Abstract
A process for preparing a fiber-reinforced metal composite material which comprises (1) combining an inorganic fiber comprising alumina as the main component and silica as the secondary component with an aluminum alloy containing at least one of copper, silicon, magnesium and zinc as the secondary component at a temperature of not lower than the melting point of said alloy to make a composite, (2) subjecting said composite to solid solution treatment, (3) quenching the treated composite and (4) optionally tempering the quenched composite at a temperature of from 100 to 250.degree. C.
