The invention discloses a fiber-metal hybrid laminate of a reverse honeycomb sandwich structure and a preparation method. The fiber-metal hybrid laminate is an advanced material supply technology obtained by performing multi-dimensional optimization combination on material structure design, a light alloy precision machining technology, a surface engineering technology and a heterogeneous composite material preparation technology. The method comprises the following steps: firstly, cutting a concave polygonal structure according to a design track by utilizing a subtractive machining technology, and closing an upper layer plate and a lower layer plate to form a concave reverse honeycomb sandwich structure; then, the machined surface of the metal laminate is subjected to chemical treatment to be passivated, and the purpose is to increase the bonding force between the fiber layer and the metal layer; then, the concave structure of the metal layer is filled with a viscous mixture, and the multifunctional characteristic and the impact resistance characteristic of the composite laminate are guaranteed; then, the fiber prepreg is laid between the upper layer metal plate and the lower layer metal plate, and a prefabricated fiber-metal hybrid laminate is obtained; and finally, performing hot-pressing curing treatment on the prefabricated mixed laminate through a vacuum bag-autoclave system to obtain the applicable composite laminate.
