| 摘 要： | 采用复合材料界面微脱粘仪，根据纤维回推技术对ＳｉＣ纤维增强锂铝硅（ＬＡＳ）玻璃陶瓷基复合材料的纤维／基体界面粗糙度进行测试。结果表明该复合材料的界面粗糙度约８～１５ｎｍ。用ＴＥＭ，ＥＥＬＳ等手段，对界面的组成的形貌进行观察。分析和讨论了基体成分以及复合材料的热暴露对界面粗糙度的影响。发现Ｎｂ２Ｏ５在基体中的加入有助于减小界面粗糙度，而Ｂ２Ｏ３则使界面粗糙度上升。空气中热暴露使界面粗糙度急剧上升。

| Abstract: | The interfacial roughness of SiC fiber reinforced LAS glass-ceramics was measured by the push-out test. The fiber used in the test was partially pushed out from the surrounding matrix and subsequently pushed back in the opposite direction. In all cases,a rapid decrease in load occurred as the fiber was pushed back in its original position. TEM and EELS were used to study the interfacial composition and micro-morphology. It is suggested that matrix composition has substantial influence on interfacial roughness,be-cause different interfacial structures are formed by different matrix composition.The composite with Nb_2O_5 added in the matrix exhibits roughness smaller than that added with B_2O_3. In addition,the interfacial roughness of the composite exposed in high temperature in air was also studied. |
