摘要
The deformation and failure behavior of an aluminum matrix composite reinforced with short carbon fibers has been studied using acoustic emission (AE) techniques. At the onset of nonlinear deformation, plastic deformation of the matrix was noted in the AE r.m.s. signal, and the fiber fracture which occurred after plastic deformation of the matrix call be monitored with burst-type event signals. Fiber fracture observed at this stage could not be explained by the stress transfer mechanism. The fracture of fibers was strongly dependent on the shear slip of the matrix. Micromechanisms of the fracture process in the composite are discussed based on the AF results and the stress-strain response.
