ABSTRACT:
A method is described for making a shaped silicon carbide-silicon matrix composite. A confined carbon fiber preform is infiltrated with sufficient molten silicon metal at a temperature in the range of from about 1400.degree. C. to about 1800.degree. C. in an inert atmosphere or vacuum. Silicon carbide powder can also be incorporated in the preform structure.
