摘要： PURPOSE:To produce the title high-quality fiber-reinforced composite material having uniform characteristics by integrally dispersing inorg. short fibers in the fiber gap of a cloth consisting of inorg. continuous fibers to integrate the materials, infiltrating a molten metal into the material, and then solidifying the metal. CONSTITUTION:The inorg. continuous fibers 1 as warp and the org. continuous fibers 2 as weft are plain-woven into a cloth 3. A flowable blend 7 consisting of inorg. short fibers 4, an inorg. binder 5, an org. additive 6, and water is prepared in a vessel 10. The blend is poured onto the filter 12 of a vessel 13 vacuum-sucked by a vacuum suction port 11 to laminate the inorg. short fibers 4 on the filter 12. The cloth 3 is placed on the laminated inorg. short fibers 4 to laminate the fibers 4 on the cloth 3 in the same way, and a fibrous laminate 8 consisting of the integrated fibers 1, 2, and 4 is obtained. The laminate 8 is roasted to form a composite fiber formed product 9 wherein the inorg. continuous fibers 1 are unidirectionally and regularly arranged in the formed product of the inorg. short fibers 4. The product 9 is dipped in the molten metal 24 in a metallic mold 20, and pressed by a plunger 23. Consequently, the molten metal is infiltrated into the product 9, and then solidified.

摘要： PURPOSE:To obviate the dimensional change of a fiber-reinforced metal during use, by subjecting a fiber-reinforced metal in which light metals are used as base material to a treatment consisting of heating up to service temp. or above and holding. CONSTITUTION:The treatment consisting of heating to service temp. and holding is applied to the fiber-reinforced metal formed by using light metals as a base material and compounding a fiber reinforcement with the base material. Owing to this treatment, local metallographic changes of the fiber-reinforced metal can be completed before use (before finish working). The fiber-reinforced metal after the above treatment is practically free from dimensional change even if used at the prescribed temp. for a long period because dimensional change due to temp. rise during use is previously taken into account. Accordingly, dimensional accuracy of the parts and products of various structures made of this fiber-reinforced metal, such as piston, etc., can be maintained at a high level.

摘要： PURPOSE:To improve remarkably the wear resistance of cam parts by making the cam parts composite with fibers and binding securely the cam parts and a shaft part. CONSTITUTION:Fiber moldings 27 are disposed in the positions corresponding to cam parts 50a of centrifugal casting molds 41, 42 having casting spaces 43 for forming a cam shaft. The molds 41, 42 are rotated coaxially with the rotating center of a cam shaft 50 to be cast to act centrifugal force to the molten metal supplied into the spaces 43. The molten metal is penetrated into the spaces among the fibers of the fiber moldings 27 by the centrifugal force by which the cam parts 50a and the shaft part 50c are securely bound.

摘要： PURPOSE:To prevent penetration of a molten metal into a cooling hole and deformation and to provide a denser, stronger and lighter piston in aluminum casting of the piston by forming a core for internal cooling of a molten salt casting, disposing the core in a casting mold and performing high-pressure casting. CONSTITUTION:Molten salt 31 is poured into the core mold 26 in a molding flask 25 and an annular molten salt core 21 is manufactured. The core 21 is held by a suitable means, for example, by a holding material 20 to a cast annular member 19 having wear resistance and is thus disposed in a casting mold for a piston. Molten aluminum 34 is cast A' under high pressue into a casting mold 11 by a plunger 14. The core 21 prevents penetration and deformation with the high-pressure aluminum and therefore said core forms a good cooling hole. The piston structure is made dense by the high-pressure pouring, by which the strength is improved and the weight is reduced. The insert salt is washed away through a suitable cast hole 35.

摘要： PURPOSE:To obtain a hollow shaft having high dimensional accuracy easily, by supplying the molten metal in a sleeve forcibly into the central part of a casting mold under rotation by the extruding operation of a plunger. CONSTITUTION:A sliding member 18 fixed to a sleeve 16 is brought into contact with the end part of a casting mold 15 to communicate the inside of the mold 15 and the inside of the sleeve 16 through an opening 15a for supplying molten metal and the member 18. Molten metal 30 is supplied through a charging port 19 into the sleeve 16 and a plunger 17 is advanced to supply the metal 30 into the mold 15. The metal 15 is formed into a hollow part by the centrifugal force developed by the rotation of the mold 15. The sleeve 16 is immediately detached from the mold 15 to prevent the adverse influence by abrasion, oscillation, etc. The hollow shaft having high dimensional accuracy is thus obtained easily.
