CARBON NANOTUBE COMPOSITE AND METHOD FOR MANUFACTURING THE SAME

摘要

This invention provides a carbon nanotube composite manufactured by compositing a carbon nanotube with a metal without heating, and a method for manufacturing the same. The carbon nanotube composite is manufactured by monoaxially pressing a powder mixture of a metallic powder with a carbon nanotube using first and second molds and allowing a strain stress to act on the powder mixture being pressed in a nonheated state, that is, without externally applying heat to the powder mixture to integrally bind the metallic powder and the carbon nanotube to each other. In this case, before the application of a strain stress to the powder mixture, the powder mixture is maintained in such a state that the powder mixture is pressed at a predetermined pressure or higher for a predetermined period of time, thereby eliminating air present in the powder mixture. The strain stress which acts on the powder mixture is smaller than the threshold strain stress by which the cylindrical shape of the carbon nanotube is broken.
