The low-velocity impact and compressive failure processes of composite laminate were investigatedby the acoustic emission ( AE) technique in this paper． The test procedure was monitored by the acoustic emission( AE) technique． Combined with load-displacement curve during testing，the AE energy，amplitude and the peak frequency of a dominant frequency band after treated with the fast Fourier transform( FFT) were analyzed． The fre-quency spectrums of the waveforms for the type signals were discussed． Ｒesults reveal that the behavior of AE pa-rameters described well the damage process on the low-velocity impact and residual compressive behaviors of thecomposite laminates．
