- 1 - ABSTRACT The invention provides a process for preparing a fiber-reinforced metal composite material which comprises (1) combining inorganic fibers comprising alumina as a main component and silica as a secondary component, with an aluminum alloy containing at least one of the elements copper, silicon, magnesium and zinc as a secondary component, at a temperature of not lower than the melting point of the alloy to form a composite, (2) subjecting the composite to a solid solution treatment, (3) quenching the treated composite and (4) optionally tempering the quenched composite at a temperature of from 100 to 250°C. The resulting fiber-reinforced metal composite material has improved mechanical properties and can be produced economically.
