抄録

The fracture mechanisms in tensile loading of a fatigued chopped strand carbon fiber. reinforced thermoplastic (CFRP) are examined from the view points of AE count rate, amplitude distribution, and frequency analysis, and compared with those for a virgin specimen. SEM and SAM observations have also carried out. It is confirmed that the peak in the amplitude distribution of AE signals shifts to the higher value side with an increasing of the load and the characteristic relates to the degree of fatigue damage in the previous fatigue test. The phenomenon corresponds to debonding in the chopped tape layer, resin cracking and fiber breaking or pull out of the strand tape, and also recognized the reinforced effect with the strand tape and the fracture mechanisms.
