单纤维拔出测试的结果反映了粘结剂、粘结剂和摩擦现象的组合，这些现象使微观机械建模和与复合材料性能的关系复杂化。断裂表面的扫描电子显微镜图像检测到，在从延性和脆性基质中拔出尺寸适中的纤维的过程中，粘结断裂和不稳定的裂纹扩展。新的非破坏性方法已经被用来表征中间相的物理性质。原子力显微镜在力调制模式下可以可视化1到3微米厚度的中间相和取决于纤维基质模型复合材料的梯度。单纤维动态载荷试验已被证明是一种可行的工具，用于确定纤维与基质的粘附力或摩擦力以及基质的延性。(C)1998由爱思唯尔科学有限公司出版。版权所有。
Results of single-fibre pull-out tests reflect a combination of adhesive, cohesive and frictional phenomena that complicate micromechanical modelling and the relation to composite properties. SEM images of fracture surfaces detected cohesive fracture and unstable crack propagation during pull-out of well sized fibres out of both ductile and brittle matrices. New non-destructive methods have been used to characterize the physical properties of interphases. Atomic force microscopy in force modulation mode has visualized interphases of 1 to 3 mu m thickness and gradients depending on the fibre-matrix model composite. The single fibre dynamic load test has been shown to be a feasible tool for determination of fibre-matrix adhesion or friction and ductility of matrix. (C) 1998 Published by Elsevier Science Ltd.
