使用一专门设计的模型制作了碳化硅（Ｎｉｃａｌｏｎ）／玻璃复合材料单纤维拉出试样。利用纤维拉曼峰波数偏移与纤维所受应变的近似线性关系，首先测定纤维热残余应变的分布，随后对伸出玻璃基体外的纤维段施加给定的拉伸应变，沿纤维轴向用拉曼光谱术逐点测定基体内外纤维的应变，最后依据力平衡原理将应变分布转换为界面剪切应力沿纤维轴向的分布。结果表明：在给出的实验参数下，界面传递应力长度为０．１８ｍｍ，最大界面剪切应力的位置在ｘ为０．１１ｍｍ处。
Using a specially designed model, a sample of Nicalon / glass monofilament drawn was drawn. Using the approximate linear relationship between the wave number shift of the fiber Raman peak and the strain of the fiber, the distribution of the thermal residual strain of the fiber is first measured, and then a given tensile strain is applied to the fiber length extending out of the glass substrate, Raman spectroscopy was used to measure the strain of fibers inside and outside the matrix by point. Finally, the strain distribution was transformed into the distribution of interfacial shear stress along the fiber axis according to the principle of force balance. The results show that under the given experimental parameters, the length of the interface transfer stress is 0.18mm, and the maximum interfacial shear stress is at x 0.11mm.
