IPC: C04B35/80
Filed: 2001-03-30
Abstract: PROBLEM TO BE SOLVED: To provide a method of producing a ceramic-based composite material, by which the ceramic-based composite material having a smooth surface can be obtained and the high temperature strength, the heat resistance and the hermetic property of the ceramic-based composite material can be improved. SOLUTION: A precursor solution for a matrix is effectively impregnated into each fiber 3x, 3y, 3z constituting a fiber reinforced body M1 by impregnating the solution into the fiber reinforced body M1 under a reduced pressure or a high pressure so as to reduce the amount of a residual gas in the fibers when the precursor solution for the matrix is impregnated into the fiber reinforced body M1. The fiber reinforced body impregnated with the precursor solution is dried while preventing the leakage of the precursor solution from the matrix, caused by the evolution of the gas. Thereby, the surface is made smooth, the gas in the precursor solution for the matrix is removed and the survival of air bubbles at the time of sintering is inhibited.  Thus, the formation of pores in the matrix caused by the presence of the air bubbles at the time of sintering can be suppressed, and the highly hermetic ceramic composite material can be obtained in a high yield.
