Abstract : Parameter studies indicated that powder metal bars of Co were reinforced by 18.6 volume % 10 mil diameter continuous W wires. The room temperature strength was increased from 48,500 psi to 85,000 psi by adding W wires. The elevated temperature (2000 F in vacuum) short time tensile strength was increased from 2,700 psi for Co to 23,600 psi by adding 18 volume % continuous 10 mil diameter W wires to a Co matrix. Parameter studies are in progress to determine the effect of wire diameter, wire length, wire spacing, wire orientation, and wire-to-matrix bond strength. Hot pressing produced composites that were 96 to 98% of theoretical density while cold pressing followed by sintering produced composites that were 80 to 90% of theoretical density depending on matrix composition.
