Abstract: The patterns of the amplitude distributions of the acoustic emission for various kinds of GFRP are determined to imitate some fundamental failure moles such as matrix crazing,fibex-matrix interface failure,delamination and fiber breakage.Two kinds of laminates are made of glass-weave/resin and glass-fiber/resin prepregtapes.Various kinds of stacking sequences,including 0°,±45°,0°/90°,are selected.The amplitude distributions of the acoustic emission are monitored at various loading stage.The amplitude distributions of the resin specimens with different glass fiber bunches are also investigated.
