Metal material and method of producing the same, and carbon fiber-metal composite material and method of producing the same

摘要

A method of producing a metal material in which carbon nanofibers are dispersed around metal particles includes: (a) mixing an elastomer which includes an unsaturated bond or a group having affinity to the carbon nanofibers, the metal particles, and the carbon nanofibers, and dispersing the carbon nanofibers by applying a shear force to obtain a carbon fiber composite material; and (b) heat-treating the carbon fiber composite material to vaporize the elastomer in the carbon fiber composite material.
