1. A manufacturing method of composite sintering materials using carbon nanotube comprising the steps of:

  • manufacturing master alloys by combining carbon nanotubes with metal powders;

    growing or alloying the carbon nanotubes by compacting and then sintering the master alloy;

    generating the carbon nanotubes (including carbide nano particles) in the pores of a sintered product or impregnating and combining the carbon nanotubes therein; and

    strengthening mechanical characteristics by repeatedly performing the sintering process and the generating process of the carbon nanotubes in the sintered product or the impregnating and combining processes of the carbon nanotubes.
