military was apparently abound — both financial and technical, and organizational. And in general the scale of military research in the United States stagger the imagination. For example, according to the Internet portal Defence Talk, only on the Office of Naval Research U.S. scientists work of the 50 states, 70 countries, 1,035 specialists of higher education institutions …
In a scientific paper, where the Americans have described the results of studies of the properties Rusar thread, it was stated that this thread on the dynamic strength surpasses the famous zaylon, not to mention the Kevlar. The authors wonder how soft textile armor panels of aramid yarn Rusar at the surface density of 27 per cent lower than that of Kevlar panels may have ballistic resistance is 12 percent higher. Such data were obtained in December 2007 in a test lab in Wichita, Kansas, USA.
In September and December 2008 were re-tested armor panels of yarn and fabrics Rusar of these threads of other parties. The stability test results remained at the same high level for the whole range of simulators fragments and bullets.
However, the outstanding properties of Rusar in America learned earlier than the above studies were carried out. Russian ballistic fabric fibers Rusar been repeatedly tested and in other American, as well as in the British and German laboratories that showed record results in comparison with the best foreign analogues.
Perhaps that is why firm "Alkema Technology", which is marketing research on foreign ballistic market, assumed ballistic products from yarn Rusar brand AuTx (Auteks). Aurum (Au) in Latin — gold.
Naturally, the western producers aramid fabrics immediately defended the reputation of their product. In 2006, the manufacturer of Kevlar company "Dupont", and in 2008 — the manufacturer of Twaron company "Teijin Aramid" tried hard to convince the experts in ballistics instability and adverse side effects Rusar. However, scientists from the University of Leeds (UK) came from research to a different conclusion: the thread Rusar 2-2.5 times more stable than Kevlar and Twaron.
What has not made the researchers to compare the American and Russian aramid yarn. Even boiled in water for 300 hours? So long boiling downgraded the initial strength of Kevlar and Twaron to 60 percent, while the Rusar — only 10 per cent.
In October 2007, aired on broadcast TV channel "Discovery" on how the United States are manufactured and tested police body armor. Ballistics expert largest American company manufacturing facilities armor Armor Holdings Bruce Weber told what materials are used in the creation of means of body armor. Describing the design of the most effective line of body armor ABA, the developer showed Russian aramid twill and confirmed the use of Russian-made aramid fabric AuTx.
How does our fabric was in the U.S. for the supply of the police?
According to official data of the Federal Customs Service of Russia, the Russian export of aramid fibers was 30.3 tons in 2006, 54.1 tons in 2007, 22.5 tons in 2008, 23.8 tons in 2009. And in 2010, and the first 11 months of 2011, shipments also exceeded 20 tonnes lion’s share of fibers acquired the Italian company Pro Systems for its processing in ballistic fabric under the brand name Artec. Artec then become the leading manufacturers of personal protective equipment in the United States, Israel and several European countries and use it when making equipment, so to speak, the elite class. And by the way, point to the use of aramid fabric Artec in the top line of their products on their own web sites.
Ballistic armor materials based on Rusar tissues were submitted to tests of a new modification of the main U.S. Army body armor type JOTV and showed an advantage over regular material in a wide range of attack — from 10 to 16 percent. And only by U.S. law known as "limiting Bury", this Russian material does not become the object of exports to the United States. That’s why some general Zeng and had any way to reveal the secret Ru
"How did it Russian? — Wondering, perhaps, General Zeng. — How they managed to get such fantastic results? Due to the yarn, weaving, or a combination of both, plus the design itself armor panels? "
I do not know whether the U.S. received a general answer to these questions. In any case, such as magnificent as Rusar, materials, branded Made in USA has not yet appeared. And Russia is clearly the leader in the manufacture of personal protective of Rusar. This is confirmed by the results of our tests.
CHECKED IN RUSSIA
So, on the Rzhevsky range in 2009 tested several types of helmets manufactured in the USA, South Africa and 4 combined-type body armor manufactured in the USA, Ukraine, seized as booty in the Caucasus in August 2008. Tests have shown that the combined basic characteristics of domestic helmets are not as good as foreign, but the researchers noted a large area of protection and lower weight of domestic first-generation composite helmets taken to supply about 15 years ago.
In 2002, the research center of Natick were developed and adopted by the U.S. Army composite helmets are the latest generation Advanced Combat Helmet (ACH), which were to replace the helmet PASGT. Bulk purchase of helmets began in August 2005, and to date, these helmets were purchased at least 900,000 units. ACH helmet is made of a new type of aramid fiber Kevlar, which provides enhanced ballistic and impact protection. The tests, which were carried out by our experts show that the helmet withstands 9mm pistol bullets at a speed of 442 m / sec and has a top anti-shatter resistance among peers (according to some estimates, up to 739 m / s). Moreover, ACH somewhat easier PASGT — the weight of 1.36 kg.
However, it does have one major drawback: 8 percent less area of protection than the PASGT, for which U.S. military experts are subjected to serious criticism of this product. The main disadvantage of the new helmet they believe large openings in the rear and sides of the head, which may lead to an increase in brain injury by 30 percent. According to a credible source, in just one hospital in Iraq has been 160 U.S. troops with such wounds.
Similar deficiencies and has the latest Israeli helmet R-ACH, which is at a slightly lower weight, 1.3 kg, has an area of protection is not more than 10.5 dm 2 and ballistic resistance of about 670 m / s.
In the shelling of the helmet PM pistol and a standard simulator fragments weighing 1.1 g occurs very significant damage to cover and camouflage, and the outer layers of the protective structure. At the same shelling domestic Slam 6B7-1M damage is much less.
In recent years, an unprecedented boom raised around the French military kit Felin. Protective helmet of this set is also studied our experts — item by item at the MAKS-2009. And found out that it is made of a composite based on polyethylene fiber, has a larger area of protection than the U.S. ACH (about 12.5 dm 2), but has less than ACH Ballistic resistance — 680 m / s. The main drawback of the helmet Felin than the best domestic helmets 6B27 and 6B7-1M facing the Russian Army, is significantly less protection side view of the head.
In accordance with the instructions of the Chief of General Staff of the Armed Forces — First Deputy Defense Minister Army General Nikolai Makarov, the General Command of the Army together with the concerned military authorities recently conducted benchmark tests military equipment of domestic and foreign production. To carry them out Russian defense enterprises has provided more than 200 samples. Tested and 41 element combat equipment, standing on the supply in foreign armies. The performance characteristics of the products tested in the course of combat training, and on the basis of laboratory TSNIITOCHMASH (Klimovsk). Of course, were evaluated including helmets — both in terms of ease of use, and on bulletproof. Checks showed that foreign PPE compared with domestic have the same protective properties. The mass of the domestic body armor to 2 kg, and helmets — 300-400 grams less.
In addition, foreign helmets has identified a number of operational
shortcomings. In the bindings used plastic and metal items that relate to the person that the low temperatures will lead to frostbite of the skin. Helmets used in the U.S. and Germany podtuleynye devices do not provide enough ventilation podtuleynogo space.
— The results of serial testing helmets 6B7-1M our specialists have improved, — the "Red Star" head of the testing laboratory of the Centre "Armokom" colonel Oleg Faustov. — The new combined-arms helmet 6B7-1MM for the "Queen of the fields’ infantry and other combat arms has a special fastening system for the installation of radio and navigational equipment, video and infrared cameras, night vision devices and others, it is more convenient adjustable podtuleynoe device. In addition, and same protective properties, it has become even easier. At three product size while the helmet weighs small than 1 kg! Finally, in contrast to our foreign helmets has buoyancy, i.e. does not sink in water.
Recently, our defense industry places a lot of complaints — and the technical characteristics of the products produced by it, and their cost. Many of them were well-founded, because buying for the Army and Navy models of equipment and weapons yesterday and even at a higher price — so damage our defense.
However, it would be a great mistake to believe that our "defense" has nothing on earth can do. Developed under the guidance of Professor Kharchenko helmets and other personal protective equipment, including the unique fiber-composite materials based on Rusar, we can be proud of. These products — by the way, to protect counter-terrorism operations and special forces of the FSB of Russia — the highest order!
