Abstract
Abstract The in-plain statistical acoustic emission radiation pattern analysis on fiber reinfected composite material is successfully developed. The method is based on both the analysis of the displacement field of Lamb wave and evaluation for the sensitivity of piezo-electric device properties. The sample of the test used is angle ply CFRP. The acoustic emission signal detected using special six piezo-electric resonant sensors developed in our laboratory. Signals from the sensors are acquired using two different systems, PAC 3000/3104 AE analyzer and Dynamic Crack Microscope, which is a six channel acoustic emission source characterization system developed in our laboratory. The fracture mechanisms of this sample consists of Mode I, which corresponds to the delamination, Mode II which corresponds to debonding, and Mode I and Mode II combined mode which corresponds to a continuous delamination.
