PURPOSE:To provide a carbon fiber reinforced carbon material having high oxidation resistance and coated texture properties. CONSTITUTION:A laminate comprising a first coated layer (100-300mum film thickness) composed of a polycrystalline SiC coating film having an inclined function, a second coated layer (10-50mum film thickness) composed of an amorphous or finely polycrystalline SiC coating film and a third coated layer (5-20mum film thickness) composed of a B2O3-SiO2 glass coating film is formed on the surface of a base of a carbon fiber reinforced carbon material. The carbon fiber reinforced carbon material shows high oxidation-resistant performances of 0.04 % final oxidation atmosphere. |
