Abstract : Manufacturing methods and design procedures were developed for fabricating details and vacuum brazing of TZM (Mo-O-5Ti-0.07Zr) molybdenum and D-36 D-36 (Nb-10Ti-5Zr) niobium alloy honeycomb sandwich panels. These included the marforming of thin sheet, the welding and finishing of honeycomb core and the high temperature vacuum brazing of honeycomb sandwich panels. Panels simulating a heat shield and a structural application on aerospace vehicles were designed, fabricated and tested at temperature up to 2600 F. The capability of fabricating, coating and utilizing brazed niobium sandwich panels on aerospace vehicles, with the required design procedures for application at temperatures up to 2400 F, was demonstrated. Only partial success was achieved with the TZM molybdenum alloy. (Author)
