Tension-Compression fatigue behavior of carbon fiber reinforced epoxy composites subjected to low energy impact was investigated. The [0/45/90/-45]2S laminates of T300/976 Carbon/Epoxy were utilized. The impact toughness and residual strength after various low impact energies were measured. The static tensile strength and tension-compression fatigue tests at various levels of stress amplitude were also measured. The median rank method was applied to predict the statistical probability of fatigue fife and residual strength after impact. The S-N curves for various survival probabilities were established using the pooled Weibull distribution function. The theoretical prediction methods were applied to illustrate the fatigue behavior of thermoset T300/976 Carbon/Epoxy [0/45190/-45]2s laminated composites.
