Abstract: We studied crushing performance and its analytical formula of the 3D printed Kagome honeycomb thin-walled stiffened structure, which was made of acrylonitrile butadiene styrene (ABS) plastics, and verified the crushing performance of isotropic Kagome honeycombs through experiments. According to the effective elastic modulus formula of orthogonally anisotropic Kagome honeycomb with plane structure, we gave the relationship among elastic modulus, relative density and shape anisotropy ratio of 3D printed Kagome honeycomb structure. Through analytical formulas and experimental results, we obtained the Kagome honeycomb structure with the best crushing performance. The method could be used to guide the design and processing of the stiffened structure of the rocket body.

Key words: Kagome honeycomb stiffened structure, additive manufacturing, mechanical property
