Abstract
Abstract This study aims to investigate the hydrothermal effect on the buckling behavior of glass/aramid/epoxy hybrid composites under distilled and seawater environments. The four types of composite groups ([G 6 ] S , [A 6 ] S , [G 3 A 3 ] S , [A 3 G 3 ] S ) produced by vacuum infusion method were immersed in distilled and seawater at 25 and 70°C for 1000 h. The buckling test was carried out for dry, wet, and redried conditions. The periodic measurements showed that as temperature increases, the maximum water gain ratios also increase for all composite groups. Furthermore, the water absorption parameters were affected by the type of fluids. The buckling test results showed that both temperature and fluid type are effective on the critical buckling load of specimens. The increase in the critical buckling load of the hybrid samples tested in the redried state was less than the samples tested in the wet state for both temperatures. Moreover, the critical buckling loads of the composites aged in seawater were higher than the composites aged in distilled water.
