  • Method for preparing aluminum carbon composite by using foam aluminum
    Patent number: 11878341
    Abstract: A method for preparing an aluminum carbon composite by using a foam aluminum includes the following steps. Electromagnetic stirring and drying are performed on the foam aluminum and a carbon material to obtain a foam aluminum preform; an aluminum block is melted into aluminum liquid, the aluminum liquid is adjusted to qualified aluminum liquid, the qualified aluminum liquid is cooled to a temperature of 620˜650° C. and keeping the temperature to make the qualified liquid aluminum become a semi-solid state, then the foam aluminum preform is pressed into the qualified liquid aluminum and performing electromagnetic stirring. A mold is heated to a certain temperature and extrusion molding is performed to obtain a carbon reinforced aluminum matrix composite material. The method overcomes a problem that the carbon material and the aluminum matrix have poor wettability and are not easy to be added into the aluminum matrix.
