PROBLEM TO BE SOLVED: To obtain an aluminum composite material capable of being easily worked into arbitrary shape by compounding specific amounts of reinforcement consisting of a mixture of carbon nano-tube and carbon nano-capsule with a matrix composed essentially of aluminum. SOLUTION: A carbon rod is subjected to D.C. are discharge in a helium atmosphere, by which cylindrical deposits, consisting of 50-95vol.% carbon nano- tube and 5-30% carbon nano-capsule, are formed on the cathode side. There deposits are added as reinforcement by 5-30vol.% to a matrix composed essentially of aluminum and dispersed sufficiently, and then, plastic working, such as drawing, swaging, and compression forming, is performed at ordinary temp., by which a composite material is formed. By this method, the carbon nano-tube reinforced aluminum composite, material capable of being easily worked into arbitrary shape can be obtained. |
