Abstract :In the present study, the effects of hot water ageing on the glass fiber reinforced epoxy woven composites were experimentally examined. The specimens in three groups which  undamaged, damaged, and single patch-repaired ones were kept in tap water at 50°C and 70°C temperature for 8 days and 16 days. At the end of those periods, the moisture absorption rates were calculated, the maximum failure loads at the end of period of keeping in hot water were determined and the failure modes occurring on these specimens were observed and compared. As a result of experimental study, it was found that the moisture absorption rates increased but the failure load values decreased together with the increase in water temperature and duration of hot water ageing.
