摘要：

Edge notched A16061-T6 aluminum was repaired with a GFRP composite patch as a function of the number of stacking. Damage progress of specimen for tension load has been monitored by acoustic emission(AE). AE energy rate, hit rate, amplitude, waveform and 1st peak frequency distribution were analyzed. Fracture processes were classified into Al cracking, Fiber breakage, Resin cracking and Delamination. Displacement of a specimen can be divided into Region I, II and 111 according to acoustic emission characteristics. Region II where the patch itself was actually fractured was focused on to clarify the AE characteristics difference for the number of stacking.
