Abstract Based to the typical re-entrant honeycomb structure with negative Poisson's ratio, a new type re-entrant honeycomb structure with negative Poisson's ratio and angle gradient was designed. The finite element model of re-entrant honeycomb structure with two kinds of angle gradient changes, namely bidirectional increasing and bidirectional decreasing, was established. A quasi-static experiment was carried out to compare the energy absorption effect of typical honeycomb structures with negative Poisson's ratio and re-entrant honeycombs structure with bidirectional angle gradient. The deformation mode, platform stress and energy absorption characteristics of two types of re-entrant honeycomb structures with angle gradient under in-plane inclined impact loading were studied by using finite element software ABAQUS/Explicit. The results show that when the impact angle is 2° and the angle gradient is 3°, the new type gradient structure has higher platform stress and better energy absorption mode.

Key words： re-entrant honeycomb with angle-gradient in-plane inclined impact negative Poisson’s ratio effect platform stress energy absorption
