Abstract
Improved fiber-reinforced metallic composite material comprises as a matrix a metal alloy having a lower melting point than magnesium and being chemically inactive (e.g. zinc, cadmium, indium, tin, thallium, lead, bismuth and polonium) or and as a reinforcement inorganic fibers of 15 to 70% by volume, in which the metal alloy composing the matrix contains 0.01 to 10% by weight of one or more metals of group IA or group IIA (except beryllium) in the periodic table (e.g. lithium, sodium, potassium, rubidium, cesium, francium, magnesium, calcium, strontium, barium and radium). The composite material has improved mechanical strength, and is useful as a material for various parts and apparatuses in various industrial fields such as aerospace, atomic power and automobile industries.
