The lauan wood is used as a template to prepare Al/C and Al/ composites. Porous carbon is first pyrolyzed from the wood template. The final composites having wood structure are obtained by injecting aluminum alloy and silicone resin into the porous carbon. The microstructures, thermal expansions, and thermal conductivity of these products are analyzed by the scanning microscope, dilatometer, and conductometer. The model of thermal conduction is established.
