“…Several studies focused on out‐plane bearing and buffering of honeycomb paperboard with different cell thicknesses, and out‐plane critical load models and platform stress models were successively established. Simultaneously, based on an energy absorption diagram, the out‐plane cushioning performance and out‐plane compacting compression evaluation of honeycomb paperboard are also examined.…”

The in‐plane bearing capacity of the face layer and core layer of a honeycomb paperboard is limited and unstable. However, a combination of the face layer and core layer of the honeycomb paperboard protects cardboard from small‐load buckling instability and provides sufficient stiffness and bearing strength. In the study, the platform theory models of the machine direction and cross direction are established based on plastic deformation, plastic energy dissipation, and the energy conservation theory. Additionally, the marginal pressure strength in the machine direction and cross direction are deduced by combining the practical application of the honeycomb paperboard. A comparison of theoretical and experimental data indicates that the two are in good agreement. Therefore, the theoretical results of the study provide a theoretical basis for the scientific and reasonable selection of important parameters of honeycomb paperboards with different strength requirements.

“…One such light weight technology is the application of sandwich materials such as honeycomb sandwich structures. These are widely used in light-weight engineering and hence are not only increasingly used in the automotive sector [1] but have been prominent for long in shipbuilding [2], aerospace [3], and transport packaging [4]. Although, honeycomb structures provide good structural properties, their damping behaviour is mostly poor compared to structures with a higher volumetric density, leading to higher structural and acoustic response.…”

The damping plays a vital role in structural dynamic and acoustic performance of aluminium honeycomb sandwich structures. The viscoelastic damping treatment of skins is most common. An alternative, the use of sustainable cork inserts to improve the damping of cores and the whole assembly is investigated in this study. Structures with different filling degrees are analysed as well as the optimum location for inserts is determined. The structural dynamic as well as the vibro-acoustic performance is estimated numerically. Average squared displacement amplitude reduction efficiency 2 ̅̅̅̅ ̅̅̅̅̅ is defined as the target parameter for structural dynamic performance, whereas average transmission loss effectiveness ̅̅̅̅̅ for vibro-acoustic performance. The structural dynamic models are validated by experimental vibration analysis, whereas the vibro-acoustic models are validated against published data. Different ways of bonding the inserts to the host structure are analysed in order to maximise damping. The highest improvement is obtained with a filling degree of 64% honeycomb voids and 9.76% increase in mass, for which an average squared displacement amplitude reduction of 35.25% and an average increase in transmission loss of 1.5dB is achieved. The transmission loss increase in relation to the added mass is much higher than that achieved by doubling of mass in the mass law region. The introduction of cork inserts spreads the energy in local modes to a larger space, effectively decreasing the resonance amplitudes. Interestingly, damping does not increase with the number of inserts in a monotonic way and the improvement depends on the spatial distribution of inserts.2

Packaging products in logistics typically will receive multiple low‐intensity repeated impacts, fewer moderate to high‐intensity impacts and vibration. As a result of low‐intensity repeated impacts, local buckling and fold will be formed in honeycomb paperboard, and its cushioning performance will be weakened. This paper investigates the influence of low‐intensity repeated impacts on the cushioning performance of honeycomb paperboard. The low‐intensity repeated impacts with dropping height 5 cm were conducted at first. Then, the moderate‐intensity impact with dropping height 80 cm and vibration experiment were, respectively, conducted. The results show: (a) honeycomb paperboard absorbs the energy produced by low‐intensity repeated impacts through layer upon layer folding of honeycomb structure. The highest buckling peak turns up in low‐intensity impact, followed by a series of buckling in intact honeycomb paperboard. However, the buckling is not obvious in repeated impacts; (b) the load carrying capacity of honeycomb paperboard after low‐intensity repeated impacts declines significantly. Three deformation stages are observed in the load–displacement curve. Most of impact energy is absorbed in the plateau stage. The absorbed energy of damaged honeycomb paperboard under moderate‐intensity impact decreases with the increasing of low‐intensity impact repetitions; and (c) the low‐intensity repeated impacts have an obvious influence on the resonance frequency of packaging product and stiffness of honeycomb paperboard. To confirm vibration properties of product using honeycomb paperboard cushioning, it should be considered in a designing process that honeycomb paperboard changes soften more in logistics.
