Research Progress of Continuous Fiber Reinforced Ceramic Matrix Composite in Hot Section Components of Aero engine

Abstract

Abstract Continuous fiber reinforced ceramic matrix composite (CFRC CMC) possessed low density, high temperature resistance, high strength and high toughness, which have been identified as a key and promising military material for replacing the traditional super alloy. CFRC CMC had been used in some hot section components, such as nozzle, combustor and turbine stator on M88-2, F100-PW-229, CFM56-5B, F-135, GEnx, LEAP-X and other aeroengines. Manufacturing technologies of CFRC CMC were thought as the commanding elevation for hot section components of aeroengines, and therefore much attention was given in Europe, America, Russia and other developed countries and regions. The evaluation and application of CFRC CMC were introduced in detail. Further, the challenge and tendency in the future were also put forward in this study.
