In Russia, developed armor of nanostructured ceramics and silicon carbide

The Open Innovations Forum hosted a presentation of the unique developments of the Russian companies NEVZ-Ceramics and Virial - armor made from nanostructured ceramics and silicon carbide, which has the highest protection class, in particular, can withstand the impact of the Dragunov sniper rifle (SVD) writes "Russian newspaper".

Nanostructured ceramics, which produces Novosibirsk "NEVZ-Keramiks", is used to protect vehicles and personnel of the Russian army. Such armor has less weight and increased efficiency compared to traditional materials. The armored ceramics was successfully tested in the Russian Federation and abroad.

This material is used for the manufacture of mounted composite armored plates that provide protection in 6 class, including from fire from a SVD rifle, as well as from armor-piercing and incendiary cartridges of large-caliber machine guns.

According to the manufacturers, the use of new mounted armored panels significantly reduces the mass of armored personnel carriers, armored cars, ships, boats and military helicopters and other special purpose vehicles. In addition, armor ceramics with radio-absorbing properties are already being created to provide masking from detection tools and missile guidance heads.

The St. Petersburg company brought to the exhibition armored elements made of silicon carbide, designed to protect military land equipment, ships, aviation equipment and personnel. Armor plates up to 205 mm wide and up to 55 mm thick can also protect against SVD bullets.

[Lord of the Sith]

And what weight, for example, is 10cm x 10cm?

[Baikonur]

Also immediately asked this question! And it is unclear what is better than an armored steel (for example, its 55mm thickness can withstand not only SVD!) It is a comparison of the most important thing - the masses, which is not given in the article, although the article is about it !?

[Juborg]

Baikanur, you didn’t wonder, what is the bulletproof steel not heavier than usual and much harder than ceramics? In addition, AUTO made of armored steel, weighs a lot than lined with removable and removable ceramic panels. As far as I understand, the new panel is lighter, stronger and cheaper to manufacture, but we are unlikely to know how much this is all true.

[GDP]

Ceramo armor has one drawback - it breaks ...

And the thickness in 5,5 cm to withstand a bullet from a rifle - something is not enough for innovative armor ...
10mm steel is enough to protect against SVD. And then brittle ceramics and 5,5 times as thick ...

as far as I know, ordinary ceramic armor with a thickness of 20mm holds an armor-piercing bullet from a Kalashnikov assault rifle almost point blank ... And here, an innovative one for protection against a rifle requires 55mm!

The mass of ceramics armor is two to three times less than steel, that is, it turns out that with 55 mm we get a mass of one and a half two times more than the frontal armor of an armored personnel carrier ...

What is the innovation of this super nano armor ?!

Something got mixed up with numbers as it seems to me ...

[Vadim237]

Steel is 3-4 times heavier than carbides. 55 millimeters is not a typo.

[Ratmir_Ryazan]

On account of the fact that it’s unlikely to be easier to manufacture ... The 6B13 body armor quite modern began to enter the troops only somewhere in the year 2006, now it costs about 13 rubles at retail, and one ceramic panel for the 000B6 body armor is about 43! !! And the bronik itself in a complete set is closer to 30 000 rubles !!!

most likely a mistake - not 55mm, but 5.5mm - otherwise armor plates are not obtained, but armored parallelepipeds)))) 205x205x55

[Good me]

Armor plates up to 205 mm wide and up to 55 mm thick can also protect against SVD bullets.

Five and a half centimeters ... On a bullet of SVD (7.62X54), even armor-piercing ...

And for "Cliff" (12.7X108), what is the thickness of the armor plate?

[Kostyar]

The article is about nothing, noted .............

[chunga-changa]

An article about nanonews. Chubais is strengthening the country's defenses, somewhere else there should be nanopatrics.

[g1v2]

The company NEVZ-KERAMIKS CJSC was established in 2011 as a result of the signing of an agreement between HC NEVZ-Soyuz OJSC and RUSNANO OJSC on the creation of a joint venture for the production of nanostructured ceramics.
Well, since Chubais is involved in the production of this ceramics, it is not kosher to use it for the right patriots. After all, all the right patriots know that this is a cut, but they say that they make armored ceramics, for example. These are all bullshit. Since racially correct patriots said that this is a cut, then how can they not be trusted?

In fairness, it is worth noting that there are a lot of such enterprises launched by Rusnano, of course, not everything is successful, but this is normal. After all, high technology is a risk, and even in the absence of a guaranteed sales market, well, there is a financing problem, therefore, the development of complex technologies is not within the scope of private business alone. That is why the idea of ​​creating Rusnano is magnificent and only true !!! Where state guarantees and support, initial state orders, soft loans with the attraction of business funds including Western technologies are combined, all this is the key to the success of future enterprises, which means the development of high technology, import substitution, independence, including in the military-industrial complex. Everything else, myths invented by pests for idiots so that they would not believe in their country even more. And on the account of Chubais, for the survival in the world of business sharks, a pack of seasoned wolves is more suitable, rather than a choir of Nanai boys.

A cliff with armor-piercing T 72 sews to the side of the tower. In 1995 in Grozny there was such a problem.

[swan]

It is also formulated so that a campaign, a larger plate can no longer stand =)

Quote: Sith Lord

I know for sure that the density of armored ceramics is lower than the density of steel by about 2-3 times, respectively, and the weight of the plate will be as much less than the same steel.

[i80186]

Quote: Sith Lord

And what weight, for example, is 10cm x 10cm?

The density of silicon carbide is 3,21 g / cm ^ 3, and that of steel is 7,68 g / cm ^ 3. That plate, about which they say (205 * 205 * 55) - 2,3 kilograms weighs. Steel would weigh six. But something tells me that not every projectile will pierce 55mm steel, and not that a machine-gun bullet.

[2s1122]

It doesn’t indicate from what distance they fired on these plates, maybe they fired at an emphasis from the SVD :-) here the thickness of the plate was 55mm

[Nikolay K]

Pay attention to the shape of the plate. Width 55 mm is the maximum (in the corners), in the central part of the plate is two times thinner. Accordingly, the weight is less.

She has a density of 2,55 grams per centimeter cubic - you need the volume of the block, multiply by the density and get the mass.

Until it passes military tests and is not accepted for use, there is nothing to talk about.

[Thronekeeper]

For commercial purposes (booking personal cars and bank cash collectors), as well as to improve the booking of helicopters and armored vehicles, silicon nitride and silicon carbide with fiber reinforcement has been used for a long time. I was surprised that a 55mm plate is presented as GOST 6a class. BB 12,7 / 108 such a socket should hold. Tiles are clearly intended to be set, not NIB. However, these two layers cannot be stolen in a checkerboard pattern; there should be no gap between them.
There is little information in the article. In what sense is it "nanostructured"? With its own fibers, or as a polymer, for lighter weight and greater ballistic resistance, or as a pseudocrystal?

I know that Typhoon has dispersed ceramic armor. I also know that in the photo in the article there are ceramic tiles presented 3 years ago and already tested and used in prototypes of armored vehicles.

Bulletproof vests of protection class 6a.

The last class of body armor in accordance with domestic GOST is class 6a, the latest in the table of Russian GOST for classification of personal protective equipment. GOST requirements for class 6a are as follows:

The bulletproof vest should not be pierced by the B-32 armor-piercing incendiary bullet of cartridge 7,62x54 (GRAU index 7-BZ-3) weighing 10,4 g with sharp steel hardened cores of high-carbon steel, flying out of the barrel of the SVD rifle at a speed of about 830 m / with and falling into body armor from a distance of 10 meters.

As a rule, such body armor, classes 6 and 6a, are very heavy. Sometimes an apron with a hefty ceramic plate, designed to stop sharp heat-strengthened cores made of high-carbon tool steel (for example, such as U5A) armor-piercing and armor-piercing, is hung on top of an “anti-automatic” protective kit (for example, a 10th-class bulletproof vest with large area armor plates) incendiary bullets of special cartridges.

Such bulletproof vests are used for short-term assault operations, where the unit needs to go a certain distance under the fire of army small arms (machine guns), machine guns and snipers. The constant wearing of such personal protective equipment is impossible, both because of excessive weight, and because of significant difficulties in thermoregulation of the body and the inability to properly sit down, lie down, stand up and bend.

[Same lech]

anyone interested .... see.

[hydrox]

Unconvincing.
Where can I see that this is exactly the NANO metal ceramics that was announced at the presentation? The size of the plates does not match - no other data is given. Or is it the same material that has been tested ABROAD?

[Mountain shooter]

Of course, the thickness of the ceramic required for protection against SVD is significantly less than 55 mm. The specific gravity of such ceramics is about 3.5 g / cmXNUMX, which is two and a half times less than armor steel. The main problem with ceramics is how they withstand multiple hits. Otherwise, it will crumble to pieces, and that's it, there is no protection, with the second or third shot - the target is hit. This "nanostructured" one should help in this matter.

In general, everything is written about the properties here ...

In systems with dispersed zirconia particles, unique materials are obtained having a bending strength higher 1500 MPa and crack resistance K1c more 30MPa (m1 / 2)...

[Vadim237]

For armor, tensile strength and toughness are most important.

[Massik]

protection class 6a, including from fire from an SVD rifle, as well as from armor-piercing incendiary cartridges of heavy machine guns

ummm ... no further name could go on.

[brn521]

from fire from the SVD rifle, as well as from armor-piercing incendiary cartridges of heavy machine guns.

A strange mixture of some kind. Still and guns here to the heap.

unique developments

What is unique is not said. Ceramics in body armor 15 years ago held armor-piercing rifle bullets at point blank range. Another thing is that this business was expensive, and the manufacturing technology was not stable. Because of this, ceramics were abandoned in most cases.

[Zaurbek]

In the states, they also make bulletproof polyethylene. Dupont sold them to Russia for body armor.

[2s1122]

The classes of defense are different for us and for the USA, it’s one thing for a policeman to fly and a completely different thing for military men. I’m silent about special forces.

[Igor Olegovich]

And what is the thickness of ceramics needed against a tank shell?

[imugn]

Three times in the article it is written about protection against SVD.

Thank you Same lech for useful information

[Riv]

It has already been said that the bulletproof vest of such elements will be very heavy. You can’t even imagine how much. Actually, the three of us will have to wear it and we will also have to attach the wheels so as not to get tired very much. Ceramic brick 200x200x50 mm in size is quite heavy, yes ... And fragile - this also cannot be taken away from it, no matter what nanomaterials it is made of.
Finally, the most important thing. Let's say this brick can withstand a large-caliber bullet and will not fall apart. What difference does it kill you: a bullet, or this brick? The law of conservation of momentum has not been canceled. A brick with a pulse of half the pulse of a bullet will kill no less reliably.
And in my starting photo, in my opinion, heat-resistant lining elements are depicted. They have nothing to do with armor.

[mAgs]

And you, what, did not know? According to the new rules, the developer of such products is directly involved in the testing of samples, if it survives the test, it means it is accepted for operation. Just kidding of course, just in your comment so much skepticism. With respect.

[Riv]

Of course. I know what an ordinary 5,45 bullet does with a helmet. And the large-caliber ... :) But the faith of hamsters in science is unlimited.

[mAgs]

Yes, Riv, you're right, hamsters' faith in science has no boundaries. To be honest, I haven't even fired a single shot in my life, not even from a hunting rifle. However, back to business: it seems to me that the comments discussed the use of ceramics for armored vests, and not helmets? And the article itself does not talk about the use of "bricks" 200x200x50 for body armor.

[Riv]

So I did see these plates made of silicon carbide. 40x40x5 mm. He held in his hands. This thing is generally not a new invention. They tried to drill and saw them on our mechanical site - the diamond does not take (although they somehow managed to cut it). But with a blow, they crack very easily. With a strong impact, the energy will not even be split, but crushed to a state of coarse sand.
The bronic of them is most likely to hold a pistol bullet, but ... once.

When the syllable "nano" appears in the name, it immediately arouses strong suspicion. Because it usually boils down to either:
1. The misuse and illegal use of the term.
2. Quackery. Already inventing road nano-coatings.

Although here, it seems, we are talking about something real. Little information, unfortunately.

[Gormenghast]

I am not at all opposed to the fact that structuring increases strength; I just think it was someone outsider who put the term "nano" on the technology. It's like, "I figured out how to make the alloy stronger "to be accepted, I will call it" nano "... An outsider is: the project manager (who is a "co-author", but neither ear nor snout; a journalist who generally hovers in empyreanism; or, in general, according to general instructions - to call everything "nano").

[HAM]

I will believe in the remarkable properties of nanoceramics when it is tested on Chubais.

[Amurets]

That's right, in the old days, bridge builders stood under a new bridge to prove its reliability during the passage of a train. Everything that has been done at the Chubais department should be checked on Chubais and its associates.

[gridasov]

It would be understandable if they said that the distribution of the strongest magnetic force bonds is nanostructured according to spatial algorithms. And so it is clear that just "chaos".

[MAXUZZZ]

It has long been making ceramic armor with a techie like 6b43 for the army, protection class 6a, for civilians from high molecular weight polyethylene

[Vadim237]

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