【Abstract】 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.更多还原
