Résumé

The purpose of this work is to use acoustic emission signal parameters to identify and characterize the various damage mechanisms in composite and composite-antenna-structures during tensile and buckling loading. The wave form, FFT diagram, peak power, frequency centroid, peak frequency, absolute energy, average frequency, duration and amplitude were used for discriminate the acoustic emission signals, enabling a correlation with the damage mechanisms modes: fibre breakage, interfacial debonding fibre/matrix, micro and macro matrix cracking, delamination onset (microdelamination) and propagation of delamination (macrodelamination). These results open perspectives for real-time damage monitoring in complex composite material.
