Abstract
The heat conductivity of an aluminum composite material containing a fibrous carbon material is enhanced. In order to realize this, a spark plasma sintered body having a fibrous carbon material compounded in a metal matrix powder of aluminum or the like is fabricated. At the time of fabrication, an aluminum powder serving as a matrix mother material is compounded with an Al alloy powder such as an Al-12Si powder having a melting point lower than the sintering temperature of the mother material. During the process of sintering the aluminum powder, the Al alloy powder is melted, whereby the heat conductivity between the aluminum powder particles and between the aluminum powder particle and the fibrous carbon material is improved.
