[Prior art] ' The conventional method for manufacturing intermediate materials such as metal-based composite materials is to lay a matrix metal foil on a mandrel a, and then wind reinforced 1111tC on top of it at a constant pitch, as shown in Figure 4. This reinforced mmc is generally bonded to the matrix metal foil using a resin such as acrylic or polyester.

The metal-based composite material is laminated in the shape of the part to be manufactured, sealed in a bar made of stainless steel or the like as shown in FIG. 7, heated to an appropriate temperature, and bonded and formed by applying pressure using a press or the like. When the metal composite material is green tape e,
A large amount of adhesive d is required to adhere the reinforced muC to the matrix metal foil, but as shown in Fig. 7, the adhesive d is removed during heating in the bag h. As shown in j, the inside of the bag h is suctioned with a vacuum pump, and the holding time in this state is, for example, 2 hours at 500°C, which is recommended as the removal cycle for the adhesive d, which causes a long manufacturing time. .

Further, when the metal-based composite material r1 is a thermal spray tape q shown in FIG. 6, the cost of a thermal spraying apparatus for the matrix metal r is relatively high. Furthermore, in plasma spraying, etc., the plasma flame is extremely high temperature of several thousand degrees or more, and at least from the point where the metal is melted and sprayed, the reinforced mmc may be overheated and deteriorated, or due to thermal expansion of the mandrel a (see Figure 4). The reinforced mmc may be subjected to tensile stress exceeding the allowable value and deteriorated. Further, while the matrix metal f is about to fly, an oxidized layer is formed on its surface, and this oxidized layer may significantly reduce the properties and formability of the matrix metal f. In thermal spray tape g, especially when reinforcing fiber assembly C with a diameter exceeding 0.1 mm is used, the stiffness of the reinforcing fiber C itself is high, and it is difficult to directly mold parts with curved surfaces using thermal spray tape g. Moreover, the yield of matrix gold ff1f (the amount of metal deposited as an intermediate material/supplied to the thermal spray) is low, generally 50 to 80%.

If foil is not used, the surface of the mandrel should be precision-finished to a smooth surface.

After the reinforced TFTAM 4 is wound around a mandrel, slurry 3 is sprayed 5 onto the reinforced fibers 4 wound around the mandrel using a spray gun widely used for painting and the like. By doing this, as shown in Figure 3, the reinforcing fibers N4 and the metal powder 1 are lined up three-dimensionally and are fixed by the adhesive, so compared to the conventional green tape e. , the amount of adhesive required is one-third to one-fourth. This facilitates the removal of the solvent and does not necessarily require a special removal heating cycle.
