Application of polyimide in aircraft engine
In recent years, high-performance aero-engine technology has developed rapidly. In order to further improve the performance of aero-engines, more and more resin-based composite materials are used to replace metal materials in aero-engines in order to achieve the purpose of lightweight. Among them, polyimide resin-based composite materials Because of its excellent heat resistance, it is widely used in aero engines and aircraft
Foreign research on polyimide composite bushings for aero-engines began in the late 1960s. After more than 40 years of research and development, polyimide composite bushings have formed a variety of material systems, mainly including graphite filling Composite Material bushing, fiber braided composite material bushing, chopped fiber composite material bushing and other types.
