Mg alloys possess the advantages of low density and high damping capacity and they are conventionally used in the aerospace and aviation industries. The mechanical properties of Mg alloy matrix composites reinforced with continuous fibers, short fibers or whiskers and particles are improved over those of unreinforced Mg alloys. The hybrid composite, that means its reinforcements are produced by an appropriate combination of short fibers (or whiskers) and particles, can satisfy the demands for reducing cost and improving properties. So the interest in Mg alloy matrix hybrid composites is increasing recently. In order to gain more data of this new kind of composites and to search for a better combination of different reinforcements, a Mg alloy matrix composite reinforced by hybrid SiC whiskers and B{sub 4}C particles was fabricated and its mechanical properties and damping capacity were studied in this paper.
