The honeycomb sandwich structure which is widely used and researched in the field of navigation is different from the natural honeycomb in terms of structure. Research focused on the mechanical performance of natural honeycomb is rarely found. In this paper the 3-D models of the two types are established and the finite elements analysis is implemented to find whether the natural honeycomb is better than the common honeycomb sandwich in some aspects. The deformation and stress of the two types under axial and radial applied forces are found out and then the bionics intelligence of the natural honeycomb is brought to light. The mechanical performance unique to the natural honeycomb is applied to the structure design of some astronomic payloads, and good effects are got.

Key words: Natural honeycomb, Astronautic payload, Structural design, Bionic design
