ABSTRACT:
A composite titanium or titanium alloy structure is made by diffusion bonding upper and lower face sheet components onto opposite sides of a honeycomb core component at an elevated temperature within a furnace under a high vacuum. The components are supported in the furnace upon a slip sheet carried by a glass pad which is, in turn, supported by a lower platen. The weight of an upper platen is transmitted through a slip sheet to the upper face sheet component. The upper face sheet component includes an internal passageway which is coupled to an inert gas supply to expand the passageway by superplastic forming. The upper wall surface of the passageway is restrained by the upper platen so that only the lower wall surface of the passageway is displaced and received in underlying recesses in the honeycomb core component. After expansion, the displaced wall surface is diffusion bonded to the honeycomb core component. Preferably, the upper face sheet component is fabricated from two sheets which are joined together by diffusion bonding after a strip-like pattern of a stop-off coating, e.g., boron nitride, is deposited on one face sheet using silk-screening techniques. Only the uncoated surfaces between the sheets are diffusion bonded together.
