【Abstract】 Due to low density, high strength, high temperature resistance and other excellent properties, fiber reinforced ceramic matrix composites are the world’s cutting-edge materials currently used in the aerospace field. Pores, being common defects in the materials, have significant impacts on various mechanical properties of the materials, and will further affect their safety and life during the service stage. In this paper, the generation of pores and detection methods are firstly introduced. Then the theoretical, numerical simulation and experimental research progress of pores are presented; finally, the overall research trends of the influence of pores on fiber reinforced ceramic matrix composites are discussed and prospected.更多还原
