Body armor made of polyethylene is not inferior in strength to steel

Production of new body armor with inserts of high-modulus polyethylene was established in one of the capital's research institutes. To demonstrate the capabilities of the new protective equipment, the developers conducted its comparative tests with armor steel. As a result, plastic plates stood the shot of a Kalashnikov assault rifle and a Tokarev pistol from a distance of five meters on par with metal ones.

"Polyethylene can compete with the best brands of armor steel. For example, with materials such as titanium and aluminum. In addition, it is lighter than double," - said RIA News representative of the developer of body armor Evgeny Chistyakov.

According to experts, in the near future this material will completely replace armor steel from personal protective equipment. According to research institutes, the US Army has gradually begun to abandon Kevlar helmets, replacing them with polyethylene. Also, this material can be used in aircraft as an additional protection for the pilot and even mounted on armored vehicles.

Combining high modulus polyethylene with special ceramic plates increases the strength of body armor. In this case, he will be able to withstand even hit an armor-piercing bullet, the developers say. However, the novelty has a drawback: the material loses its protective properties at a temperature of more than 140 degrees Celsius.

As the representatives of the company noted, the material for the production of body armor made of polyethylene is now being purchased abroad. However, according to the staff of the institute, the production of domestic analogue will be established during the 2011 year.

Well done! Although it is, they will do it with us. Do not sponsor the bourgeois figs!

Kevlar is not really steel. This is a para-aramid fiber from the American firm Du Pont. Equal weight Kevlar fibers are five times stronger than steel. And when the fibers of the body armor are glued in a certain way, when a bullet hits, it is not destruction, but on the contrary, the strengthening of the fibers at the point of impact of the bullet. Likewise, "polyethylene" for armor is not exactly polyethylene. Protective helmet "Sphere" made of Kevlar also does not always save. When a bullet hits it, there is no hole, but the impact due to the kinetic energy of the bullet is such that it can break the cervical vertebrae, taking into account the severity of the "Sphere" itself. And if you shoot at close range with a 7 mm machine gun, then the holes in the armor are not needed. A person will also die from a painful shock! Imagine if you are beaten on the naked body with a sledgehammer! What is it ?!

withstood the shot of a Kalashnikov assault rifle and a Tokarev pistol from a distance of five meters along with metal ones.

Since when did the metal armor keep the AK from 5 meters, or is this armor made on the basis of decommissioned T-34 cases?
Well, about kinetic shock Stavr rightly said, if a metal helmet for example has a chance to ricochet a bullet, then the polymer absorbs all energy almost always, and even a pistol bullet of a normal caliber has enough energy to break its neck. However, he held in his hands and wore an American polymer helmet a little on a Bosko, he has a fairly loose suspension, this improves ventilation and probably does not allow the energy of the bullet to immediately pass to the head. On the other hand, the question of price is possible, because Kevlar is a very expensive material, possibly high-modulus polyethylene is cheaper. Now the Yankees are also trying to adopt a polyethylene helmet and seem to be close to this, they have a requirement that it does not break through with a standard AKM bullet from 50 meters (so as not to lie).

It is interesting where on earth such temperatures? Or is it necessary to beat incendiary or armor-piercing incendiary armor?

[Superduck]

cumulative does not hold

However, the novelty also has a drawback: the material loses its protective properties at a temperature of more than 140 degrees Celsius .-- with this t ... e, those who are wearing this vest are already all the same, the dead do not sweat.

[Cap-3 USSR]

140 is not such a high temperature. In the inside of a burning room, the temperature can be 150-200. And for some time you can be there. The question is how quickly at 140 this bronik loses its properties. If at once, then this is one thing, but if in 15-20 minutes, then another. Fire robe is designed to hold up to 400, and a reflective suit up to 800 degrees.

[Superduck]

maybe an inaccurate translation and it was about degrees Fahrenheit, and this is 60 Celsius, which is really not very good

[PSih2097]

not, in Celsius, just an example - we take a packet and shove it into boiling water, but here we are talking about a highly modular, i.e. a bunch of additives, IMHO type of substrate for thermal insulation.

[fantast]

Very similar to fake.
It seems to me that idle shot

[Bururuz]

one thing is interesting to me, since when did the bronchists postpone hit from the Kalash from five meters?

I wonder why to buy polyethylene abroad, when in Russia you can collect it anywhere. Just go to a local park or forest.

Themselves answered their own question, why collect it, because it’s easier to talk Russia and feed foreign friends

Is there a civil option? playing a square is sometimes a painful topic that will prevent lying.

[Evgen232]

However, the new material also has drawbacks - it breaks if you poke a finger. Buy "our" bulletproof vests made of polyethylene. And "comrades from the west are not capable of anything when there is not enough money.

The soldier also loses its properties at 140 degrees))))
