Claims
- 1. A method of producing a machine part of a fiber-reinforced composite material, said method comprising forming a fibrous shaped body by effecting a partial diffusion-bonding of a plurality of metallic fibers by copper solder; said fibrous shaped body having a bulk density of more than 2.0 and up to 5.0 g/cc and forming a mechanical part of fiber-reinforced composite material by integrating the fibrous shaped body with a matrix by high-pressure solidification.
- 2. A method as claimed in claim 1, wherein said forming of the fibrous shaped body comprises placing said metallic fibers in a heat-resistant shaping mold together with the copper solder at a predetermined bulk density; and heating the shaping mold to cause said copper solder to impregnate fine spaces between adjacent fibers by capillary action.
- 3. A method as claimed in claim 2 wherein said shaping mold has an atmosphere consisting of a reducing gas, an inert gas or a vacuum.
- 4. A method as claimed in claim 1 wherein said metallic fibers comprise stainless steel.
- 5. A method as claimed in claim 1 wherein said copper solder consists of copper wires.
- 6. A method as claimed in claim 2 wherein said fibers are in a bundle and are of polygon cross-section with a mean diameter of about 30.mu. and said copper solder is in the form of copper wires disposed centrally in said bundle and having a diameter of about 0.2 mm.
- 7. A self-supporting fibrous shaped body adapted for forming a reinforcement in a non-copper matrix metal under high-pressure solidification, said fibrous shaped body comprising a plurality of metallic fibers at least partially diffusion-bonded by copper solder substantially over the entire extent of the shaped body.
- 8. A fibrous shaped body as claimed in claim 7 wherein said metallic fibers include stainless steel fibers.
- 9. A machine part comprising a non-copper matrix metal and a fibrous shaped reinforcing body integrated in said matrix metal, said fibrous shaped reinforcing body comprising a plurality of metallic fibers at least partially diffusion-bonded by copper solder over substantially the entire extent of said body, said fibrous shaped reinforcing body having a bulk density of more than 2.0 and up to 5.0 g/cc.
- 10. A machine part as claimed in claim 9 wherein said fibrous shaped reinforcing body is integrated in said matrix metal by high-pressure solidification casting.
- 11. A self-supporting fibrous shaped body adapted for forming a reinforcement in a non-copper matrix metal under high-pressure solidification, said fibrous shaped body comprising a plurality of metallic fibers at least partially diffusion-bonded by copper solder substantially over the entire extent of the shaped body, said fibrous shaped body having a bulk density of more than 2.0 and up to 5.0 g/cc.
