  • Method and tooling arrangement for diffusing braze weight pressure in brazing of aerostructure honeycomb sandwich panel
    Patent number: 6199742
    Abstract: A method of brazing together a lightweight metallic aerostructure sandwich panel having at least two spaced face sheets and an intermediate honeycomb core layer comprises: providing a tooling base having a determinable upper surface; assembling spaced upper and lower metal face sheets and an intermediate metal honeycomb core layer together with at least one layer of braze material upon the upper surface of the tooling base to provide an unbrazed aerostructure panel; positioning a layer of conformable working honeycomb core upon the upper face sheet; positioning apressure means upon the layer of conformable working honeycomb core to provide downward pressure upon the layer of conformable working honeycomb core and causing the conformable working honeycomb core to provide a uniform downward pressure over the upper face sheet of the unbrazed aerostructure panel; and subjecting the unbrazed aerostructure panel to a predetermined cycle of elevated temperature and time to permit the layer of braze material to
