A method of depositing ceramics such as carbon or SiC directly into the structure of a molded product using a hydrocarbon gas such as SiC or a gas such as SiH 4 or SiCl 4 as a raw material.
It is necessary to increase the strength. Here, the carbonaceous resin refers to a resin mixed with another resin such as a phenol resin or a furan resin alone, a mixed resin thereof, or an epoxy resin. To lower the viscosity during impregnation,
Cutback with a solvent such as methyl ethyl ketone, methanol or xylene, or heating can also be performed. The carbonaceous pitch is a coal-based or petroleum-based pitch having a softening point of 100 to 400C, preferably 150 to 350C. As the carbonaceous pitch, any of an optically isotropic pitch and an anisotropic pitch can be used, but a pitch having an optically anisotropic phase content of 60 to 100% is particularly preferably used. The pitch impregnation is achieved by heating and melting, but it can be cut back with a solvent to reduce the viscosity during the impregnation. As the solvent, an aromatic hydrocarbon, pyridine, quinoline or the like can be used. The organometallic polymer is a precursor of at least one ceramic selected from the group consisting of carbide ceramics, nitride ceramics, and oxide ceramics. Specific examples include polycarbosilane, polysilazane, polysilastyrene, metal alkoxide, and alkyl metal. In the resin impregnation method, densification is achieved by repeating impregnation and heat treatment (carbonization or conversion), and in the CVI method, densification is performed over a long time.

Since one, two, or three are present, the impregnation proceeds further as shown by the arrows, and is sufficiently densified to achieve high density. From the viewpoint of strength, although the fiber content decreases in the Z direction (thickness direction) and a slight decrease in strength occurs, in the X direction (vertical direction) and the Y direction (horizontal direction), a conventional three-dimensional structure is used. The strength is equal to or higher than that of the woven fabric, and there is no problem in practical use. The structure of the three-dimensional fabric of the present invention is applicable even in the case of a cylindrical coordinate system. In this case, for example, the X direction is the radial direction, and the Y direction is the circumferential direction.
