摘要： A method of producing an aluminum matrix composite material is described that comprises the steps of: mixing an aluminum powder and a ceramic powder to prepare a mixed powder; providing a lower casing made of aluminum and formed in a hollow rectangular parallelepiped shape having an open top, and a closing member made of aluminum and formed in a shape adapted to hermetically close the open top of the lower casing; packing the mixed powder into the lower casing; closing the open top of the lower casing filled with the mixed powder, by the closing member, to prepare a pre-rolling assembly having the mixed powder hermetically sealed therein; preheating the pre-rolling assembly; and rolling the preheated assembly to obtain the aluminum matrix composite material, where the aluminum matrix composite material includes a pair of metal plates having the mixed powder therebetween.
