The Influence of Dimension Effect on the Hydrothermal Aging Behavior of Aramid/Epoxy Composites

An investigation was carried out concerning the hydrothermal aging effect on water intake character of aramid/epoxy composites based dimension effect. The were manufactured by vacuum assisted resin infusion method (VARIM) kept in distilled and sea at 25 °C 70 for 6 weeks a controllable cabin. absorption behavior composite samples cut with different length/width (L/w) ratios assessed according to types temperatures. Besides, interpreted theoretically Fick model. experimental theoretical results showed that displayed tendency consistent Fickian Further, affected criteria such as water, temperature, L/w ratio. temperature increase caused more absorption. ratio both types.
