The working temperature of the fan blade of the engine is the environmental temperature, the titanium alloy and resin-based composite material which are designed in a hollow mode are mainly adopted at present, but the application of the fan blade of the engine is limited due to the defects of high preparation difficulty, long period and high cost, and the preparation period and the cost can be reduced by adopting the aluminum-based composite material to prepare the fan blade of the aero-engine.
The traditional ceramic particle reinforced aluminum matrix composite material takes ceramic particles as a reinforcing phase and aluminum alloy as a matrix, and the aluminum matrix composite material prepared by the method has low density, high specific strength, excellent wear resistance and good high temperature resistance; however, the method has certain defects that the wettability of the ceramic particles and the matrix is poor, the interface reaction is difficult to control, and the ceramic particles are difficult to disperse uniformly, so that the reinforcing effect of the ceramic particles is weakened.
CN103725911A proposes a preparation method of alumina particle reinforced aluminum matrix composite, which is prepared by uniformly mixing alumina ceramic particles with aluminum powder, and carrying out hot pressing and hot processing, wherein the mechanical properties of the alumina particle reinforced aluminum matrix composite are not outstanding due to weak interface combination of the ceramic particles and the matrix.

The ceramic particles and the aluminum alloy powder are particles with the same grade of particle size, and the interface bonding strength between the ceramic particle reinforcing phase and the matrix is still not ideal.

At present, the strength of the aluminum alloy is not enough when being applied to the field of aerospace, and the aluminum-based composite material with lower density and higher strength can be prepared by compounding an aluminum alloy matrix with reinforcing phases with different structures such as graphene, carbon nano tubes, chopped fiber yarns and continuous fibers. The existing preparation methods of the aluminum-based composite material mainly comprise a stirring casting method, a powder metallurgy method, a melt infiltration method and the like, and various preparation methods have the advantages and the disadvantages. By compounding multiple reinforcing phases into the aluminum alloy matrix, the aluminum matrix composite with high cost performance can be prepared by exerting different reinforcing mechanisms.
