Application and development of advanced composite materials in foreign aeroengines

The application of advanced composite materials in aeroengines has become one of the key technologies for improving engine performance, reducing mass and enhancing fuel efficiency. This article reviews the current status and development of advanced composite materials in foreign aero-turbofan engines, with a focus on the application of polymer composite PMC materials such as epoxy resin and polyimide, metal matrix composite MMC materials such as titanium alloy and aluminum alloy, and ceramic matrix composite (CMC) such as silicon carbide and aluminum oxide in engine components such as fan casings, low-pressure compressors, high-pressure compressors, high-pressure turbines, low-pressure turbines and nozzles. By analyzing the application and research and development progress of foreign aircraft engines in matrix, metal matrix and ceramic matrix composite, this paper explores their advantages in improving thrust to mass ratio and temperature resistance performance. At the same time, this article also looks forward to the future development direction of various composite materials in aeroengines, including the research and development of new composite materials, optimization of manufacturing processes, and potential applications and development trends of various composite materials in future aeroengines.
