METHOD FOR MANUFACTURING COMPLEX WIRE RODS FOR A POWER SUPPLY BY USING ALUMINUM AND CARBON NANOTUBES AND A PRODUCT MANUFACTURED WITH THE SAME TO MEET THE PHYSICAL AND MECHANICAL PROPERTY NEEDS OF A POWER SUPPLY WIRE

摘要

PURPOSE: A method for manufacturing complex wire rods for a power supply by using Al(aluminum) and CNT(carbon nanotubes) and a product manufactured with the same are provided to manufacture complex wire rods with simple equipment and reduced carbon emissions.;CONSTITUTION: A method for manufacturing complex wire rods for a power supply by using Al and CNT comprises the steps of: mixing a power mixture comprising 0.2-30 wt.% of CNT and 99.8-70 wt.% of Al powder with a dispersion inducing agent at a volume ratio of 1:1 and irradiating the same with ultrasonic waves for 10-15 minutes to produce a dispersed mixture(100); heat-treating the dispersed mixture in an inert atmosphere at 400-500°C for 1-2 hours to completely remove the dispersion inducing agent and to obtain Al-CNT mixed powder(200); making the Al-CNT mixed powder into a bulk-type sintered body by using a spark plasma sintering machine(300); and extruding the sintered body through a hot extruder to obtain complex Al-CNT wire rods(400).;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Natural rubber; (BB) Al powder; (CC) Al-CNT powder; (DD) Pressure; (EE) Sintered body
