提出了一种测量金属基复合材料（MMC）界面摩擦剪切强度的压痕法。利用西安交通大学研制的微压头对单根纤维的末端施加压力，使其压入基体中。MMC的力和纤维位移之间的关系线性变化，直到平台到达，在那里发生滑动力Fs。在此基础上，得到界面摩擦剪切强度τf的表达式为τf= Fs / 2πRt，其中R和t分别为单纤维半径和试件厚度。
The indentation method for measuring the interfacial frictional shear strength in a series of metal matrix composites(MMC)is presented. A microindenter, made by Xian Jiaotong Univerity, is used to apply a force to the end of the single fiber and depress it below the matrix. The relation between the forces and the fiber displacements of MMC varies linearly until a platform reaches, where the sliding force Fs occurs. Then, the interfacial frictional shear strength τf is expressed as τf= Fs / 2πRt, where R and t are radius of single fiber and the thickness of specimen respectively.
