Abstract: Compared with traditional metal material, Al2O3 fiber reinforced Al2O3 matrix (Al2O3/Al2O3) composites have become a new generation of thermos-structured composites for aerospace that have attracted much attention from scholars all over the world due to their high specific strength, low density, high temperature resistance and oxidation resistance. This paper introduces the commonly used Al2O3 fibers and their basic properties, summarizes the frequently used interfacial phases in Al2O3/Al2O3 composites and their influence on performance of composites, summarizes the preparation process of Al2O3/Al2O3 composites and their properties, and points out the future development trend of this material, aiming to provide a reference for the research of Al2O3/Al2O3 composites in China and promote the widespread application of Al2O3/Al2O3 composites in high-temperature components at the hot side of aerospace industry.

Key words: Al2O3, composite, fiber, interfacial phase, manufacturing process
