Method for preparing single wall carbon nanotube reinforced metal matrix composite materials using spark plasma sintering process and single wall carbon nanotube reinforced metal matrix composite materials prepared thereby

摘要

The present invention provides a method of preparing a single wall carbon nanotube reinforced metal matrix composite material, the method comprising the steps of: (a) ball milling a metal powder and a single wall carbon nanotube powder to prepare a composite powder; and (b) spark plasma sintering (SPS) the composite powder prepared in the step (a) to prepare a metal-carbon nanotube composite material. The method according to the present invention is capable of easily preparing a bulk type single wall carbon nanotube reinforced metal matrix composite material having excellent physical properties by adding the single wall carbon nanotube powder to various metal matrices, ball milling a mixture of the single wall carbon nanotube powder and the various metal matrices to prepare a composite powder having uniform degree of dispersion, and compounding the prepared composite powder in a short time by using an SPS process in order to manufacture a component made from a material requiring high strength and abrasion resistance.
