The purified carbon fibers are molded into the desired shape on a tool or in die with infiltrating the matrix. The molded member packed with carbon fibers and carbon material of the matrix are either independently or simultaneously graphitized and then high-purification under halogen gas atmosphere. According to the present process, the metal impurities can be very low contents.

摘要： A mandrel for producing quartz glass, comprising at least two columnar or cylindrical, carbon fiberreinforced carbon composite material made members joined in series by screw thread parts. The mandrel is carbonimpregnated and/or carbon-coated on the screw thread parts, and, in addition, may be provided with reinforcing members on the outer sides of the screw thread parts. Quartz glass fine particles obtained by flame-hydrolyzing a volatile silicon compound are deposited, using this mandrel, on the surface of a heat-resisting substratum or on a starting rod at the end of the mandrel to easily form a large porous quartz glass mother material, the porous quartz glass mother material is dehydrated and transparently vitrified to produce a large optical fiber mother material, and further the optical fiber mother material is drawn to produce a low-cost, high-precision optical fiber. In addition, a columnar or cylindrical mandrel for producing quartz glass is disposed at the center of a heat-resisting mold, is filled with silicon dioxide power, and melt in a heating furnace for vitrifying, thereby producing a large, high precision quartz glass body at low costs.

摘要： The present invention is directed to a single crystal pulling crucible of carbon fiber reinforced carbon composite material formed by the filament windings by combination of axially reinforced layers as well as circumberentially reinforced layers, which combination is given in two or more sets, and to the producing method thereof. The circumferentially reinforced layers resist a force tending to exapand a drum portion of the crucible, and the axially reinforced layers resist a force tending to push down a bottom of the crucible. The axially reinforced layers extending from the bottom portion to the drum portion can be formed by at least either of a level winding of a contact angle of 0.degree. to 10.degree. with respect to the center axis and a poral winding, and the circumferentially reinforced layers in area adjacent to the drum portion out of the drum portion and the bottom portion can be formed by at least either of a parallel winding of a contact angle of 70.degree. to 90.degree. with respect to the center axis and a helical winding. When the axially reinforced layers cover the center of the bottom portion, an integral crucible of C/C composite material with no hole is provided. When the surface of the C/C composite material is impregnated and covered with a pyrolytic carbon, improved resistance to forming SiC is provided.
