Abstract (en)

A composite material is made from silicon carbide short fibers embedded in a matrix of metal. The fiber volume proportion of the silicon carbide short fibers is between approximately 5% and approximately 50%. The metal is an alloy consisting essentially of between approximately 2% to approximately 6% of copper, between approximately 2% to approximately 4% of magnesium, and remainder substantially aluminum. The fiber volume proportion of the silicon carbide short fibers may more desirably be between approximately 5% and approximately 40%; the copper content of the aluminum alloy matrix metal may more desirably be between approximately 2% and approximately 5.5%; and the magnesium content of the aluminum alloy matrix metal may more desirably be between approximately 2% and approximately 3-5%.
