N2 - Based on the bionic Bouligand structure, a spiral composite-metal (FRP-Metal) hybrid structure with layered embedded "cross" mesh wire was constructed, and its structural damage and energy absorption characteristics under impact load were analyzed. The results show that the FRP-Metal composite structure with "cross" mesh wire can greatly increase the energy absorption uniformity of the structure and improve the material utilization rate of the structure. On the maximum deflection of deformation, compared with the FRP-B structure without wires, the "cross-shaped" mesh wires reduce the maximum deformation of the whole structure and improve the overall stiffness of the structure. Furthermore, the composites-superelastic shape memory alloy, composites-lightweight aluminum and composites-conventional steel (FRP-SMA, FRP-A12024 and FRP-Q235) are compared and analyzed. FRP-A12024 has lighter structure and higher stiffness, its specific energy absorption is 38. 9% higher than that of FRP-Q235, and its maximum deformation is 11. 95% smaller than that of FRP-Q235. FRP-SMA has higher energy absorption uniformity among layers, and the variance of energy absorption ratio of each layer is 47. 12% smaller than that of FRP-Q235.
