Abstract:
1. A carbon-containing metal matrix composite material, comprising: graphitized vapor-grown carbon fibers (VGCF) with a metal carbide film formed thereon, wherein the content of said graphitized VGCF with said metal carbide film is substantially between 1 wt % and 40 wt %, and the thermal-conductivity of said graphitized VGCF is substantially between 1000 W/mK and 1980 W/mK; and a metal matrix, wherein said graphitized VGCF are uniformly dispersed in said metal matrix, and the content of said metal matrix is substantially between 60 wt % and 99 wt %; wherein the thermal-conductivity of said carbon-containing metal matrix composite material is between that of metal matrix and graphitized VGCF.
