Abstract With the development of aerospace, civil architecture, chemical engineering and biomedicine, more and more metastructures have been applied. In this paper, a hybrid intersect beam honeycomb (HIBH) based on re-entrant hexagonal honeycomb (RHH) is proposed. This structure not only has negative Poisson's ratio (NPR) effect, but also has good energy absorption characteristics. By exploring the structural parameters, the parameters which can make the energy absorption characteristics of the structure reach the best state are found. Comparing HIBH with its parent structure and other structures, it is found that HIBH has better energy absorption capacity. In addition, the mechanical properties of the structure, including stress-strain characteristics, negative Poisson's ratio effect and densification strain, are investigated. Finally, the functional gradient is introduced to HIBH by changing its structural form, which further improves the energy absorption characteristics of HIBH. This indicates that the functional gradient can be introduced not only by changing thickness or size, but also by changing structure form. This method provides an idea for the introduction of functional gradient.
