される。An example of a process diagram for producing the metal composite of the present invention is shown in FIG. As shown in FIG. 1 (a), a pre-heated mold 2 for molten metal forging is provided with (1) ceramic fibers, carbon fibers, ceramic whiskers, ceramic particles or carbon particles and (2) titanium metal powder. The formed preform 1 is mounted at a predetermined position. Then, a molten aluminum alloy is poured. The preform 1 and the mold 2 are preferably preheated, and the preheating improves the fluidity of the aluminum alloy, so that the preform 1 can be smoothly impregnated. The temperature of the molten aluminum alloy itself is preferably 50 to 450 ° C. higher than its melting point in order to facilitate impregnation into the preform 1. Next, as shown in FIG. 1B, the punch 3 is set in the mold 2 and pressure is applied. The pressure is preferably 10 to 100 MPa so that the molten metal is sufficiently impregnated in the preform and the effect of crystal refining is obtained, and this pressure is preferably applied until the molten metal is completely solidified. Then, as shown in FIG. 1 (c) or (d), a forging material is obtained in which the metal composite body 4 in which the preform is impregnated with the aluminum alloy and the solidified molten metal 5 are integrally bonded,
It is taken out from the mold 2 by a knockout pin 6 arranged at the bottom of the mold 2 as shown in FIGS. The metal composite 4 of this forging material is HB20.
Although the hardness is about 0, it is not at a desired level as a sliding material for brakes or a heat resistant bearing material as it is. Next, the taken out forging material is cut into a brake rotor 7 as shown in FIG. 1 (e), or cut into a bearing 8 as shown in FIG. 1 (f).
