Abstract : The second generation beta titanium alloys, Beta III, RMI 38-6-44 and TMCA 88-23, were furnished in foil and fabricated into honeycomb core. All three alloys responded well to the core manufacturing process. Thermal effect studies showed that all of the beta titanium alloys were relatively unaffected by high temperature, long time exposures when in foil form. Sheet forms resulted in grain growth under the same conditions. The Rohr Industries, Inc. proprietary LID(TM) bonding process showed the highest strength joints of all other systems tested. Sandwich panels made with the three beta titanium cores bonded to Ti 6Al 4V faces were measured in all sandwich test modes. The data were compared with sandwich structure made with the same joining system except with Ti 3Al 2.5V core. Results showed that significant strength improvements can be realized by using beta titanium core. Projections also show that material cost economies may be realized by using beta titanium core.
