“…The experimental results show that the load-carrying capacity and the energy absorption performance of paper honeycomb are insensitive to the loading speed in low strain rate range (10 −4 -10 −2 s −1 ). Wang and Bai [16] found that there exists a certain strain rate effect which leads to the difference of mechanical properties between dynamic and static condition. A mechanical model was given to estimate plateau stress and yield stress at different strain rates based on experimental data by employing the methods of Cowper-Symonds model and piecewise function.…”

Paper honeycomb sandwich panel is an environment-sensitive material. Its cushioning property is closely related to its structural factors, the temperature and humidity, random shocks, and vibration events in the logistics environment. In order to visually characterize the cushioning property of paper honeycomb sandwich panel in different logistics conditions, the energy absorption equation of per unit volume of paper honeycomb sandwich panel was constructed by piecewise function. The three-dimensional (3D) energy absorption diagram of paper honeycomb sandwich panel was constructed by connecting the inflexion of energy absorption curve. It takes into account the temperature, humidity, strain rate, and characteristics of the honeycomb structure. On the one hand, this diagram breaks through the limitation of the static compression curve of paper honeycomb sandwich panel, which depends on the test specimen and is applicable only to the standard condition. On the other hand, it breaks through the limitation of the conventional 2D energy absorption diagram which has less information. Elastic modulus was used to normalize the plateau stress and energy absorption per unit volume. This makes the 3D energy absorption diagram universal for different material sandwich panels. It provides a new theoretical basis for packaging optimized design.

“…In particular, paper [3] examines deformation of HF and its energy absorbing properties in the panels with different thicknesses under the uniform vertical static compression load. A comparison of HF work under static and dynamic loads [4] revealed that the rate of deformation of filler substantially affects its mechanical properties. When studying the performance of honeycomb panels under dynamic loads, the energy absorbing properties of HF were also investigated depending on the impact velocity and defects of the walls of the cells [5].…”

“…7 After printing of the honeycomb structure, multiple density ratios were compared from two different filament types. 16 It concluded that, from testing cycles, paper honeycombs reached the maximum yield stress then undergo plastic deformation, which leads to the plateau stage where most of the absorption energy was gathered from. This deformation is much different from a structure placed under compression in the transverse direction, where the cell walls only bend but do not Additional Supporting Information may be found in the online version of this article.…”

Polycaprolactone is well known as a healing agent material in crack self-healing applications but not as a structural material. In this study, the focus is on the durability and energy absorption of honeycomb structure made from polycaprolactone through three-dimensional (3D) printing. The mechanical behavior of honeycomb structures was investigated through in-plane quasi-static compression tests at temperatures of 5 8C, room temperature (22 8C), and 40 8C. Energy absorption efficiency and energy absorption capability at different temperatures and in different loading directions was investigated according to the selected stepping upward stress. The "shape recovery" ratio after compression deformation was calculated. The results reveal that the polymeric honeycomb structure has exceptional repeatability under compressive loads. Specimens with relative density 0.20 showed high energy absorption capability, up to 0.988 J cm 23 . After the removal of compression loads, specimens recovered up to 80% after the first deformation and up to 70% after the fifth deformation.
