Abstract: Rather than spray coat face sheets of honeycomb panels with powder braze alloy or using foil strips of braze alloy between honeycomb core and face sheets, individual ribbon segments of brazing foil are positioned between successive honeycomb cell vertices or nodes. The arrangement is such that several such ribbon segments will lie essentially in parallel planes to each other and normal to the planes of the top and bottom panel sheets when these panel sheets are positioned to sandwich the honeycomb cells therebetween. Heat can then be applied to melt the ribbon segments resulting in a flow of the brazing material into the nodes as well as the contact line joints made between the top and bottom of the cell walls with the top and bottom panel sheets. Excess brazing material on the panel surfaces covering the open cell portions free of joints is thereby virtually eliminated and desirable ductility and elongation characteristics of the resulting structure are retained.
