Abstract: SiCf/SiC composite materials exhibit characteristics such as lightweight, low density, excellent high-temperature stability, superior mechanical properties, outstanding chemical stability, and high wear resistance, making them ideal for hot-section components in aero-engines. This paper primarily introduces the current development status of SiC fibers, the fabrication processes and properties of SiCf/SiC composites, and the application progress of SiCf/SiC composites in aero-engines. It further analyzes the challenges currently faced in the development of SiCf/SiC composites and proposes key priorities for their future advancement.

Key words: SiCf/SiC composite materials, SiC fibers, preparation techniques, application in aero-engines
