采用箔—纤维—箔方法制备了连续SiC纤维增强Ti3Al基复合材料（SiCf/Ti3Al），测定了两种SiC纤维增强Ti3Al基复合材料的力学性能，分析了热处理工艺对复合材料力学性能的影响，讨论了复合材料在不同条件下的断裂机制。研究表明，国产SiC纤维(无碳涂层)增强Ti3Al复合材料的界面结合强度高于有碳涂层纤维增强的复合材料，力学性能却低于SCS-6纤维(有碳涂层)增强的复合材料。当热处理时间延长时， SCS-6/Ti3Al复合材料界面反应层厚度增加，复合材料的力学性能下降。

The method of foil-fiber-foil(FFF) is adapted to fabricate the continuous SiC ifber reinforced Ti3Al composites(SiCf/Ti3Al), the mechanical properties of SiCf/Ti3Al are tested. Two kinds of SiC ifber reinforced Ti3Al composites are compared, and the inlfuence of heat treatment on the mechanical property is analyzed, the fracture mechanisms are discussed. It is noted that the interface force of ifber(without C coating made in china) reinforced Ti3Al composites is higher than that of SCS-6 ifber(with C coating) reinforced Ti3Al composites, the ultra strength of SCS-6/ Ti3Al is higher than that of domestic ifber reinforced Ti3Al composites. With increasing of heat treatment, the thickness of interfacial reactions of SCS-6/Ti3Al composites increases, the mechanical property drops.
