However, in these methods, the content of the ceramics as a reinforcing material cannot be increased, or a large pressurizing device is required, or it is difficult to form a near net, and the cost is extremely high. It was not satisfactory.

う問題があった。However, in this method, since the aluminum alloy permeated into the preform seeps out considerably from the preform, the aluminum alloy penetrated by applying a carbon powder barrier material to the surface of the preform. Although it suppresses the outflow, even if the applied barrier material is carefully removed on the surface of the formed composite material,
Since the carbon powder as a barrier material has strong adhesion and is extremely fine, there is a problem that a large amount of carbon powder remains as dust.
