In this study the effect of moisture content on the fatigue behavior of the composite materials is investigated. Samples of random and woven fibers with polyester resin are used in this study. The samples are immersed in water for different period’s .The moisture content is measured .The results Showed that the moisture content has a significant effect on the fatigue life of the composite materials. The fatigue life decreases as the moisture content increase.
