Abstract
Carbon nanotube(CNT) possesses excellent electrical, mechanical and thermal properties. Therefore, it has been applied in a variety of fields. In this study, characteristics of composite were investigated after adding CNT into copper, and validity of the extrusion method was reviewed. The CNT and Cu powder are deconcentrated by planetary ball mill. And ratio of CNT is 1 wt%, 5 wt% and 10 wt%, respectively. The ball mill is wet condition with ethanol(20ml) and ZrO2ball(90g). The composite powder was put in a billet (∅= 50mm, length= 100mm) by uniaxial press. Then, after billet heat for 1hr under 880°C, Specimen of round bar was made through extrusion process by universal tester in 200ton capacities.
