主要介绍了近年来国内外C/C复合材料疲劳性能的研究进展,并根据疲劳载荷类型系统地总结了C/C复合材料疲劳性能的主要研究方法,归纳出C/C复合材料疲劳损伤的主要特点,即多种损伤形式、高的疲劳极限、剩余强度增加以及实验测试数据分散性大。在此基础上,提出了进一步研究C/C复合材料的疲劳性能值得关注的课题。
The research progress at home and abroad in recent years on fatigue properties of C/C composites is introduced. The main research methods for fatigue properties of C/C composites are systematically reviewed according to the loading types, and characteristics of fatigue damage of C/C composites are concluded, including fatigue damage with different forms, higer fatigue limit than metal or isotropy material, residual strength larger than sample un-fatigued, and biger distration of the data for the experimental result. On the basis of the present research progress, the further popular projects are also suggested.
