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.

      I think so far they will not say anything, because the "little animal" is not 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.

    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?

      Fiberglass is not a polymer. It is a composite material of at least two different components.
      Cases are made of HDPE small, but 12 meters - this is already large for such a material. I do not want to say "too much," practice will show.

      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.

      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 ...

          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 ...

    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

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

        The fact is that in Russia a boat is just a boat. And in Ukraine it’s a “warship” that will put the Russians in their place. So this is how a warship is a purely plastic pelvis.

    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.

          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.

    Along with the positive properties, polyethylene has several disadvantages. It is combustible, subject to aging under the influence of sunlight, with prolonged exposure to loads, it is irreversibly deformed, and cracks may appear.

    And remember how some kind of “rationalizer” even in Soviet times thought of fixing cartridges for electric lamps in chandeliers and in table lamps with polyethylene nuts. After 2 to 3 years, they crumbled to dust.
    Or polyethylene san.pipes, lain a couple of years in the sun. At the slightest load they broke.
