The invention provides a preparation method for enhancing the toughness of an aluminum-based composite material. According to the method, a small-size metal reinforced particle reinforced aluminum matrix composite blank is prepared through a hot pressing sintering method, then metal reinforced particles are fully diffused into an aluminum matrix through a full heat treatment method, and due to the fact that the blank is small in size and the hot pressing sintering preparation method is adopted, the metal reinforced particles are fully dispersed into the aluminum matrix. And the metal reinforced particles can be fully diffused in the aluminum matrix. And then the small-size aluminum-based composite material is used as a genetic material, and the large-size aluminum-based composite material is formed by adopting a smelting method. In the smelting and solidification process, the diffusion sufficiency and uniformity of the metal reinforced particles can be inherited to the aluminum-based composite prepared throug
