The invention provides a method for preparing a high-strength and high-toughness aluminum-based composite material. According to the preparation method, the ceramic particle reinforced high-entropy alloy composite material is prepared through a synchronous laser cladding technology, then aluminum alloy powder, high-entropy alloy powder and the ceramic particle reinforced high-entropy alloy composite material are mixed, and the high-strength and high-toughness aluminum-based composite material is prepared through hot pressing sintering and pre-deformation treatment. The ceramic particle reinforced high-entropy alloy composite material has the characteristics of a metal material, and the ceramic particle reinforced high-entropy alloy serves as a reinforcing phase and has the advantages of a ceramic particle reinforcing phase and a metal particle reinforcing phase; firstly, the ceramic particle reinforced high-entropy alloy can be well combined with a high-entropy alloy with the same component, and then very goo
