| 摘 要： | 通过箔-纤维-箔法制备了SiC纤维增强TB8复合材料,采用光学电子显微镜(OM)、扫描电镜(SEM)和电子探针(EPMA)对复合材料的微观组织进行表征与分析,研究了真空热压复合时压力、温度和时间工艺参数对SiC纤维增强TB8复合材料微观组织的影响规律。结果表明:压力对复合材料基体与基体以及纤维与基体的结合有着显著影响,而温度对纤维与基体界面反应层影响较大。通过热压工艺的优化,可以有效控制界面反应层厚度,获得组织优良的SiC f/TB8复合材料。

| Abstract: | SiC fiber-reinforced TB8 composite was prepared by foil-fiber-foil method. The microstructure of composite was characterized by optical electron microscopy( OM),scanning electron microscopy( SEM) and electro probe microanalysis( EPMA),and the effect of pressure,temperature,time and other process parameters of vacuum hot pressing on the microstructure of SiC fiber-reinforced TB8 composite. The results show that pressure significantly affects the intermatrix bonding and the combination of matrix and SiC fiber. Temperature has a greater impact on the interface reaction between fiber and matrix. Through the optimization of process,the thickness of interface reaction layer can be effectively controlled,and the SiC fiber-reinforced TB8 composite with excellent microstructure can be obtained. |
