摘要： PURPOSE:To form a fiber reinforced composite member without the need for a die by forming a preforming body from a reinforced fiber, dipping it in a molten matrix after removing an air, removing the excess molten matrix and solidifying this molten matrix. CONSTITUTION:A cylindrical perform 100 is formed from a reinforced fiber and after holding the preform 100 by a holding part 50 by opening a cover member 2 a pressure container 1 is sealed. The air among the fibers of the preform 100 is removed by reducing the pressure by a vacuum pump 12. An aluminum molten metal 200 is input into a crucible 3, melted by heating by a heater 4, the holding part 50 is descended and the preform 100 is dipped into the aluminum molten metal 200. A valve 11 is closed, a valve 13 is opened, a pressurized air is fed from a compressor 14 and the aluminum molten metal 200 is impregnated into the preform 100. The preform 100 is lifted by stopping the pressurization and returning to the atmosphere and sticked aluminum molten metal is recovered by its dropping. After the preform being nearly solidified the cover member 2 is opened to take out a fiber reinforced composite member. A die is thus made unnecessary and the impregnation is facilitated with high temp.

摘要： PURPOSE:To obtain a formed body which does not break even if used for joining of members different from each other in coefficient of thermal expansion by changing the aspect ratios of whiskers on one end face and other end face sides of a formed body in the titled formed body, for use in supporting electrodes, etc., for semiconductor device, in which ceramic or C whiskers are dispersed. CONSTITUTION:A fiber-reinforced metallic formed body 1 is the one disklike in the whole shape in which SiC whiskers, for example, are dispersed in a copper matrix and, in this formed body 1, the lower part A, central part B and upper part C are filled with Si whiskers having aspect ratios (ratio of length to diameter) of 80-100, 60-80 and 40-60 in 30%, 40% and 50% volume content, respectively. In order to manufacture the formed body 1, the whiskers in which aspect ratios are made to vary by changing grain growth conditions in a whisker fiber making process are classified into the above mentioned large, medium and small. The above whiskers are laminated in a die 5 in the above order by equivalent weights, which is pressurized by a punch 6 into a preformed body. This preformed body is put into a die, into which molten copper is poured to undergo high pressure casting immediately by a punch.

摘要： PURPOSE:To form an intricate flow in a mixing cavity and to permit thorough mixing of an additive and molten metal by limiting the sectional area of a gate communicating with a molding cavity and mixing cavity with respect to the sectional area of a gate communicating the mixing cavity and injection sleeve. CONSTITUTION:The molten metal injected from the injection sleeve 14 of a die casting machine having the mixing cavity 5 flows through the 2nd gate 7 into the mixing cavity 5. The molten metal is mixed with the additive 23 in the mixing cavity. The 1st gate 4 communicating the mixing cavity 5 and the molding cavity 3 is formed to 5/6-1/5 the sectional area of the 2nd gate 7 communicating the mixing cavity 5 and the injection sleeve 14 and therefore, the molten metal admitted into the cavity 5 from the injection sleeve 14 is pressurized again to form the intricate flow. The additive 23 and the molten metal are thoroughly mixed so that the generation of the ununiform dispersion of the additive 23 and the insufficient wetting of the additive 23 and the metal is obviated.
