Composites are today the most important component in many fields. If previously these materials were mainly used in space and aeronautical construction, today they are much more widespread.
Based on the above, the news that Russia has entered the top four in the field of composite production attracts special attention. This industry in our country is growing at 10% per year. In total, more than 150 projects with an investment volume of 160 billion rubles are being implemented on the territory of the Russian Federation.
The most striking example of the use of domestic composites is the Russian liner MS-21, which is 40% made of such materials. Do not forget about Su – 57, in which composites make up 25% of the total mass. We widely use multicomponent substances in the production of helicopters and drones.
However, these materials are not only used in the aircraft industry. For example, the most recent project 12700 Alexandrite mine defense vessel Lev Chernavin launched in the water is unique in that it is a vessel with the world’s largest monolithic fiberglass hull, formed by vacuum infusion.
Not without domestic composites and in the latest PD – 14 aircraft engine, which has already gone into series. These materials are used in the Ivolga 3.0 electric train, which recently entered the first route. Future plans to produce blades for wind turbines from composite materials are reported. However, that is certainly not all.
It should be noted that the above-mentioned achievements of Russia in the production of composites completely thwarted the plans of the United States and its allies to make the construction of our liner MS-21 impossible and, in general, to create serious problems for many sectors. of national industry. As a result, the sanctions imposed only accelerated the process of import substitution, which allowed the Russian Federation, as well as the United States, Japan and Western Europe, to enter in the top four in composite production.
Finally, we add that Soviet engineers developed the first domestic composite material in 1935 for the LaGG-3 fighter. We are talking about delta wood, created by pressing layers of birch veneer impregnated with special compounds.
