Fatigue behavior of carbon fiber reinforced polyetheretherketone (PEEK) laminated composite [O/({+-}45){sub 4}/90]{sub S} was investigated. The [0/({+-}45){sub 4}/90]{sub S} AS-4/PEEK composite laminate under static loading and tension-tension fatigue loading tests were conducted at various levels of stress amplitude to study the effect of stress amplitude on the fatigue life. The experimental fatigue life data under different stress amplitude tests were estimated by median rank order-statistic cumulative-distribution function. Then, the fitting curves of estimated data were analyzed by utilizing the Weibull distribution function. The S-N curves for a series of cyclic loading at different survival probability were also presented and the damage behavior after fatigue loading test was also investigated by optical microscopy.
