Abstract
A face sheet is bonded to a porous core by contacting adhesive to the porous core at the bonding face, placing a screen stripping sheet overlying the adhesive, and pressing on the stripping sheet while heating the core and adhesive. The adhesive is thereby forced against the exposed portions of the cell walls at the bonding face and into the interstices of the stripping sheet. The excess adhesive not contacting the exposed cell walls is removed by cooling the stripping sheet and adhesive, and peeling the stripping sheet and excess adhesive from the core. A face sheet is bonded to the porous core with the remaining adhesive that adhered to the exposed cell walls.
