Abstract
Notched fatigue behavior of woven fabric CFRP laminates at high temperature is examined, and an analytical model is applied to prediction of notched fatigue life at high temperature. Fatigue tests are performed at high temperature (100℃) on unnotched and center-holed coupon specimens of a plain woven CFRP laminate for different stress ratios. The experimental results show that tension-dominated and compression-dominated fatigue behaviors at high temperature turn insensitive to notch in a high cycle range, respectively, due to matrix cracking that occurs predominantly at the edges of a hole along loading direction. This feature is common to the tensile fatigue behavior at room temperature. By contrast, the compressive fatigue behavior remains notch sensitivity at room temperature partly because of a different damage mode of transverse cracking. Finally, a notched fatigue life prediction model is tested for the fatigue behavior at high temperature, and it is shown to be valid for the notched fatigue behavior of the woven fabric CFRP laminate at high temperature.
