Abstract
A method of manufacturing a metal-carbon nanocomposite material in which aluminum is used as the matrix is disclosed. The manufacturing method comprises mixing a Si-coated carbon nanomaterial (30) and a powdered Mg material (33), heating the mixture to a melting point of the Mg material or higher, and thereafter cooling the mixture to obtain an Mg-carbon nanomaterial (34). A metal-carbon nanomaterial in which Al is used as the matrix is provided by cooling the Mg-carbon nanomaterial and molten Al (40) in a mixed state.

A method for manufacturing a metal-carbon nanocomposite material, comprising the steps of:
- preparing an Si-coated carbon nanomaterial by depositing Si microparticles on a surface of a carbon nanomaterial;
- obtaining an Mg-carbon nanomaterial by mixing the Si-coated carbon nanomaterial with one of a powdered Mg material and a liquid Mg material, and when the powdered Mg material is mixed, cooling the mixture after the latter is held a predetermined interval of time in a state of being heated to a melting temperature of the powdered Mg material or higher;
- and
- introducing the Mg-carbon nanomaterial into molten Al and cooling a resulted mixture after a predetermined interval of time to thereby obtain a metal-carbon nanocomposite material in which Al is used as a matrix.
