PROBLEM TO BE SOLVED: To reduce the weight of a metal-ceramics composite composed essentially of aluminum alloy and also to improve the heat resistance of this composite material. SOLUTION: This metal-ceramics composite can be produced by allowing an aluminum alloy as base material to penetrate into a preform constituted of ceramic fibers or grains as reinforcement. At this time, the aluminum alloy is an alloy prepared by incorporating >=10% Si and >=1% Mg into Al, and, as to the method for penetrating metal, the aluminum alloy melted at 700-850 deg.C is allowed to penetrate into the preform at >=50MPa pressure. |
