A fiber-reinforced composite material, that is, a metal matrix composite material, has been developed in which a reinforcing fiber molded body having a metal or alloy as a matrix metal such as pure aluminum is combined with a reinforcing material preform having fibers such as carbon, alumina, and silicon carbide. There is.

周囲の空気が同時に金型１０に送り込まれてしまい満足
な結果が得られない。(Problems to be Solved by the Invention) In such manufacturing, - During boat fishing, air remains on the surface of the reinforcing material preform 11, so when pressurizing the molten metal 12 and the reinforcing material preform 11, This air stays on the sides of the reinforcing material preform 11, resulting in uncompounded portions 14 where compounding cannot be performed. This uncomposited portion] 4 reduces the specific strength and specific rigidity of the molten metal 12 and the reinforcing material preform 11, making it impossible to obtain a high-quality metal matrix composite material. Therefore, the inside of the mold 10 is made vacuum or low pressure,
A method of removing air remaining in the reinforcing material preform 11 is adopted, but this method does not provide a satisfactory result because surrounding air is simultaneously sent into the mold 10 when the molten metal 12 is injected.

いような方法が取られている。Instead, as shown in FIG. 6, an air vent hole 16 having an air vent 15 is provided at the bottom, and the air remaining in the reinforcing material preform 11 etc. under pressure is removed through the air vent 15 and the air vent hole 16. Methods are being taken to ensure that no uncompounded parts are produced by releasing it into the atmosphere.

生産には適さない等の問題があった。Although this method can eliminate the generation of uncompounded parts to some extent,
If pressurization is performed several times, it becomes impossible to insert the molten metal into the air vent 15 or air vent hole 16 and use it repeatedly. Therefore, it is often necessary to remove the molten metal 12 from the air vents 15 and air vents 6 during the work, which poses problems such as the work is time-consuming and unsuitable for large-scale industrial production.
本発明は、上記問題を解決すべくなされたものであって

ものである。(Means for Solving the Problems) The present invention involves arranging a reinforcing material preform in a mold, injecting a molten metal such as aluminum into the mold, and then forming a reinforcing preform and a molten metal such as aluminum. An air pocket is formed in the inner wall of the mold at a position close to the reinforcing material preform, and a porous heat-resistant material is removably attached to this air pocket. This is what I did.

The molten metal is pressurized by a pressure punch. Due to this pressurization, air remaining in the reinforcing material preform etc. is moved to the porous heat-resistant material. Therefore, no air remains in the reinforcing material preform, and the formation of uncompounded parts in the metal matrix composite material of the reinforcing material preform and the molten metal is prevented.

A reinforcing material preform 11 heated to 00° C. is placed. A molten metal 12 of aluminum or the like at 700° C. is pumped into the mold 20 from a molten metal tank (not shown) by a ladle 26 (see FIG. 2). A pressure punch 13 is inserted into the mold 20, and the reinforcing material preform 11 and the molten metal 12 are pressurized at a pressure of, for example, 1000 atmospheres (
(See Figure 3). Due to this pressurization, the molten metal 12 penetrates into the structure of the reinforcing material preform 11, and the metal matrix composite moon 27 is manufactured. Air that remains on the surface of the reinforcing material preform 11 during the pressurization is removed from the porous heat-resistant material 25 such as ceramics or firebrick.
