摘要： PROBLEM TO BE SOLVED: To provide a printed wiring circuit board which can be made light in weight and high in mounting density. SOLUTION: The printed wiring circuit board includes a substrate 1 made of a carbon fiber reinforced aluminum alloy containing carbon fibers dispersed into an aluminum alloy matrix, an insulating film 2 provided on one side of the substrate 1, and a conductive film pattern 3 formed on the insulating film 2. Semiconductor elements 4 are mounted on the board. In this case, parts 5 of the substrate 1 on which the semiconductor elements 4 are mounted have a carbon fiber dispersion percentage higher than the other part thereof so that a thermal expansion coefficient of the semiconductor element mounted parts 5 is as low as that of the semiconductor element. Since the substrate 1 is made of a carbon fiber reinforced aluminum alloy, the substrate is light in weight. Further, since the parts of the substrate 1 corresponding to the mounted positions of the semiconductor element 4 have a high carbon fiber dispersion percentage and have a thermal expansion coefficient as low as that of the semiconductor element destruction of the element 4 caused by a thermal expansion difference therebetween can be prevented and high density mounting thereof can be realized.

摘要： PROBLEM TO BE SOLVED: To prevent an inorganic structural body from being broken by arranging a fibrous inorganic material adjacently to the porous inorganic structural body, impregnating a metal therein by the high-pressure casting method or the molten metal forging method to prevent non-uniformity in the local temperature due to the heat radiation into a jig, a or the like. SOLUTION: A metal such as aluminum alloy is impregnated in a porous inorganic structural body consisting of silicon carbide, aluminum nitride, silicon nitride aluminum oxide, or the like arranged with a fibrous inorganic material mainly consisting of aluminum adjacently thereto. As porous inorganic structural body, a ceramic sintered body or the like having pores capable of impregnating the metal, the strength of, for example, 10 MPa which is difficult to generate breakage is preferable. The fibrous inorganic material is an assembly of blanket, mat and the like formed of inorganic compound fiber, and is arranged to cover the porous inorganic structural body. The heat radiation from the porous inorganic structural body through a jig, a die, or the like is reduced in impregnating the metal, and the local non-uniformity in temperature is suppressed to obtain a uniform composite body.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of a machine member formed of a whisker reinforced alloy capable of manufacturing the machine member of relatively complicated shape more inexpensively than a conventional technology. SOLUTION: A manufacturing method of a machine member formed of a whisker reinforced alloy comprises a first preform process in which a whisker is formed into a plurality of simple shapes obtained by dividing an outline shape of a desired machine member to manufacture a plurality of preform stocks consisting of the whisker, a second reinforcement forming process in which a plurality of preform stocks are combined in an outline shape and fixed to form a reinforcement 1 consisting of the whisker, and a third casting process in which the molten metal 2' of a base alloy is poured into a mold 41 in which the reinforcement 1 is inserted, and pressurized to impregnate the molten metal 2' in the reinforcement, cooled and solidified to cast a composite material of the base alloy and the reinforcement 1. Because the composite material is formed in the outline shape of the machine member to be manufactured, the cut man hour and the material cost for the whisker can be reduced, resulting in the cost reduction.

摘要： PROBLEM TO BE SOLVED: To produce a laminated body composed of particles rigidly bonded each other and having an excellent quality at a low cost by mixing fibers with the particles at the time of thermal spraying to bond the particles to each other through fiber chips. SOLUTION: The fiber chips are preferably contained by 2-70 vol.% and preferably of 2-50 μm diameter, 50 μm length and aspect ratio of >=10. Flame 7 as a heat source is generated in an inner hole 3a of a gun main body 3 by sending a thermal spraying gas from a nozzle 5. A thermal spraying material 9 composed of the particles of a metal, a resin or the mixture and the fibers 11 of a metallic material, a carbon material or the mixture are previously mixed, charged into the nozzle 5, jetted and passed through the flame 7 to be melted. The fiber 11 is selected from a material having a higher m.p. than that of the thermal spraying material 9. By controlling the flame 7 to melt only the thermal spraying material 9, the thermal spraying material is bonded to each other and cooled to generate strong bonding force when the thermal sprayed mixture collides with the pedestal 13. The particle laminated body 15 is formed by lamination on the pedestal 13.

摘要： PROBLEM TO BE SOLVED: To obtain a composite material free from the deterioration of properties even if being applied with thermal stress, maintaining a low thermal expansion coefficient and high thermal conductivity and high in reliability by specifying the aspect ratio and volume packing ratio of carbon fibers dispersed into a matrix of aluminum or the alloy thereof. SOLUTION: Relating to the composite material aluminum or an aluminum alloy having high thermal conductivity is used as a metallic matrix, carbon fibers low in thermal expansion are dispersed, and as for the carbon fibers, the average value of the aspect ratio is regulated to 30 to 50, and the volume packing ratio is regulated to 20 to 35%. Therefore, anchor effect occurs between the carbon fibers and aluminum or the alloy thereof, its thermal expandability and thermal conductivity can be maintained without deteriorating the characteristics even if thermal stress is applied thereto, and its toughness can simultaneously be improved. As the aluminum alloy of the matrix, the one contg. 12 to 25 wt.% Si is suitable since the difference between the thermal expansion coefficient of the matrix and that of the carbon fibers is made small.
