A MEASURE OF THE INTERFACIAL SHEAR STRENGTH BETWEEN THE FIBER AND THE POLYMER MATRIX BY ACCOUSTIC EMISSION
聚合物基复合材料界面剪切强度的测试

This paper describes the application of an acoustic emission(AE)techniquefor locating the positions of fiber breaks,and thus determing the length distribution of thefiber fragments resulting when a composite specimen containing a single fiber is loaded tofailure.Using a micromechanical model,it is possible to determine a measure of theinterfacial shear strength between the fiber and the matrix from the fragmentation lengths.The acoustic measurements can be used with fibers embedded in a non-transparent matrixsuch as metal and ceramic matrix materials.
