MANUFACTURING METHODS AND DESIGN PROCEDURES OF BRAZED REFRACTORY METAL HONEYCOMB SANDWICH PANELS

Abstract

Honeycomb sandwich panels using Mo and Nb core and facings can be brazed to provide lightweight structural coverings for high temperature application on an aerospace vehicle. The panel configurations selected for fabrication simulate a hot structural and a radiant heat shield application . M (Mo-0.5Ti-0.08Zr) Mo and D-36 (Nb-10Ti-5Zr) Nb alloys were chosen for use on the program. Special tools and procedures were developed to fabricate the honeycomb core. All Mo welding will be accomplished by electron beam welding. A 4200 F cold-wall vacuum furnace will be used to braze the honeycomb test panels. A quartz-lamp facility will be used to heat the panels for structural testing. Thermal-cyclic and sonic fatigue tests will be performed on heat shield test panels. A 4000 F cold-wall vacuum test chamber will be used to determine material and honeycomb proporties.
