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.
