Russian composite shipbuilding innovation record

According to Russian media news, Russian experts poured the world’s largest ship for the first time at the St. Petersburg Shipbuilding Plant, and the hull of the ship was made entirely of composite materials. Its height is 8 meters. Discharge is almost 2 tons.

According to the order of the Russian Navy's new torpedo boat, the Sledny Nevsky Shipyard constructed the ultra-modern ship, which is completely made of carbon-plastic material. From all indicators, this torpedo ship surpasses all existing ships of the same type. In an interview with Voice of Russia, the general manager of the shipyard, Vladimir Sheridoho, said: “We have been working on the construction of glass plastic hulls for more than 40 years in the shipyard. The first ship of this kind It was launched in 1963 and is also used for demining purposes. Now, our new design is completely using new process technology. The use of the most advanced materials, such as glass cloth, carbon cloth. The production process has also changed, we have mastered Non-contact vacuum injection method".

The uniqueness of this new process is that, at the beginning, special materials are used to form the shell of the hull, and then they are soaked and filled with special materials through pressure without anyone's participation. The entire production process is monitored by computers. After that, the composite began to solidify. In terms of strength, the hull is not inferior to a ship made of steel, but its weight has changed from the normal 200 tons to 70 tons. Vladimir Sheredotho emphasized: “The new technology is characterized by the combination of new material processes and computing programs, and we have found a way to fully automate the entire process. In other countries, we can only accomplish In part, we have combined all of our processes organically to enable them to be effectively controlled. In addition, we are now able to build hulls up to 8 meters in height, but we could not exceed 5 meters in the past. This technical difficulty we succeeded But in other countries it has not yet reached this level."

The Navy uses this composite ship primarily for demining and maritime guards. Its main advantage lies in its concealment, because this composite radar is undetectable. In addition, the hull does not rust. The sudden drop in weight also greatly reduces the amount of fuel used.

In addition, according to the general manager Vladimir Sheredhoho, the production of ships from composite materials is a dual-use technology. This technology can also be used in the production of civilian speedboats, sailing boats and passenger ferries.

The achievements of St. Petersburg's designers and shipbuilding experts can not only enter the Guinness Book of Records, but also be introduced by numerous international publications, because it is indeed a product of the era and the development of ships. A new stage.
