摘要
连续SiC纤维增强SiC陶瓷基复合材料(SiCf/SiC)具有良好的高温力学性能、抗氧化性及放射耐受性等,是继Cf/C和Cf/SiC复合材料之后航空航天和原子能等领域最理想的新一代高温结构材料。从原材料、制备技术、微观结构与性能及应用等方面对SiCf/SiC复合材料的最新研究进展进行了综述,并对其发展趋势进行了展望。开发新型制备技术和优化现有技术及采用其联合工艺减低成本,进一步优化材料微观结构提高其使用性能是今后SiCf/SiC复合材料的研究重点。
Silicon carbide （SIC） continuous fiber-reinforced SiC ceramic matrix composites are attractive for their excellent mechanical properties and oxidation resistance at high temperature and an inherently low induced-activation energy. They are the most promising high-temperature structural materials for aircraft and fusion energy applications and so on later after Cf/C and Cf/SiC composites. In this paper, a brief introduction is given to the common SiC fibers, The research status of SiCk/SiC is reviewed with respect to fabrication techniques, microstructures, properties and applications, The prospect of the composites is expected. The main aspects of the future researches on SiCk/SiC composites are to develop new fabrication techniques and optimize and unite the merits of present fabrication techniques to low the cost of the composites, and to optimize the microstructure for improving the properties of the composites
