Impact behavior and energy absorption of paper honeycomb sandwich panels

Dynamic cushioning tests were conducted by free drop and shock absorption principle. The effect of paper honeycomb structure factors on the impact behavior was analyzed. Results of many experiments show that the dynamic impact curve of paper honeycomb sandwich panel is concave and upward; the thickness and length of honeycomb cell-wall have a great effect on its cushioning properties; increasing the relative density of paper honeycomb can improve the energy absorption ability of the sandwich panels; the thickness of paper honeycomb core has an up and down fluctuant effect on the cushioning properties; with the increase of the thickness of paper honeycomb core, the effect dies down; flexible corrugated paperboard as liners can improve the compression resistance and cushioning properties of paper honeycombs. The research results can be used to optimize the structure design of paper honeycomb sandwich panel and material selection for packaging design.

The effect of compression of enclosed air on the cushioning properties of corrugated fibreboard

This work showed that the shock‐absorbing properties of corrugated fibreboard are dependent on the size of the cushion even when the static loading of the impacting product on the cushion is kept a constant. At least part of this phenomenon was found to be due to the effect of the air enclosed within the flutes of fibreboard cushions. During the dynamic compression of fibreboard pads there is a build‐up of air pressure within the cushion, which improves its cushioning performance. The greater ease with which air can escape smaller fibreboard cushions, leads to differences in their shock‐absorbing behaviour compared with larger cushions. Suggestions are made on how the design of fibreboard pads can be modified to increase the build‐up of air pressure within the flutes and improve the efficiency of the cushion. For comparison, expanded polyethylene foam was also examined and its shock absorbing properties were found to be largely independent of cushion size for constant static‐loading impacts.

Flexural stiffness of selected corrugated structures

Top‐to‐bottom compression strength of a corrugated fibreboard box is partly dependent on the load‐carrying ability of central panel areas of the box. The ability of these central panel areas to resist a bending force from loading may increase the stacking strength of the box. The difference in the compression strengths of boxes that have identical dimensions and were fabricated with identical components but different flute types, is primarily caused by flexural stiffness of the box panels. Top‐to‐bottom compression strength of boxes can be accurately predicted by flexural stiffness measurements and edge crush test (ECT) of the combined boards. This study was carried out to analyse the flexural stiffness, to measure bending force and bending deflection by a four‐point bending test for various corrugated fibreboards, and to provide the major constructional factors which play a role in improving the compression strength of the box.
