Fatigue Behavior of Carbon Fiber Reinforced Epoxy Composites-(=45)4s Laminate Under Tension-Tension and Tension-Compression Fatigue Loading Test

摘要

Fatigue behaviors of carbon fiber reinforced epoxy laminated composite have been investigated. The (+45)4S laminates of T300/976 Carbon/Epoxy were utilized. The static tensile strength and tension-tension tension-compression fatigue loading tests at various levels of stress amplitude were measured. The median rank method was applied to predict the statistical proability of experimental data of fatigue life. The S-N curves for various survival probabilities were established using the pooled Weibull distribution function.
