Abstract
A method for making a composite material. Porous reinforcing material such as fiber material is charged into a container which has an opening; then substantially all of the atmospheric air in the container and in the interstices of the reinforcing material is replaced by substantially pure oxygen; and then molten matrix metal is admitted into the container through the opening so as to infiltrate into the interstices of the reinforcing material. During this infiltration the oxygen within the container and in these interstices is absorbed by an oxidization reaction, and thus substantially all the gas present within the interstices of the reinforcing material is disposed of, thus not hampering the good infiltration of the molten matrix metal into the reinforcing material. Thus a high quality composite material is formed. The oxidization reaction may either be with the molten matrix metal itself, or with a getter element provided within the container.
