Researchers at the Institute of High Molecular Compounds of the Russian Academy of Sciences (IVS RAS) have created a new basalt composite material for fasteners designed for the needs of shipbuilding.
«We propose replacing the metal fasteners currently used in shipbuilding with fasteners made of lighter composite materials. We created a composition of polymers filled with basalt fiber. Fasteners made of such material are five times lighter than metal and much cheaper – a metal stud made of special grades of steel costs about 500 rubles, ours – less than 200 rubles»,
– said the Director of the IVS RAS Sergey Lyulin.
According to Lyulin, another important advantage of this fastener will be the absence of corrosion with constant exposure to moisture. In this case, the mechanical properties will be no worse than that of metal analogues. The composite proposed by russian chemists differs from foreign materials in the use of mineral fibers instead of carbon ones. This reduces the cost of production without affecting the strength of the fasteners.
At the moment, the first samples of such fasteners have already been produced. While scientists are comparing the characteristics of russian and foreign polymer raw materials for mass production.
«Preliminary studies show that our polymer is significantly better in performance, but slightly more expensive than its Western counterparts – however, it need to understand what will happen in mass production. Polymeric materials in Russian shipbuilding occupy a share of 0.6% of the materials used, although in other countries with developed shipbuilding this figure exceeds 20%.»,
— added by Sergey Lyulin.
The development of fasteners made of polymer and composite materials began at the IVS RAS, on the terms of reference of the Sredne-Nevsky Shipyard. According to the director of the institute, Sergey Lyulin, the center will develop and test samples of products from polymer, composite and hybrid materials for their use in the construction of ships at the enterprises of the United Shipbuilding Corporation (USC).
