Abstract

A composite material is made from alumina-silica type short fibers embedded in a matrix of metal. The metal is an al­ loy consisting essentially of between approximately 1.5% to approximately 6% of copper, between approximately 0.5% to approximately 2% of silicon, and remainder substantially alumi­ num. The short fibers may be all alumina short fibers, or may be all amorphous alumina-silica short fibers, or may have a sub­ stantial proportion of the mullite crystalline form included in them. The fiber volume proportion of the alumina-silica type short fibers may desirably be between approximately 5% and approximately 50%, and may more desirably be between ap­ proximately 5% and approximately 40%. And, in the desirable case that the fiber volume proportion of the alumina-silica type short fibers is between approximately 5% and approximately 20%, then the copper content of said aluminum alloy matrix metal is desired to be between approximately 2% and approxi­ mately 6%.
