Core-skin bonding is improved between honeycomb and composite face sheets
by applying a nylon-based (polyamide) adhesive to the edge of the
honeycomb prior to bonding. Edge coating of honeycomb with polyamide
adhesives is useful in further increasing the bond strength between
honeycomb and prepreg face sheets, especially when the matrix resin of
the prepreg is designed to adhere the prepreg to the honeycomb.
