界面是复合材料极为重要的微结构,复合材料的综合力学性能很大程度上取决于纤维与基体之间的界面黏结性能。准确地评价纤维与基体间界面结合情况,进而对界面进行优化设计与调控,是制备高性能复合材料的关键之一,复合材料界面力学性能表征技术也因此备受关注。从微观和宏观两个方面详细阐述了纤维增强复合材料界面力学性能的表征方法,并分析对比了两类表征方法的优缺点,对开发新型复合材料界面力学性能表征方法及实验仪器具有重要的指导作用。
The interface between reinforcing fiber and resin is a layer of important microstructure of composites.The comprehensive mechanical properties of composites depend largely on the interfacial adhesion between fiber and matrix.It is one of the keys to accurately evaluate the interfacial bonding between fiber and matrix,and then optimize the interfacialproperties of composites.Therefore,the characterization technologies of interfacial properties of composites have also attracted extensive attention.All kinds of characterization methods of interfacial mechanical properties were introduced,and discussed their advantages and disadvantages.This review may had an important guiding role in the development of new characterization methods and test equipment for interfacial properties of composites.
