Abstract
A fiber-reinforced metal composite material comprising a metal or alloy as the matrix and an inorganic fiber as the reinforcing material, characterized in that at least one element selected from the group consisting of elements belonging to the fourth or higher periods of the group (IA) in the periodic table, elements belonging to the fifth or higher periods of the group (IIA) in the periodic table, and Bi and In in the form of simple substance or organic or inorganic compound is incorporated into either one or both of the matrix metal or the reinforcing material in an amount of 0.0005 to 10% by weight (calculated in terms of the element) so as to enhance the mechanical strength of the composite material.
