[0003] However, the network-reinforced metal matrix composite material is a new material that has just been developed in the past ten years. This type of material subverts the concept of uniform distribution of the reinforcement phase in the traditional metal matrix composite material, making the reinforcement phase distributed in a spatial network. The theoretical upper limit of composite stiffness in the form of network distribution in the reinforcement phase space, the reinforcement effect of the reinforcement phase is optimized, and the microstructure of the material is more complex with the improvement of performance
