Title:
TREATMENT FOR MAKING CARBON COMPOSITE REINFORCED WITH CARBON FIBER RESISTANT TO OXIDATION
Document Type and Number:
Japanese Patent JP2607409
Kind Code:
B2
Abstract:
PURPOSE: To provide a treatment process for making a carbon composite reinforced with carbon fibers (C/C material) resistant to oxidation because the formation of silicon carbide layer is inhibited at specific sites, while homogeneous and dense layer of silicon carbide is formed on the other sites.
CONSTITUTION: The C/C base material is coated with a thermally decomposable thermo-setting resin to form gas-insulation membranes. Then, the surfaces of the base material are coated with silicon carbide layers by the conversion method where the material is buried in a powder composition of a silicon source and a carbon material with heating at 1,600 to 2,000°C in a nonoxidative atmosphere. Further, in the constitution stated above, the material is covered or filled with a carbonaceous powder or with a mixture thereof with a thermally decomposable thermo-setting resin at specific sites for the coating treatment.
