The invention relates to a novel multi-level composite material buffering and energy-absorbing device which is formed by assembling a plurality of N-level energy-absorbing structures in a face-to-face contact mode and nesting a composite material shell outside the N-level energy-absorbing structures, and the level N of the energy-absorbing structures is larger than or equal to 3. Wherein the N-stage energy absorption structure is formed by assembling a plurality of (N-1)-stage energy absorption structures in a face-to-face contact mode and nesting a composite material shell outside the (N-1)-stage energy absorption structures, and the (N-1)-stage energy absorption structure is formed by assembling a plurality of (N-2)-stage energy absorption structures in a face-to-face contact mode and nesting a composite material shell outside the (N-2)-stage energy absorption structures. And the steps are cyclically and repeatedly nested in sequence until the first-stage energy absorption structure is assembled by a plurality of zero-stage energy absorption structures in a surface-to-surface contact manner, and a composite material shell is nested outside the first-stage energy absorption structure. The device has the advantages of being high in deformation coordination and guidance, large in specific energy absorption, good in impact resistance, simple in production process, low in production cost, light in weight, flexible in design scheme and the like.
