Abstract
The use of a simple acoustic emission (AE) technique to study the failure process in carbon-glass hybrid composites is studied. The technique incorporates an unconventional frequency spectrum analysis procedure. The frequency spectrum of AE signals was recorded during the tensile testing of composite specimens. It is found that, in the case of glass-epoxy composites, the high frequency components begin to appear at earlier stages in the load cycle compared to those observed in carbon-epoxy composites
