Fatigue behavior of carbon fiber reinforced epoxy composites -[{+-}45]{sub 4s} laminate under tension-tension and tension - compression fatigue loading test
- National Tsing Hua Univ., Hsin-Chu (Taiwan, Province of China); and others
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 probability of experimental data of fatigue life. The S-N curves for various survival probabilities were established using the pooled Weibull distribution function. The theoretical prediction methods could be applied to illustrate the fatigue behavior of thermoset matrix polymer composites. Furthermore, the fatigue behaviors under tension - tension and tension-compression fatigue loading test were investigated. Both the stiffness degradation and the surface temperature change during fatigue test are discussed.
