Research and Development of Discontinuous Fiber Reinforced Light Alloy

Abstract

Two approaches to the preparation of titanium alloy composites reinforced with silicon carbide fibers without objectionable fiber-matrix reaction were studied: (1) interposing a protective coating of cerium monosulfide between the fiber and matrix; (2) activated pressure sintering of the metal hydride with the fibers to produce consolidation under less severe conditions. Composites of 2024 aluminum reinforced with discontinuous graphite fibers (Thornel 75 and Modmor Type 1) were prepared by liquid-phase hot pressing of metal powder-fiber green bodies. Alignment of fibers was obtained by hot extrusion of the consolidated composite or camphene extrusion and layup of the original green body.
