Abstract: Silica fiber reinforced silica ceramic composites have excellent mechanical, dielectric, ablation and thermophysical properties, and are the preferred materials for high-speed missile radomes and antenna windows. In this paper, the research progress of silica fiber reinforced silica ceramic composites at home and abroad is summarized from the aspects of their preparation methods, the silica fabric structures and the pretreatment technology, the cyclic impregnation and the post-treatment technology, the moisture-proof treatment of composites and the development of composite materials; the directions of their future development are also analyzed.
Key words: silica fiber; silica fiber reinforced silica; SiO2f/SiO2; ceramic composites
