Prediction of Flexural Fatigue Strength of CRFP Composites under Arbitrary Frequency, Stress Ratio and Temperature

Abstract

This paper deals with fatigue strength of a class of CFRP laminates satisfying certain hypotheses and proposes a prediction method of the fatigue strength at an arbitrary combination of frequency, stress ratio and temperature. Three-point bending tests were conducted for satin-woven CFRP laminates T400/3601 under static, creep and fatigue loadings. The experimental data support the prediction method and the hypotheses.
