Abstract
A method of brazing the nodes of honeycomb core material and the top and bottom panels to the honeycomb core material to form a sandwich structure. The method comprises the insertion in selected cells of the core, a coil or loop formed of normally flat resilient braze foil ribbon under tension and then releasing the tension to allow the braze foil, coil or loop to be urged against the cell walls under its own resiliency. The top and bottom panels are then installed over the core adjacent to the cell faying edges to form top and bottom surfaces. Pressure is then applied from the panels toward the honeycomb core material. The temperature of the sandwich structure is then elevated until the braze foil is caused to melt. Capillary attraction causes the now liquid braze material to flow into the interstices between the cell nodes and between the faying edges of the honeycomb core cells and the adjacent panels.
