The invention relates to a method for preparing a cluster-like aluminum based composite material, in particular to a method for preparing the cluster-like aluminum based composite material by using arecycled SiCp/Al composite material in order to solve the problems that the plasticity and toughness of an SiCp/Al composite material prepared through an existing method are poor, and the recycling difficulty of the SiCp/Al composite material is high. The method includes the steps that firstly, the waste composite material is cleaned, dried and screened; secondly, the composite material powder issubjected to ball milling; thirdly, a prefab is prepared in a cold pressing mode; fourthly, a mold is preheated, and aluminum metal is melted; and fifthly, infiltration of molten aluminum is carried out. The method has the beneficial effects that the composite material prepared in the invention is the cluster-like composite material, and is high in compactness, good in tensile strength and plasticity, low in cost and low in technical difficulty, and the microstructure design of the material is easy to achieve. The method is suitable for preparing the cluster-like aluminum based composite material.
