A honeycomb sandwich panel modified by the controlled incursion of a foaming fiber-filled adhesive into the upper region of the honeycomb provides a panel having increased durability when the upper surface is subjected to localized compressive loads.
A modified honeycomb sandwich panel having upper surface enhancement for improved resistance to localized compressive loads which comprises a honeycomb core sheet having a multiplicity of cells, said cells directed traverse to said panel; a bottom skin adhered to the lower surface of the honeycomb with an adhesive; and a top skin adhered to the upper surface of the honeycomb core sheet with a foaming adhesive which partially penetrates into the upper region of the honeycomb core as the adhesive cures thus increasing the density of said core in said regio...
