The invention relates to a preparation method for a laminated aluminum matrix composite material without residual pyrolytic carbon. The preparation method for the laminated aluminum matrix composite material without residual pyrolytic carbon disclosed by the invention aims at solving the problems that in an existing laminated aluminum matrix composite material preparation process, a thickness control method is complex, thickness control is inaccurate, cost is high, interface combination performance of the laminated composition material is weak, a prefabricated body is prone to collapsing in acomposite material preparation process, and the prepared laminated aluminum matrix composite material has residual pyrolytic carbon. The preparation method comprises the steps: 1, weighing materials;2, preparing SiC slurry; 3, tape casting SiC nanowire raw sheets; 4, preparing the prefabricated body; 5, degreasing, preheating and removing residual pyrolytic carbon; 6, impregnating molten aluminum. According to the preparation method disclosed by the invention, oxidizing and removing the pyrolytic carbon is achieved, preheating time is shortened, the thickness control method is simple, the thickness is accurate, a technology is simple, aluminum foils can separate SiC nanowire layers and further can ensure integrity of a laminated structure of the composite material, and interface combination of the composite material is excellent.
