woods metal matrix composites microstructures thermal conductivity thermal expansion thermal conduction models
To research new composite materials,the plant structure is applied to the metal matrix composites preparation.The lauan wood is used as a template to prepare Al/C and Al/(SiC+C) 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.The results indicate that the structure of the composite is determined by the natural structure of the template selected.This is different from the traditional metal matrix composites with their structures obtained artificially.The composites exhibit a lower coefficient of thermal expansion than aluminum and a higher thermal conductivity(98.2 and 95.4 W·m-1·K-1) than porous carbon(2.22 W·m-1·K-1).
