The Effect of Seawater on Buckling Behavior of Natural Fiber Reinforced Composites

In this study, the critical buckling loads of natural fiber reinforced glass fiber composite specimens with different stacking sequences kept in seawater were experimentally investigated. Jute and glass fabrics as fiber and epoxy resin as matrix were used to produce the composites in different configurations. Alkali treatment was applied to jute fabrics in order to increase the amount of adhesion between the reinforcement and the matrix. Composite specimens were subjected to buckling test kept in seawater and room conditions for two months (60 days). Critical buckling loads of natural fiber reinforced composite specimens were determined in the direction of the data obtained as a result of the tests. As a result of the experimental study, it was seen that sea water influenced the buckling strength of natural composites in the negative direction. When the symmetric and antisymmetric composites were compared, it was observed that the critical buckling stress in the specimens with antisymmetric (02g/902j)us kept in Mediterraneanseawater was lower than those with symmetric sequence(02g/902j)s
