A simple process was developed to fabricate ceramic-reinforced copper and silver matrix composites by electroless plating and hot pressing at 873 K and 300 MPa, in air. Composites were produced containing 10 to 40 vol pct ceramic reinforcements of different sizes and shapes including silicon carbide whiskers (SiC"), alumina particles (Al^sub 2^O^sub 3p^), carbon short fibers (Carbonsf), and Saffil short fibers (Saffilsf) (3.8 pct SiO2-96.2 pct A1203) uniformly distributed within the matrix. The hardness and bending strength of the composites were much higher than those of the pure matrices. The electrical conductivity, measured by a four-point probe method, was similar to that of ...
