| 摘 要： | 孔隙是C/C复合材料结构中重要的组成部分,它直接影响着材料的疲劳行为,因此,在研究C/C复合材料的疲劳行为时,考察基体以及界面中孔隙的变化具有重要的意义.综述了C/C复合材料原始孔隙结构的特点,分析了在疲劳加载过程中碳/碳复合材料孔隙结构的演化规律,强调了孔隙结构变化对碳/碳复合材料疲劳强化所作出的积极贡献,进而为其疲劳机理的研究提供依据.

| Abstract: | Porous structure is an important component in carbon/carbon(C/C)composites,which directly af- fects the fatigue behavior of materials.Therefore,it is necessary to discuss the evolution of porous structure in C/C composites under the fatigue loading.In this paper,the character of porous structure in original C/C composites is sum- marized and the evolution of porous structure after fatigue loading is analyzed.The positive effect of the porous struc- ture evolution after fatigue loading on the reinforcing behavior of fatigue is proposed as well,which provids a basis for further studies on the fatigue mechanisms of C/C composites. |
