Summary:Title screen
The paper presents the results of the experimental study of damaging and fracture processes of fiber glass reinforced polymer (GFRP) samples, fabricated by vacuum and vacuum-autoclave molding. The specimens were tested under three-point bending at step-wise loading accompanied with in situ registration of acoustic emission (AE). Based on the results of AE data analysis, a method for estimating damage accumulation at employing various techniques for acoustic emission parameter treatment is proposed and tested. The results obtained at analyzing (i) power-law coefficient of total AE accumulation, (ii) b-value and amplitude density distribution and (iii) median frequencies are described and discussed. In doing so, estimation of bearing capacity of the PCM samples by the calculating power-law coefficient of the total AE accumulation is carried out. The amplitude distribution, the amplitude distribution density and the median frequencies of the AE signals are shown to clearly characterize particular stages of PCM sample damaging.
