Experimental Investigation into the Static Cushioning Properties of Rhombic Honeycomb Paperboard
The cushioning characteristics of honeycomb paperboards with rhombic core were investigated and compared with the conventional hexagonal honeycomb paperboards. The compressing tests under low-velocity impact loads were performed to analyze stresses and deformation behaviors of specimens based on stress-strain curves and cushioning coefficient-strain curves. The results show that, compared of the hexagonal core, the rhombic core structure is able to decrease the rigidity and improve the initial cushioning properties of honeycomb paperboard. It is more benefit for packaging fragile items.
