文摘	国外在航空发动机用SiC_f/SiC复合材料的研发和应用方面进展迅速,这得益于其开展了大量的材料级性能测试并借此建立的材料性能数据库。本文梳理了SNECMA,NASA,GE公司典型SiC_f/SiC复合材料牌号的基本物理性能和力学性能,探讨了制备工艺等因素对材料性能的影响,着重分析并讨论了复合材料的拉伸性能;同时综述了国外在该类材料使用性能方面开展的测试,主要包括高温抗氧化性、高温水/氧环境性能、疲劳及蠕变性能、抗热冲击性能以及抗外来物冲击测试等,并对材料在热、力、水、氧等不同环境因素下的损伤行为和失效机制进行了阐述。在此基础上,提出了我国在SiC_f/SiC复合材料后续性能测试研究方面的建议。
其他语种文摘	The research of SiC_f/SiC ceramic matrix composites(CMCs)as well as their applications in aero engines has obtained rapid development recently.This is owing to the large quantity of coupon tests performed on various properties of these materials,and the establishment of corresponding databases. Here,the physical and mechanical properties of CMCs developed by SNECMA,NASA and GE were reviewed.The influence of fabrication techniques on the properties of materials were discussed with an emphasis on tensile properties.Meanwhile,the service performances of these materials were summarized,including oxidation,water vapor/oxygen environmental resistance at high temperature, fatigue and creep behaviors,resistance to thermal shock and foreign object damage,along with the mechanism of damage and failure in environments such as heating,loading,water and oxidation.At last,some suggestions about domestic further research on performances testing for SiC_f/SiC ceramic matrix composites were proposed.
