Russian Navy may adopt boats with a polymer hull

Boats "RIF-112" and "RIF-75"

The Russian Navy is considering adopting the RIF-122 series multifunction boats with a hull of high density polyethylene. Negotiations between the boat manufacturer and the Russian Navy are already underway. This was reported by TASS with reference to the General Director of the enterprise Gennady Vasilyuk.

According to the agency, the Navy is considering adopting boats of the RIF-122 series. As part of the Caspian flotilla since 2017, another model of the same manufacturer has been operated - the boat "RIF-75SK", which received good reviews. At the moment, negotiations are at the stage of forming technical specifications.

At the moment, negotiations are underway to supply a series of boats "RIF 122", which are distinguished by greater carrying capacity and passenger capacity compared to "RIF 75SK

- informed Vasilyuk.

According to him, the uniqueness of the proposed Navy boat lies in the material from which it is made - low-pressure polyethylene. This material is not subject to corrosion, does not require paintwork, can be used at ambient temperatures from minus 30 to plus 50 degrees. The life cycle of such a vessel is increased to 50 years. The boat of the "RIF 122" series can also be used in broken ice, which is confirmed by tests.

The multifunction boat "RIF-122" has a height of 3,7 m, a length of 12,2 m, a width of 3,5 m, a draft of 0,6 m, and a carrying capacity of 1,7 tons. The boat is capable of speeds up to 40 knots, the crew - 3 people + 9 landing men.

Probably the right thing. What will the Navy experts say?

I don’t know what the sailors will say, but for a fishing company, the thing is amazing if you live near a large body of water or a river.

I think they won't say anything yet, because the "animal" has not been tried.
Personally, I am confused by PND so that when it is minus, it becomes more prickly, although it is probably reinforced for such needs, + as in UV in combination with sea water?
PS.
I am sure that smart people know what they are doing.

[Antidote]

At -30, and so not really on a boat, without liquid water, and he does not care about sea salt. Here uh, yes it does.

I also thought about it))) what water at minus 30 but left it, it was recalled how he snapped his hand on the siding and burst)))

There is almost no specialist here, some whiners are left!
And on the topic, they will certainly receive landing craft .. The main thing is that they are not particularly expensive .. The Marines will understand!

And what is still hollowed out of logs?
Is fiberglass not a polymer?
They remembered polyethylene!
But is it just a binder? What is the basis? Fiberglass? Carbon fabric?

Is fiberglass not a polymer?

Fiberglass is not a polymer. It is a composite material of at least two different components.
Hulls are made of HDPE small, but 12 meters is already large for such a material. I don’t want to say “too much,” practice will show.

They remembered polyethylene!

Fiberglass is glass and plastic. With prolonged alternating loads, it delaminates. Yes, and heavy.
Polyethylene itself is more elastic, and less heavy. Only here about 50 years - I also have doubts. Unless closed storage ..
I have some plastic covers since the 70s of the last century. Not cracked, despite dozens of dips in boiling water before closing. Although clouded to black.

[Thrifty]

In all our messages about the adoption of technology into service, I "like" the word reading "maybe" !!!!!!

[knn54]

I am not a sailor, but for the minesweepers the polymer case is the most.

[cniza]

And for safe landing also does not hurt.

[Andrei Nikolaevich]

Oh! Fishing would be like that! What will the graduates of the Navy universities say? .. (about boats and not about fishing) -)

[Mountain shooter]

If reinforced, then it should be very good. But if cast? Here you have to watch. How is it in the cold? And how in the heat? Yes, under shock? Fire resistance? ...

[svan26]

Such cases are made either by molding in a matrix under heating or by welding HDPE sheets. There is no reinforcement. From the point of view of durability and unpretentiousness, the material is unique. Can be pulled ashore by stones. It does not have age-related delaminations like fiberglass, there are no electrochemical reactions like aluminum cases. Yes, in the cold, from -20 it becomes fragile, but water does not happen much below zero ...

No reinforcement

Most likely there is a power frame inside of steel or luminous profiles.

[svan26]

They make a set of the same PND. Sheets are cut on a stand by a robot and assembled for welding. Then sheathed with a sheet cut on the same stand. For the military, good technology. It withstands the direct hit of a fool behind the wheel. Rugged, shockproof and heavy body is obtained. But for the military, consumption is not fundamental ...

[Rzzz]

Yes, I saw a vidos. I saw in real life how they made hulls for a small catamaran, there was a steel frame inside, and then they hobbled the hulls.

[The Siberian barber]

I sincerely do not understand the essence of "news")
As if to this day, boats and wooden boats were. Or is it an advertising article?)

[Avior]

There were fiberglass, and this one is polyethylene

I read fluently, did not understand

Russian Navy may adopt boats with a polymer hull

The real answer to everyone who continues to shout frantically:

ναί παραλελοίπατε τά πολυμέρη

Perhaps further developments will improve the characteristics of the material, and beyond it and increase the tonnage of designed boats and even ships. See what cross-linked polyethylene has:

Tensile strength, which determines mechanical strength, ranges from 350 to 800% ... Very high level of flexibility ... Preservation of impact resistance at low temperatures to -50 ° C ... Service life under standard conditions - more than 50 years .

The production of ships for small rivers will also thank you ..
Forward! The road will be overcome by a walker

[da Vinci]

For this "innovation" will have to pay dearly, but is it necessary? It would be better to develop composites for aviation in 2-3 years in the direction of expanding the range and reducing the cost with excellent quality (at the level of world standards), increasing production volumes. The main thing is that the development of this direction should be paid for (of course with a profit for itself) by private business - it will not "cut" its own money, and the state will only be the customer. Then there will be new boats, and bodies for cars and much more.

[Oyo Sarkazmi]

Boeing 787 is made from Russian carbon fiber. BASF - the same quality, but 3 times more expensive. However, ours is at the price of gold.

[Berkut24]

If this boat were made in Ukraine, now the word "stealth" would be shouted across all ukrokanals ...

[From Siberia we]

And in Russia they would shout about the pelvis and our mighty fleet

[Berkut24]

The point is that in Russia a boat is just a boat. And in Ukraine it is a "battle ship" that will put the Russians in their place. So this is how a warship is a purely plastic tub.

[Flooding]

This material is not subject to corrosion, does not require paintwork, can be used at ambient temperature from minus 30 to plus 50 degrees.

Plus 50 Celsius is a lot, of course.
But under the direct rays of the hot southern sun, the material can heat up even more.
And what is the maintainability of such a case in case of damage?

It is sealed up. Rather, even brewed. And this is a plus, regarding fiberglass, which is being repaired much worse.
But the strength of fiberglass is higher.

[Whisper]

Some kind of small carrying capacity of 1.7 tons, with such dimensions of the case!

[lucul]

12.7 mm remote machine gun on the nose / roof and you can drive pirates in full.
For border guards, the very thing - as a workhorse.

[From Siberia we]

There are already "sable" and "mongoose"

[Dikson]

whose motors and which? Yes, even let them make recycled plastic waste .. - The demand for boats and boats in our country is always there and will be! There are enough reservoirs, seas and rivers ... And if the military makes an order, the enterprise will be able to fulfill orders for civil services and for individuals ..

[From Siberia we]

engines - america mercury

Quote: Dikson

Mercury or Volvo, if built-in. There are no others.
Hanging any is possible.
And if the water cannon - the choice of motors is also wider.

[svan26]

Yanmar and a whole bunch of Italians are stationary ...

[Rzzz]

This is all sorts of petty. Here the motor is needed in half a hundred horses, most likely gasoline (for compactness). Plus speakers, and this again is either Volvo or Merck.

[san4es]

... The company RIF JSC which is part of the Rostov Port group of companies builds boats from low-pressure polyethylene

[Amateur]

 Along with the positive properties, polyethylene has a number of disadvantages. It is flammable, susceptible to aging under the influence of sunlight, with prolonged exposure to loads, it irreversibly deforms, and cracks may appear.

And remember how some "innovator" back in Soviet times thought of fixing cartridges for light bulbs in chandeliers and table lamps with plastic nuts. They crumbled to dust in 2 - 3 years.
Or polyethylene san.pipes, lain a couple of years in the sun. At the slightest load they broke.

[From Siberia we]

Yes, for a long time the whole world rivets such boat boats. body type - RIB. 3 year cylinder warranty. really serve 6-7 years. and do not care, it's not freezing heat. then replace the cylinders.

[Dikson]

The Americans have had something like this since Vietnam ..

[From Siberia we]

The fleet has such boats - go fishing. And they will have a price - space.

[From Siberia we]

By the way, ships such as ship boats began to be delivered to ships. not bad, but the price is 18 lyam ......

[sagitch]

In case of an accident, if the crack bursts, the naskoryak cannot be repaired, only to the base.

[Avior]

If it bursts, it may not reach the base
