纤维树脂基复合材料微观界面性能表征方法的进展

A Review of Methods for Characterisation of Interfacial Properties of Fiber Reinforced Polymer Composite Materials

纤维树脂基复合材料中界面微观结构和性质对材料的宏观性能起着关键性作用。为了能够准确地测试纤维树脂间的界面粘结力,表征纤维与树脂之间界面剪切应力传递效率,人们一直试图找到一种方法能够真实全面反映界面性能,以及纤维断裂、界面脱粘、树脂横向断裂等因素对界面性能的影响。为此作者对现有微观界面表征方法进行介绍与分析,包括:微珠试验、单纤维拉出试验、压入试验、单纤维断裂试验、激光拉曼(或荧光)色谱法、光弹分析法,全面剖析它们的适用范围。

The property of a fiber composite depends crucially upon the interfacial micro-structure and properties between the fiber and polymer matrix. To accurately characterize the interfacial adhesion, and interfacial shear stress transfer efficiency. Many attempts were dedicated to find a method to clarify the interfacial properties, and the effects of the fiber break, the interfacial debonding and matrix crack on the interfacial properties. Here the authors introduced and analyzed current approaches, and tried to find their limits.
