The invention discloses a preparing method of a cluster type (SiCp/Al)/Al composite, and relates to preparing methods of composites. The method aims at solving the problems that an SiCp/Al composite prepared through an existing method is poor in plasticity and toughness and high in preparing cost, and in the preparing process of the SiCp/Al composite of a cluster structure, the breaking efficiencyof the composite is low. The method comprises the steps of firstly, composite waste cleaning, drying and screening; secondly, composite powder liquid nitrogen ball milling; thirdly, prefab cold pressing preparing; fourthly, mold preheating and aluminum metal melting; fifthly, liquid aluminum infiltration and sixthly, hot extrusion. The method has the beneficial effects that the composite preparedthrough the method is the cluster composite, compactness is high, tensile strength and plasticity are good, cost is low, the process difficulty is low, and microstructure design of the material is easily achieved. The method
