| Abstract: | As a new load carrying efficient material,foam core sandwich composite has gained more and more attention in aerospace,marine and energy fields.However,most sandwich composites have been limited to secondary structures,because the reliability has not been widely investigated.The water uptake,static and dynamic mechanical properties and fracture toughness after water immersion are reviewed.Finally,a water-proof method is proposed. |

| Keywords: | foam core sandwich water durability water uptake fracture toughness |
