Three-layer aluminum composite with 10vol.%SiC-Al composite+3vol.%SiC-Al composite+3col.%CF/Al composite was fabricated by stacking and sintering mixed Al powder containing SiC particles, CF and Al powders. The composites were also hot-rolled, and the CF was oriented in the rolling direction. The three-layer composites after rolling have high strength and high ductility. The thermal conductivity was also high in the rolling direction. The three-layer composites were slightly inferior to the CF/Al composites but were comparable to a single Al block. It shows that the three-layer composites allows the production of a material with high strength and ductility while maintaining thermal conductivity.
