Research and Exploratory Development on the Fabrication and Characterization of Fiber Reinforced Light Metal Alloy Composites

Abstract

Discontinuous beta-SiC whiskers and chopped C filaments were used as a reinforcement for strengthening 7178 and 2024 Al alloys. The C fibers were coated with Cu to improve wetting. Tensile properties of a 25 v/o beta-SiC 2024 Al composite were increased three times over the matrix strength at room temperature and ten times at 800F. Tensile properties in the transverse direction were at least equal to the matrix strength at temperatures up to 800F. Ti-10V composites reinforced with SiC filaments were consolidated by activated pressure sintering. The samples produced were not fully dense. Consolidation temperature or time at temperature could not be increased since the reaction between the matrix and filaments would be too severe.
