摘　　要：界面在纤维增强复合材料中具有特别重要的作用,它不但是纤维增强复合材料中增强相和基体相连接的纽带,也是应力及其他信息传递的桥梁。良好的界面粘结才能使纤维的性能得到充分发挥,进而纤维增强复合材料的力学性能得到提高,因此对纤维增强复合材料的界面粘结性能、界面微观结构的研究非常重要。本文总结了纤维增强复合材料界面剪切强度、界面微观结构的表征方法,包括单纤维拔出试验、纤维断裂试验、纤维压出试验等,并侧重介绍了拉曼光谱对纤维增强复合材料界面粘结性能、界面微观结构的研究。The interface has a particularly important role in fiber-reinforced composite material. It is not only a link between the reinforced phase and the matrix phase, but also a transfer bridge of stress and other information. Good interfacial adhesion makes the properties of fibers into full play, and improves mechanical properties of fiber-reinforced composite materials. It＇s important to assess interface adhesion and interface microstructure of fiber reinforced composites. The paper summarizes characterizing methods of the interfacial shear strength in fiber reinforced composites, including single fiber pulling-out test, fiber fragmentation and fiber pushing-in test and etc. In addition, the paper particularly emphasizes on characterization of the interracial adhesion and microstructure in fiber reinforced composites by using Raman spectrum.
