Abstract: The present invention provides a method of manufacturing a single-walled-carbon-nanotube-reinforced metal matrix complex material. The method includes (a) manufacturing a complex powder by performing ball milling of a metal powder and a single-walled carbon nanotube powder, and (b) manufacturing a metal-carbon-nanotube complex material by spark-plasma-sintering (SPS) the complex powder manufactured during step (a). According to the method of manufacturing the single-walled-carbon-nanotube-reinforced metal matrix complex material according to the present invention, in order to manufacture material parts requiring high strength and abrasion resistance, the single-walled carbon nanotube powder is added to various metal matrixes and ball milling is performed, thus manufacturing a complex powder having uniform dispersity. The manufactured complex powder is subjected to complexation in a short period of time using a spark-plasma-sintering (SPS) process, thereby easily manufacturing a bulk-type single-walled-carbon-nanotube-reinforced metal matrix complex material having excellent physical properties.
