- Characterization of Fatigue Damage Behavior in Unidirectional Carbon Fiber Reinforced Plastic Laminates
抄録
<p>In this study, interim stopping tensile fatigue tests with acoustic emission (AE) measurement were performed on unidirectional carbon fiber reinforced plastic (CFRP) laminates with a notch. The relationship between splitting behavior and associated AE behavior were characterized. Then, tensile fatigue tests with AE measurement were carried out on CFRP laminates without a notch, and the damage and AE behaviors with and without a notch were compared. Consequently, splitting occurred along the fiber direction from the tip of a notch in a specimen with a notch and the AE behavior reflected the splitting developing behavior. We discussed the AE behavior based on the experimental results about splitting behavior, and the relationship between the AE and the fatigue damage behaviors in unidirectional CFRP laminate was clarified. From this relationship, it is possible to predict the damage type by comprehensively evaluating the frequency characteristics and each parameter of AE waves. The AE waves from splitting occurrence and progress were also identified.</p>
