The heart-skin bond between the honeycomb structure and the composite face sheet is improved by applying a polyamide and / or rubber containing adhesive to the edges of the honeycomb structure and then bonding. Coating the edges of the honeycomb structure with a polyamide and / or rubber-containing adhesive is useful for further increasing the bond strength between the honeycomb structure and the prepreg face sheet, and in particular, the matrix resin of the prepreg. Is useful when designed to adhere a prepreg to a honeycomb structure without the use of a separate structural adhesive. |
