摘要

摘要: 针对细编穿刺C/C 复合材料中单丝/碳基体和纤维束/碳基体不同层次界面结构特性, 分别设计、建立了表征这两个层次界面结合性能的原位顶出仪, 并将界面结合性能与C/C 复合材料层间剪切强度测试进行了比较。利用该原位技术, 研究了不同工艺参数条件下C/C 复合材料这两个层次界面结合性能的关系, 并讨论了它们对C/C 复合材料拉伸强度的影响。表明: 本文中所建立的单纤维和整束纤维顶出技术可用于定量表征C/C 复合材料的不同层次界面粘合性能。不同层次界面结合状态在一定程度上对材料宏观力学性能的影响是不同的。

Abstract: To study the different graded interfacial characteristics of fiber/matrix and fiber bundle/matrix for carbon/carbon composites, two sets of push ouTinstruments for evaluating the interfacial bonding properties were designed and established respectively. Meanwhile, by using the push out techniques, the relationship between the bonding strength of these two graded interfaces under different processing parameters of C/C composites was investigated and their effects on the tensile properties of C/C composites were discussed. ITis found that the fiber and fiber bundle push out test techniques established in this paper can be used to evaluate the different graded interfacial bonding properties of C/C composites quantitatively. The results reveal that the different graded interfacial bonding status provides different contributions to the macro mechanical properties of C/C composites to some extent.
