  • Silicon carbide coated carbon composite material and method for making same
    Patent number: 5462800
    Abstract: A silicon carbide coated carbon matrix/carbon fiber composite material is provided. The carbon composite base material, coated with silicon carbide, comprises a siliconized layer and a non-siliconized layer. The siliconized layer comprises silicon carbide matrix and non-siliconized carbon fibers. The siliconized layer also has a non-planar interface with a series of elongated protrusions penetrating into the surface the of non-siliconized layer. A gas-permeable intermediate coating formed on the carbon composite material can help produce such a siliconized layer.
