| Abstract: | Polymer-derived method is the main preparation method for continuous SiC fiber. So far, three generations of SiC-based fibers have been developed. SiC fiber is mainly used as reinforcement for SiC matrix to prepare SiCf/SiC composite, which exhibits excellent properties such as high-temperature resistance, oxidation resistance, high-temperature creep resistance, and neutron radiation stability. Therefore, it is considered as a promising preferred alternative material for structural components which works under harsh environments. In this review, the domestic and oversea development of the polymer-derived SiC fibers are introduced, in particular the different approaches for preparation and the characteristics of the 3rd generation fibers. Then, the development of SiCf/SiC preparation technology and properties are reviewed and the relationship between the innovation in fabrication of SiCf/SiC composite and the development of SiC fiber is hightlighted. Finally, the application progress of SiCf/SiC composite in high performance aero-engines and fusion power cores is summerized. Meanwhile, some perspectives on the development of domestic SiC fibers and SiCf/SiC are also discussed. |
