Abstract
RECENT DEVELOPMENTS IN THE MANUFACTURE OF METAL MATRIX COMPOSITE PRECURSORS BY PHYSICAL VAPOR DEPOSITION TECHNIQUES HAVE CREATED AN OPPORTUNITY TO FABRICATE HIGH-QUALITY, FINE-GAGE COMPOSITE WIRES HAVING PRECISE DIMENSIONS AND FIBER VOLUME FRACTIONS. SPECIALLY DESIGNED DIES WILL BE USED TO DRAW ION-PLATED GRAPHITE/ALUMINUM AND GRAPHITE/MAGNESIUM COMPOSITE TAPES INTO 1.8-MM DIAMETER COMPOSITE WIRES AND THE MATERIALS WILL BE CHARACTERIZED IN TERMS OF MECHANICAL PROPERTIES, DENSITIES, AND MICROSTRUCTURES. THE FEASIBILITY OF PRODUCING LOW-DENSITY, HIGH-MODULUS, HIGH-STRENGTH WIRES HAVING PRECISE DIMENSION AND A ZERO COEFFICIENT OF THERMAL EXPANSION (CTE) WILL BE DEMONSTRATED FOR ARBITRARY LENGTHS. DESIGN GUIDELINES WILL BE ESTABLISHED FOR A PILOT-SCALE PROCESS IN WHICH A PARAMETRIC OPTIMIZATION CAN BE CARRIED OUT (PHASE II).
