摘要： PURPOSE:To obtain a carbon material or a carbon/carbon composite material having dense texture and very little cracks by using a carbonaceous pitch or impregnated material produced by impregnating carbonaceous pitch into a carbon fiber tow and subjecting the material to hot hydrostatic pressing under specific condition. CONSTITUTION:A carbonaceous pitch or an impregnated material produced by impregnating carbonaceous pitch into a carbon fiber tow is put into an open vessel for holding a treating object and heat-treated under hydrostatic pressure with a hot hydrostatic press under the condition to keep the production rates of H2 and CH4 in the produced gas to a level not higher than 10mol/hr per 100g of the carbonaceous pitch and, if necessary, the heat-treated product is further carbonized or graphitized. A carbon material is produced from the carbonaceous pitch and a carbon/carbon composite material is produced from the impregnated material by the above process. The hot hydrostatic press is preferably provided with an evacuation mechanism.

摘要： PURPOSE:To obtain the subject woven fabric having little fluffs by melt-spinning a carbonaceous pitch, infusibilizing the fiber, subjecting to the primary heat- treatment at a specific temperature, forming a woven fabric with the obtained fiber and subjecting the fabric to the secondary heat-treatment at a specific temperature. CONSTITUTION:A carbonaceous pitch having a softening point of 100-400 deg.C (e.g. coal or petroleum pitch) is spun in molten state and infusibilized in an oxidizing gas atmosphere at 50-400 deg.C. The infusibilized fiber is subjected to the primary heat treatment in an inert gas at 650-2500 deg.C to obtain a primary heat-treated fiber having a tensile strength of >=250kgf/mm and an elongation at break of 0.4-10%. A two-dimensional or three-dimensional woven fabric is produced by using the primary heat-treated fiber and the fabric is subjected to the secondary heat-treatment at a temperature not lower than 700 deg.C and higher than the primary heat treatment temperature to obtain the objective fabric free from baking warpage.

摘要： PROBLEM TO BE SOLVED: To provide a first wall and a divertor plate which are installed so that the wall and divertor can be faced oppositely to the plasma of a nuclear fusion device and has a high thermal shock resistance. SOLUTION: A carbon fiber-reinforced composite carbon material is integrally constituted by laminating a unidirectional carbon fiber-reinforced material and tri-directional carbon fiber-reinforced material upon another in the thickness direction so that the carbon fibers substantially oriented in the thickness direction can become continuous in the thickness direction. A first wall and a divertor plate are positions adjacently to the unidirectional carbon fiber- reinforced section so that the wall and plate can be faced to the plasma of a nuclear fusion device constituted mainly of the carbon fiber-reinforced composite carbon material in which a metal is joined to one surface of the unidirectional carbon fiber-reinforced section substantially perpendicular to the thickness direction of the section or a metallic tube is buried in the tri-directional carbon fiber-reinforced composite carbon material.

摘要： PROBLEM TO BE SOLVED: To obtain a three-dimensional woven fabric tapered in thickness in the weaving direction and having a dense and uniform woven tissue easy in production and not causing the waste of the material. SOLUTION: In the tapered part 32 of the three-dimensional woven fabric woven from warps 1Y-13Y collected into plural groups, wefts 14X-18X divided into plural layers, and entangling yarns 26Z, 27Z for binding the wefts of outer layer, the plural groups of the collected warps are successively divided for each group. The thickness of the tapered part 32 is tapered in the weaving direction. New wefts are inserted between the divided warps to increase the number of layers of the woven fabric from a thin part 31 to a thick part 32. The thickness of the woven fabric is increased in the tapered state. Since the number of layers increases with the increase of the thickness, it can be prevented that the tissue is loosened on the thick side.
