As described in Section III) entitled, methods for producing fiber-reinforced metal composite materials in which the reinforcing fibers are continuous fibers include ■diffusion bonding method, ■plasma spray method, and ■vapor phase t.
There are li deposition method, ■melt infiltration method, ■electrodeposition method (plating method), etc.As methods for manufacturing fiber reinforced metal composite materials whose reinforcing fibers are discontinuous fibers, ■powder metallurgy method, ■compocasting method, ■ It is known that there are methods such as molten metal forging method, ① melt processing method, ① HIP method, etc.

複合材料の製造が高コストになり、このことか複合材料
の実用化に対する一つの大きな阻害要因となっている。Among these methods, the melt infiltration method and the molten metal forging method are superior to the other methods mentioned above in terms of mass productivity, and therefore these methods have been generally employed industrially. However, in the melt infiltration method and the molten metal forging method, it is necessary to pressurize the molten matrix metal to a very high pressure, which requires large-scale manufacturing equipment, which makes the manufacturing of composite materials expensive. This is one of the major hindrances to the practical application of composite materials.

要である。Thus, in the production of composite materials by the melt infiltration method or the molten metal forging method, the wettability of the reinforcing fibers with the molten matrix metal is important in order to reduce the necessary pressure applied to the molten matrix metal, and furthermore to omit the application of pressure. It is necessary to significantly improve the

いう問題がある。In view of this demand, for example, Japanese Patent Laid-Open No. 61-295344 proposes the use of an aluminum alloy to which a special element is added as a matrix metal. However, there is a problem in that sufficient wettability cannot be ensured simply by adding a special element to the matrix metal, and the composition of the matrix metal is limited to a specific one.

材料を製造することが困難である。As described in these publications, when the reinforcing fibers are continuous fibers, the fibers are generally oriented in one direction, so that the molten matrix metal penetrates between the individual continuous fibers due to capillary action. Accordingly, the method described above can improve the wettability between the fibers and the molten 7-trix metal. However, when reinforcing fibers that have poor wettability with the molten matrix metal are used, it is difficult to sufficiently improve the wettability with the molten matrix metal even with these methods. Therefore, it is difficult to produce a composite material with excellent adhesion between reinforcing fibers and matrix metal.

る。Furthermore, when the reinforcing fibers are short fibers or whiskers, since they are discontinuous, penetration of the molten matrix metal by capillary action cannot be expected. means for improving the wettability of continuous fibers, as described in
Merely applying the known methods to short fibers and whiskers cannot sufficiently improve their wettability. Furthermore, when the reinforcing fibers are short fibers or whiskers, it is difficult to cover them with a large amount of metal or apply a large amount of metal powder, and the cost is extremely high. These problems also occur when the surface of the fiber is coated with a metal oxide as described in US Pat. No. 4,376,803 and US Pat. No. 4,569,886.

As described in '131466 and JP-A-62767133, there is a known method in which a reinforcing material molded body is preheated to a predetermined temperature and then a molten matrix metal is infiltrated into the molded body under pressure. There is. According to this method, the wettability of the matrix metal with the molten metal is improved by heating the reinforcing material itself to a temperature at which the reinforcing material itself is heated, and the permeability of the matrix metal with the molten metal is improved compared to the case where the molded body is not preheated. . However, in these methods, it is essential to preheat the molded body, and special means are required for that purpose, so these methods also have limitations in streamlining and reducing the cost of manufacturing composite materials. There is.

。In addition, Japanese Patent Application Laid-open No. 6, filed by the same applicant as the applicant
As described in Japanese Patent No. 1-1.65265, reinforcement is achieved by utilizing an oxidation-reduction reaction between a metal oxide contained in a molded product of a reinforcing material and a specific metal element in a matrix metal. A method of improving the permeability of molten matrix metal into a material molded body is known. However, this method has a problem in that it is not possible to produce a composite material in which the matrix metal is a metal of an arbitrary composition because the elements that undergo redox reactions with each other are limited.

ないという問題かある。Furthermore, in any of the above-mentioned conventional methods, it is essential to pressurize the molten matrix metal to a relatively high pressure, and therefore, in these conventional methods, pressurization of the molten matrix metal is omitted. It is not possible to efficiently and inexpensively produce compound feed by omitting the use of molds, etc. required for pressurization, and a relatively large amount of 7Tx is produced in areas other than the molded product in the mold each time it is cast. The problem is that the yield cannot be improved because the metal inevitably solidifies.

5science Letters describes a method for producing a composite feed in which a reinforcing fiber molded body is pretreated with a fluorine-containing reagent and the molded body is impregnated with a molten matrix metal. However, this method is limited to reinforcing fibers that are mainly composed of carbon or carbide or whose surfaces are coated with carbon or carbide, and the processed molded body is not used before being impregnated with the molten matrix metal. The problem is that it needs to be preheated.

できる。Therefore, according to the h° method of the present invention, there is no need to pressurize the molten matrix metal or preheat the reinforcement to a high temperature, and therefore there is no need to pressurize the molten matrix metal or preheat the reinforcement to a high temperature. Composite abrasive materials in which matrix metal is well filled between individual reinforcing materials can be produced more efficiently and at lower cost than conventional methods without requiring any equipment.

きる。Further, according to the present invention, the reinforcing material molded body is introduced into the molten matrix metal through the layer of the molten flux, so that at least in the initial stage, the reinforcing material is introduced into the molten metal in the layer of the molten flux. It is in a covered state. Therefore, compared to the conventional method in which no flux melt is used, the deterioration caused by the reaction of the reinforcing material with the molten 7-trix metal is prevented or reduced, and the 7-trix metal is thereby successfully compositely strengthened. Compound feed can be produced.

できる。Furthermore, according to the method of the present invention, as mentioned above, the molten metal of the matrix metal can penetrate well into the reinforcing material molded body.
If a molded body with a predetermined volume ratio is formed with a reinforcing material in a predetermined shape and size, and the molded body is immersed in a molten matrix metal and then taken out from the molten metal, the molten matrix metal will overflow over the entire molded body. It penetrates quickly and completely, thereby forming a composite abrasive material of substantially a predetermined shape and size with a predetermined reinforcement volume ratio. Therefore, a mold is required to pressurize the molten matrix metal and define a predetermined product shape, and a large amount of the matrix metal inevitably solidifies in parts of the mold other than the composite material. Compared to the forging method, etc., it is possible to efficiently produce a composite feed having a substantially predetermined shape and size at a very high yield in a low-lying manner.
