Abstract: PURPOSE:To permit easy removal of a titled material from a metallic mold by interposing a powder or granular material which is not sintered at the temp. at the time of compounding between an assemblage of reinforcing fibers and the mold prior to pouring of a molten metal into the mold. CONSTITUTION:The assemblage 2 of the reinforcing fibers is put into a metallic pipe 4 and the pipe is disposed in the metallic mold 1. The nonsinterable powder or granular material 3 is packed between the mold 1 and the pipe 4. The melt 5 of the metal which is the matrix is poured into the pipe 4 and is pressurized by a plunger 6 by which the molten metal is impregnated into the assemblage 2 and is solidified therein. The nonsinterable powder or granular material 3 is discharged and a fiber reinforced metallic composite material FRM is taken together with the pipe 4 out of the mold 1 after the molten metal 5 solidifies, i.e., when the FRM is obtd. The pipe 4 is thereafter removed by cutting or stripping and the FRM is taken out. The discharge of the material 3 can be easily executed by separating the mold 1 and a base 7 and giving light impact to the mold 1 by a hammer or the like.

Abstract: PURPOSE:To provide a preform material which does not require special devices such as containers, filament winding device and other devices and permits deformation such as bending by putting a cylindrical braid on an assemblage of reinforcing fibers to form said material. CONSTITUTION:The cylindrical braid 2 is put on the assemblage 1 formed by paralleling the continuous fibers of the reinforcing fibers in one direction to a bundle shape to form the preform material. The cross sectional shape of the assemblage 1 is made into a circular or polygonal shape or may be made into so-called irregular sectional shapes such as I, L and Tee shapes as shown in the figure. The reinforcing fibers constituting the assemblage 1 are, for example, carbon fibers, alumina fibers, etc. The braid 2 imparts a shape retaining characteristic to the preform material to prevent the unraveling of the assemblage 1 and consists preferably of the above-mentioned reinforcing fibers. The preform material can be made into an FRM by putting the preform material into a casting mold, pouring the melt of a metal which is a matrix into the casting mold, pressurizing the melt to impregnate the metal into the preform material and solidifying the melt.

Abstract: PURPOSE:To enlarge the application range of fiber reinforced metallic material by extruding fiber reinforced metallic material with performing a metallic coating with using a die. CONSTITUTION:The blank 1 of fiber reinforced metallic material (FRM) which combines a metal and the short fiber for reinforcement is prepared in advance. The bank 1 is easily formed by a hot press method, etc. The metal ingot of the same group matrix metal is arranged on one end part of the blank FRM1 and also a preheating is performed at the prescribed temp. The blank FRM1 is then put into the die 3 with its metal ingot part ahead and subjected to extrusion work gradually by a plunger 4. In this case the metal ingot is fed little by little on the surface of the blank FRM1 and the surface is coated by metal layer 5. Due to the product FRM being obtd. with its surface being coated by the metal layer 5 the impact resistance of FRM and the joining to other members are increased and the application range of FRM is enlarged.

Abstract: PURPOSE:To obtain a fiber-reinforced metal with small dies and a small capacity heat source in a short sintering time by adding powder of a metal having a sufficiently lower m.p. than a matrix metal to a mixture of powder of the matrix metal with fiber for reinforcement, preliminarily sintering them, and carrying out sintering. CONSTITUTION:A powdered mixture of a matrix metal or alloy with a metal whose m.p. is several 100 deg.C lower than the m.p. of the matrix metal or alloy, e.g., a powdered mixture of Cu with Sn is mixed with fiber of carbon or the like, packed into dies for molding, and preliminarily sintered by heating in a heating furnace while applying a pressure. The misture of said 3 kinds of substances may be packed into a suitable container, heated in a heating furnace, taken out of the furnace, and preliminarily sintered by immediate pressurization for forging. The heating temp. is higher than the m.p. of Sn, much lower than the m.p. of Cu, and lower than the sintering temp. Accordingly, the Sn is melted without sintering and acts as a binder, and the bulk mixture is made almost equal to an end product in size. The preliminarily sintered body is then sintered at a temp. slightly lower than the m.p. of Cu in dies while applying a pressure to obtain a fiber-reinforced metal.

Abstract: PURPOSE:To manufacture a fiber-reinforced metallic material of superior strength by covering a reinforcing fiber with a metal or an alloy as a matrix and discharge- sintering an aggregate of this covered fiber under press. CONSTITUTION:The surface of an inorg. fiber of high strength and high elasticity such as carbon fiber, alumina fiber and silicon carbide fiber, esp. carbon fiber is covered with a metal such as Cu, Al or Ni or an alloy thereof in a thickness of about 1-3mu by plating, spraying, vacuum deposition or other method. This covered reinforcing fiber is cut into suitable lengths and filled in graphite dies provided with upper and lower electrodes. By applying a pulse voltage to the electrodes discharge is generated in minute gaps in the dies to scatter surface oxide films with discharge energy. A current concentrically flows to the film-free portions to generate Joule heat, and the covering metal diffuses each other. The cut covered fibers are then unified under a press. of several hundreds kg/cm to reinforce the covering metal as a matrix. Thus, a fiber-reinforced metallic material is obtd.
