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.

摘要： PURPOSE:To easily obtain a carbon/carbon composite material by subjecting a mixture contg. pitch fibers and carbonized fibers obtd. by making the pitch fibers infusible and carbonizing them to carbonization and compacting under uniaxial pressurization. CONSTITUTION:Carbonaceous coal or petroleum pitch is melt-spun by a known method to obtain pitch fibers having 5-100mum average diameter. The pitch preferably has 100-400 deg.C softening point and contains 60-100% optically anisotropic phase. Carbonized fibers are obtd. by making the pitch fibers infusible by treatment at 50-400 deg.C for 10-min to 20hr in an atmosphere of an oxidizing gas and carbonizing them by treatment at 350-1,000 deg.C for 10min to 5hr in a nonoxidizing atmosphere. A mixture contg. 100 pts.wt. of the pitch fibers and 100-1,900 pts.wt. of the carbonized fibers is carbonized and compacted under uniaxial pressurization to form a primary compact having 5-70vol.% porosity and 0.1-1.8g/cm bulk density. This compact is densified with a carbonaceous matrix.

摘要： PURPOSE:To obtain the title compound material having high strength, high elastic modulus and causing no delamination on the surface by precipitating carbon by gaseous phase thermal cracking and filling the voids of a carbon/ carbon compound material with the precipitated carbon, then coating the surface of the carbon/carbon compound material with the precipitated carbon. CONSTITUTION:A fabric or molded body is prepd. from bundles of many continuous carbon fibers, and carbonaceous pitch, phenol resin, etc., is impregnated thereinto, and the impregnated product is carbonized under a press. The tissue is made denser by repeating the impregnation/carbonization cycle necessary times. Thus, a carbon/carbon compound material constituted of 10-70vol.% molded body of carbon fibers and 5-80vol.% carbonaceous matrix, and having 10-55% void is produced. Then, the voids of the carbon/carbon compound material is filled with deposited carbon produced by the gaseous phase thermal cracking. The surface is further coated with carbon deposited by the gaseous phase thermal cracking. Thus, a carbon/carbon compound material is obtd.

摘要： PURPOSE:To obtain in a simple way a carbonaceous material having quality comparable to those of carbon/carbon composite materials by carbonizing, in a pressurized state, a ground mixture prepared by blending, in specified proportion, pitch-based carbon fiber and infusibilized fiber derived from treating pitch fiber. CONSTITUTION:A ground mixture prepared by blending and grinding (A) 20-95 pts.wt. of (i) infusibilized fiber derived from infusibilization treatment of pitch fiber and/or (ii) pre-carbonized fiber derived from pre-carbonization treatment of the above infusibilized fiber in an inert atmosphere at 350-800 deg.C (pref. 400-700 deg.C) and (B) 5-80pts.wt. of pitch-based carbon fiber is carbonized under pressure or by pressing and furthermore, if needed, carbonized or graphitized under normal pressure, thus obtaining the objective material. Said infusibilization treatment is pref. carried out under an oxidative gas atmosphere at 110-350 deg.C.

摘要： PROBLEM TO BE SOLVED: To provide a reinforced material for manufacturing a circular fiber reinforced composite material durable to the large centrifugal force and revolving at high speed. SOLUTION: In a circular fiber reinforced material provided with wefts R in the radius direction, warps in the circumferential direction and perpendicularly crossing yarns Z, at least the organization of an outer peripheral section is an organization in which the warps R are confounded with the perpendicularly crossing yarns Z and/or the organization in which the wefts are confounded with the perpendicularly crossing yarns A. Also in the organization provided with the warps and perpendicularly crossing yarns Z, at least the wefts of the outer peripheral section are passed outside the outer side perpendicularly crossing yarns positioned outside the diameter direction of the circular and also passed inside the inner side perpendicularly crossing yarns which are positioned on the inner side of the outside perpendicularly crossing yarns and confouded zigzag. The above-said respective organizations can be used alone or in combination for respective layers of multi-layer reinforcing organizations. The breaking strength of the outer peripheral edge of the fiber reinforced composite material when the large centrifugal force is applied can be increased by using the reinforced material of the above-said organizations.
