Design and characterization of a multilayered hybrid cored-sandwich panel stiffened by thin-walled lattice structure

Low-density polyurethane (PU) foams have been commonly used for some structural purposes in marine applications. However, they have not been exploited as a structural core because of damage tolerance and durability concerns. The major drawbacks of sandwich panels having PU foam core are their poor mechanical properties and vulnerability to marine environmental conditions. Therefore, the present study aimed to contribute to enhancing both the...
