This report is a summary of the investigations con ducted during this bimonthly report period for the development of a process for producing continuous filaments of metal-glass composites. Several techniques were investigated as possible means of introducing molten beryllium into the forming zone of glass fibers being drawn from glass tubing. Protective coatings on beryllium wire and protection tubes inside the glass tube have been tried as means of limiting the reaction time between beryllium and glass. Only a few short lengths of beryllium-glass composite fibers were obtained. The reaction time has not been sufficiently reduced, but the general techniques warrant further consideration. Preliminary experiments have also been made on means of removing glass coatings from handdrawn beryllium-glass composites. Molten sodium carbonate appears promising for chemically removing the glass. Work on copper-glass composites was limited to improvements in apparatus. Continuity testing equipment was improved and new winding equipment was installed to facilitate fiber removal, inspection and evaluation. Author
