Abstract

The article presents the results of the work over the past 10 years on the development of materials for use in the design of the engine nacelle of the power plant of a helicopter made of PCM. As part of import substitution, the issue of replacing the carbon reinforcing filler with a nominal surface density of 200 g/m2 of the Porcher brand (made in France) with a local analogue is considered. Domestic carbon fillers based on carbon fibers produced in China and the Russian Federation are studied. Studies of carbon fiber on the selected fabric are conducted based on the results of comparative tests. The material is shown to meet the specified requirements of the developer. The results confirm possible prospect of using the new carbon fiber in promising helicopters such as the Mi-171A3, Mi-38 or Ansat.
