この発明は、繊維強化複合材料の製造方法に関し、特に

を用いて焼成する繊維強化複合材料の製造方法に関する
。Detailed Description of the Invention [Industrial Application Field] The present invention relates to a method for producing a fiber-reinforced composite material, and particularly to a fiber-reinforced composite material in which a fiber-reinforced composite material having a three-dimensional shape is fired using a hot press. Relating to a manufacturing method.
［従来の技術］
従来、繊維強化複合材料は主として気相化学蒸着法（以

。[Prior Art] Conventionally, fiber-reinforced composite materials have been mainly produced by vapor phase chemical vapor deposition (hereinafter referred to as CVD) and liquid phase impregnation. The CVD method is a method in which a hydrocarbon gas is brought into contact with a fiber base material heated to a high temperature under reduced pressure to deposit carbon atoms on the base material, and the liquid phase impregnation method is a method in which a fiber base material is heated with a liquid resin or molten pitch. Impregnated with matrix material such as and carbonized and fired.
ＣＶＤ法および液相含浸法により繊維強化複合材料を製

。When manufacturing fiber-reinforced composite materials using the CVD method and liquid phase impregnation method, the density is high near the surface of the base material, but the density is low at the center of the thickness of the base material because it is difficult for both the gas and liquid phases to enter. Become. As the strength decreases as the density decreases, as a countermeasure for this, the CVD method removes the deposits that adhere to the surface of the substrate during manufacturing, making it as easy as possible for the gas phase to penetrate, and increasing the density in the center of the thickness of the substrate. We are trying to make this happen. Furthermore, in the liquid phase impregnation method, the carbonization yield is improved by repeating the impregnation and firing steps, thereby increasing the density at the center of the thickness of the base material.
このように、ＣＶＤ法および液相含浸法では、製造工程
が複雑であり、製造期間が非常に長くなるという欠点が
あり、製造コストの削減が行ないない問題点があった。As described above, the CVD method and the liquid phase impregnation method have disadvantages in that the manufacturing process is complicated and the manufacturing period is extremely long, and the manufacturing cost cannot be reduced.
そこで、最近、ホットプレスを用いる簡便な製造方法が
提案されている。これらは、たとえば、特開昭６１−２

きるものである。Therefore, recently, a simple manufacturing method using hot pressing has been proposed. These are, for example, JP-A-61-2
It was disclosed in 1973. This method involves depositing fine carbon powder and a carrier on a fiber substrate by electrophoresis, drying and heating, and then applying pressure in the stacking direction using a hot press, heating, and firing to easily create a high-density fired body. It is something that can be done.

Referring to FIG. 2, the carbon mold includes a pedestal 1, a carbon mold 2 fitted into the pedestal 1, a carbon jig 3 placed in contact with the pedestal 1, and a carbon mold 2 fitted into the carbon mold 2. and a carbon bunch 10 for applying pressure to the product 4.

A carbon jig 3 manufactured to match the curvature of the inner surface shape of the product 4 is installed on the pedestal 3. A product 4 before firing is placed on a carbon jig 3 so as to be in close contact with each other, and then a carbon mold 2 is installed and a carbon bunch 10 is inserted. The carbon mold thus assembled is placed in a hot press, and the temperature and pressure are adjusted according to the product 4 to fire the fiber-reinforced composite material.

However, in the conventional method, the shapes of the carbon bunch 10 and the carbon jig 3 are formed to match the shape of the product 4 before firing.
The shapes of the carbon bunch 10 and the carbon jig 3 cannot follow the shape of the carbon bunch 10 and the carbon jig 3. As a result, it is not possible to apply a uniform pressure to the entire surface of the product 4 during firing, resulting in the disadvantage that a fired body with a uniform density cannot be obtained.

There is a method using the tatic pressing method. In the HIP method, the product is usually fired at a pressure of 100 to several thousand atmospheres using gas as a pressure medium, so even if the thickness of the product decreases during firing, the pressure on the product remains uniform.

Even if the thickness of the plate decreases, a similar pressure can be applied to the entire surface of the plate, and there is no risk of explosion like with pressurizing methods using gas, so advanced safety measures are not required. Since a high degree of airtightness is not required, expensive equipment is not required.

A carbon jig 3 manufactured to match the curvature of the inner surface shape of the product 4 is installed on the pedestal 3. The product 4 before firing is placed on the carbon jig 3 so as to be in close contact with it, and the carbon mold 2 is attached. The pressure medium 5 is uniformly filled in an appropriate amount, and the carbon bunch 6 is placed in the carbon mold 2.
Insert into. The mold thus assembled is set in a hot press, the temperature and pressure are set according to the product 4, and the fiber-reinforced composite material is fired. Here, the pressure medium is powder, and its material is metal.

That is, when the fiber-reinforced composite material is fiber-reinforced ceramics or fiber-reinforced carbon material, metal cannot be used because it melts, and ceramics are used. Furthermore, the firing temperature is 2000
If the temperature exceeds ℃, even ceramics have problems with heat resistance, so carbon is used.

It is possible to apply uniform pressure to the entire surface of the product 4 by following the change in curvature due to the decrease in the thickness of the product 4 during firing, and
Since the pressure medium is powder, it does not require expensive equipment unlike the HIP method, and pressurization can be performed under conditions close to hydrostatic pressure, making it possible to obtain a high-density and uniform fired body at a low cost.

とがわかる。(Left below) Referring to Table 1, the materials of Example 1 and Example 2 are carbon fiber with self-sintering carbon powder added and SiC.
It can be seen that an average particle size of the pressure medium of 100 to 500 μm is suitable for both the whisker and the SiC powder.

As a result, the pressing force was reduced, and a good product could not be obtained.

上記の結果より、圧力媒体の平均粒径は１００〜５００
μｍが望ましいことがわかる。From the above results, the average particle size of the pressure medium is 100 to 500.
It can be seen that μm is desirable.
