Abstract
Disclosed herein is a method for producing a thin sheet of an Al--SiC composite material, which comprises the steps of: mixing aluminum powders and SiC powders to give spraying powders; and plasma-spraying the spraying powders on a graphite substrate to form a thin sheet. According to the method of the present invention, the composite material having low thermal expansion coefficient, high thermal conductivity and low density, which is suitable for use as a thermal management material for electronic devices, can be produced by a simple production process.
