Abstract
Matrix composites and especially metal matrix composites are formed by coating a foam with a metal or ceramic to form a continuous structure from which the foam material is removed by pyrolysis. If this structure is composed of a metal it is subjected to treatment to transform the metal to a ceramic and the resulting ceramic structure is then filled with another material such as a matrix metal. The product is then compacted and heat treated if desired. The coating of the foam and the filling of the porous ceramic structure are effected preferably by low temperature arc vapor deposition.
