Abstract
A core structure, apparatus, and method which utilize laser bonding to fabricate the core structure. The core structure is characterized by laser bonds in patterns between adjacent sheets of aluminum, stainless steel, and titanium foil which create honeycomb core structures when the bonded stack of sheets is expanded by the application of tensional forces thereto. The apparatus achieves the fabrication of the core structure and the steps of the method are practised by either hand or utilization of the apparatus.
