'A method for producing a silicon carbide - silicon matrix - ceramic, shaped ceramic and silicon carbide, - - - ceramic silicon matrix composite material'

摘要

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° C. to about 1800° C. in an inert atmosphere or vacuum. Silicon carbide powder can also be incorporated in the preform structure.
