| 摘 要： | 对于ＳｉＣ纤维／ＭＡＳ微晶玻璃复合系统，发现在烧结温度下，纤维和基体之间有较严重的化学反应发生，界面结合强，力学性能较差．通过对ＮｉｃａｌｏｎＳｉＣ纤维加涂层，发现Ｎｂ２Ｏ５和ｃ涂层对复合材料的界面结合改善不大，而ＬＣＡＳ晶玻璃涂层能使纤维和基体间的界面结合明显减弱，力学性能大幅度提高，室温抗折强度和断裂韧性分别达３２７ＭＰａ和１３．９ＭＰａ·ｍ１／２．

| Abstract: | In SiC fibre/MAS glass-ceramic composite, there is a chemical reaction between SiC fibre and MAS glass-ceramic matrix. The interfacial bonding is very strong and thg mechanical properties of composite are low. Through coating SiC fibre with Nb2O5, C and LCAS glass-ceramic respectively, the Nb2O5 and C coating improves interfacial bonding little. The LCAS glass-ceramic coating weakens the interfacial bonding and the composite shows high mechanical properties. The fie-cural strength and fracture toughness of SiC fibre/LCAS glass-ceramic costing/MAS glass-ceramic composite are 327MPa and 13.9PMam1/2respectively. |
