Abstract: The present invention relates to a manufacturing method of composite sintering materials using a carbon nanotube comprises the steps of; pressing metal power to obtain a predetermined form, heating the predetermined form in an atmosphere of nitrogen gas for sintering, dipping and heating a sintered product obtained by the sintering process to an organic solution dispersed with a carbon nanotube to combine the carbon nanotube for generating the carbon nanotube, and sintering the sintered product in an atmosphere of nitrogen gas for re-sintering to grow the generated carbon nanotube. The composite sintering materials using carbon nanotubes of the present invention have excellent mechanical, thermal, and electric and electronic characteristics as well as have effects of material cost reduction and manufacturing cost reduction due to reduced sintering temperature.

Abstract: The present invention relates to a manufacturing method of composite sintering materials using a carbon nanotube comprises the steps of; dipping diluted HF solution, natal, or phosphoric acid along with a carbon nanotube solution dispersed to metal power, forming a predetermined form by pressing the master alloys, sintering the predetermined form in an atmosphere of nitrogen gas to grow the carbon nanotube, generating the carbon nanotube in the pores of the predetermined form by inserting ammonia, carbon dioxide carbonated water, acetylene, methane, methanol, or benzene to the sintered product in an inert gas atmosphere of a temperature about 1200° C. to add a toughness; and re-sintering the sintered product in which the carbon nanotube is generated in the atmosphere of nitrogen gas to growth the carbon nanotube.
