To improve the mechanical properties of out-of-plane of honeycomb structure,the ribbed plate structure was introduced based on the traditional hexagonal honeycomb,which was coupled into a new type of filling-type with ribbed plate honeycomb structure.The im-pact response characteristics and energy absorption capacity of the out-of-plane of filling-type with ribbed plate honeycomb structure with different impact velocities and impact angles were studied using the explicit dynamic finite element method.The results show that the de-formation modes of the filling-type with ribbed plate honeycomb are affected by the impact velocity and impact angle,and there is a cou-pling enhancement effect between the filled ribbed plates and the external cell-wall,which can enhance the mechanical properties of the honeycomb and increase energy absorption by 15.08％.The plateau stresses of the impact end and fixed end decrease with the increase of impact angle.The dynamic bearing capacity decrease with the increase of impact angle.Relative density affects the coupling effect be-tween the filled ribbed plates and the external cell-wall and the energy absorption capacity of filling-type with ribbed plate honeycomb structure.
