This paper presents a study on a honeycomb paperboard filled with foam particles, investigating the effects of parameters such as cell size, honeycomb paperboard thickness, and foam particle size on interaction, energy absorption, and half wavelength. The experimental results demonstrate that foam particles increase the initial crushing strength and energy absorption of honeycomb paperboard, with the stress in the filled structure rising exponentially during crushing. Additionally, the research reveals a decrease in densification strain, an increase in the number of folds, and a decrease in half wavelength. Moreover, the smaller the foam particles, the greater the effect of filling.
In this paper a honeycomb paperboard filled with foam particles is presented. The effect of parameters such as the cell size, the honeycomb paperboard thickness and the foam particles size on the interaction, energy absorption capacity, and the half wavelength are investigated theoretically and experimentally. The experiment results show that foam particles of honeycomb paperboard increase their initial crushing strength and energy absorption and the stress in the honeycomb paperboard filled with foam particles rises exponentially during the crushing stage. Furthermore, decrease in the densification strain; increase in number of folds; and decrease in half wavelength are other results of this research. And the smaller the foam particles, the greater the effect of foam particles filling. In the theoretical section, the interaction between the foam particles and the honeycomb paperboard cell wall are studied by regarding as point contact. Expressions are derived to predict the stress and half wavelength of honeycomb paperboard filled with foam ```````````````````particles in the crushing stage. A comparison between theoretical predictions and experimental results shows that the theoretical models can effectively predict this stress. It is expected that these studies can help to improve the application of honeycomb paperboard and provide a reference for further research on foam particle filling.
