Abstract : Composites containing 5 micron-diam graphite fibers were made with Al, Al-4% Cu, and 50 Co50 Ni alloy matrices. Al matrix composites made by heating above the mp of Al produced similar yield strengths and ultimate yield strengths less than that of pure Al. The graphite fibers were segregated in layers throughout the specimen. Composites made by sintering the Cu-Ni matrix gave low tensile strengths for the ascomposited specimens, but the hot forged and rolled specimens showed higher values. Porosity resulting from sintering reduced the strength, although hot working reduced the porosity.
