Experimental Investigation of Low Velocity Impact and Residual Compressive Properties of Composite Laminates Based on AE

Abstract:

The low-velocity impact and residual compressive failure processes of composite laminate were investigated by the acoustic emission (AE) technique in this paper. The AE energy, amplitude, and the peak frequency were analyzed. At the same time, combining with the load-displacement curve varying feature, the compressive fracture processes were divided into different stages to deeply understand the damaged mechanisms of the composites. Results reveal that the behavior of AE parameters described well the fracture process of the composites.
