  • Patent number: 12533872
    Abstract: A fiber-metal laminate having a honeycomb sandwich structure and a preparation method thereof are provided. Firstly, based on material reduction processing technology, a recessed polygonal structure is obtained according to a design trajectory, and an upper layer and a lower layer are closed to form a recessed honeycomb sandwich structure. Then, processed surfaces of the upper layer and the lower layer are chemically treated to passivate the processed surfaces, with the aim of increasing the adhesion between a fiber layer and the metal layers. Then, a viscous mixture is filled into the recessed structures of the metal layers to ensure the multifunctional characteristics and impact resistance of the fiber-metal laminate. Then, a fiber prepreg is laid between the upper layer and the lower layer to obtain a prefabricated fiber-metal laminate. Finally, the prefabricated fiber-metal laminate undergoes thermal curing treatment under pressure in a hot-pressing tank, thereby obtaining the fiber-metal laminate.
