- Effect of Carbon Fiber Type on Splitting Growth Behavior in Unidirectional Carbon Fiber Reinforced Plastic Laminates
抄録
<p>To evaluate the fatigue damage behavior of a unidirectional carbon fiber reinforced plastic (CFRP) laminates, interim stopping tensile fatigue tests with acoustic emission (AE) measurements were performed on specimen with a notch. The relationships between damage behavior and AE behavior were characterized. From the results, splitting occurred from a notch and rapidly progressed for all specimens. Also, the relationship between the obtained damage behavior and AE behavior suggests that damage can be identified by comprehensively evaluating the frequency band of the AE wave and each AE parameter. We also compared the results of each CFRP laminate and investigated the effects of carbon fiber types on splitting growth behavior and AE behavior. The length of splitting at the cycle limit value and the splitting growth rate tended to be different for each CFRP laminates. We considered that splitting growth behavior was affected by the stiffness of CFRP laminates, stress condition and interfacial strength between fiber and matrix.</p>
