Abstract

Flexural fatigue behavior of a cross-ply laminated carbon/carbon composite had been studied. The results showed that fatigue behavior and residual strengths of the composite had a close relationship with the maximum applied stress level applied in the fatigue test. In the case of the stress level higher than the fatigue limit, specimens were serious delaminated after fatigue. In the fatigue limit stress level, different kinds of interfaces inside the composite were weakened after fatigue, and the residual flexural and interlaminar shear strength slightly increased and decreased, respectively. When the stress level was lower than the fatigue limit, only interfaces between carbon fibers inside one bundle were evidently weakened, and both of the residual flexural and residual interlaminar shear strengths were significantly improved.
