Russia begins production of lightweight, non-magnetic composite shafts for ships
Russia has begun serial production of carbon fiber composite shafts for ships that are three times lighter than metal, non-magnetic, and reduce noise.
Russia has launched serial production of carbon fiber composite shafts for ships, the chief designer of the Perm Machine-Building Plant announced.
Aleksey Zaharov, the plant's chief designer, stated that these shafts are suitable for all types of displacement vessels and boats.
Lightweight and Non-Magnetic
Zaharov noted that composite ship shafts had not been produced in Russia before. The newly developed composite shaft is three times lighter than conventional metal shafts, he said.
A metal shaft weighs about one ton, while the carbon fiber composite shaft weighs only 300 kilograms, he explained.
The shaft also reduces the vessel's noise and is non-magnetic.
Import Substitution
The chief designer said that such shafts were previously purchased from Europe, particularly from the German companies Centa and Vulcan.
He stated that this supply was cut off after 2022 and the products began to be sourced from Asian countries.
Metal shafts are produced by forging, are heavy, and require significant labor in manufacturing, he added.
Zaharov said, "This is our Russian import substitution product. Now, if we become competitive in terms of price and quality, we will supply everything ourselves. We can make them in any length and diameter, for any type of displacement vessel or boat."
The metal-composite ship shaft, designated VMK-60-1, is designed to transmit rotation from the main engine to the propeller.
It was exhibited for the first time at the "Fleet-2026" maritime fair held in Kronstadt in June.
