  • Method of manufacturing CMC components using boron carbide
    Patent number: 11578774
    Abstract: A method of manufacturing a ceramic matrix composite component includes pressure casting a fibrous preform with a slurry comprising boron carbide and densifying the fibrous preform using a liquid source of carbon. The method may include forming holes in the fibrous preform before pressure casting the fibrous preform with the slurry. The method may also include sintering the boron carbide after the pressure casting. In various embodiments, the sintering may be performed before the densifying.
