てリング溝を形成していた。When manufacturing a fiber composite metal material by casting a fiber molded body, conventionally, the shape of the fiber molded body has not been sufficiently considered, and a simple rectangular parallelepiped or cylindrical shape has been used. For example, when manufacturing pistons, a simple ring-shaped fiber molded body with a rectangular cross section is used. Conventionally, such a fiber molded body is set in a predetermined position in a mold and then cast. , this fiber-reinforced portion was cut to form a ring groove.

問題が参った。However, when the fiber molded body is placed in the mold and pressure cast, the am air of the fiber molded body escapes to the center of the molded body and the part that is in contact with the metal. The problem was that the water circulation was poor and the molten metal did not penetrate easily. In addition, when cutting the fiber-reinforced part, there is a problem that the processing cost for the fiber-reinforced part is large.

。The present invention is intended to solve the above ε problem, and takes into consideration the product shape of the cast-in part of the fiber molded body, so that the melt can sufficiently penetrate into the fiber molded body, and the cutting side processing of the fiber #IA reinforced part can be carried out. The purpose of the present invention is to provide a method for easily producing nine-fiber composite metal materials.

である。The present invention involves forming a fiber molded body according to the shape of the part of the product to be reinforced and after processing [according to the part to be removed], and setting the fiber molded body at a predetermined position on a metal circle. This is a method for manufacturing a fiber composite metal material, which is characterized by casting.

A fiber molded article 1 made of metal fibers and formed into an 8-square shape according to the unusual shape of the part to be reinforced in the product, and an i-shaped cross 1a on the outer periphery according to the part to be #%IJIIj after processing. Manufacture. Next, as shown in FIG. 2, the fiber molded body 1 is formed into $ 1 a and the outer m surface is brought into close contact with the inner box of the metal lid 2, and after setting it in a predetermined position of the metal lid 2, it is placed in the cavity 5. The molded fiber body 1 is filled with a molten metal such as , aluminum, etc., and the molten metal is pressurized to penetrate into the fiber molded body 1 and cast.

For example, when using a conventional fiber molded body 1't- of the same dimensions as 10 cm long x 1 Q wm wide (see Figure 5)
In the case of K6, the penetration of the molten metal was poor in the area surrounded by the 2nd circular image of the metal lid in Figure 3 and the dotted line, but in the case of this example, the center was hollow due to $1aK. Therefore, the molten metal permeates from the outer shell of the fiber molded body 1 toward the center while letting residual air in the fiber molded body 1 escape into the grooves 1a, and thus penetrates throughout the fiber molded body 1.
