The program was conducted to determine and extend the potential of wirewound tungsten composites for analysis, design, and fabrication of rocket hardware through characterization of its mechanical, thermal, chemical, and physical properties. Specimens, designed specifically for desired structural and thermal analytical properties, were fabricated by previously developed rocket nozzle techniques of plasma-spraying and filament reinforcement. Thermal and mechanical properties were determined for the temperature range of 70 to 4, 000F 21 to 2,210C. Residual test specimen material was evaluated to characterize physical and chemical properties of both as-composited and elevated temperature exposed wire-wound tungsten. Suitable test methods for nondestructive examinations were determined, and a material specification was prepared based on the program results.
