纸夹芯和泡沫复合层状结构的静态缓冲吸能特性研究
|
摘要
针对由发泡聚乙烯(EPE)、瓦楞纸板、蜂窝纸板组成的复合层状结构的包装防护作用,通过实验对比分析了这类结构的横向静态压缩变形特征和缓冲吸能特性。结果表明,这类结构在压缩初始阶段和最后阶段主要表现为EPE的力学性能,而在中间阶段为瓦楞纸板、蜂窝纸板的力学性能。复合层状结构的弹性模量、总吸能、行程利用率均高于EPE,而单位体积变形能则由于试样厚度增加幅值不同,并未表现出与总吸能一致的变化规律。比吸能随着压缩应变增大而增加,几乎不受压缩速度的影响,其中EPE与蜂窝纸板复合层状结构的比吸能均大于EPE与瓦楞纸板复合结构。在应力水平较小时,EPE与瓦楞纸板复合层状结构的能量吸收效率大,然而在应力水平较大时,EPE与蜂窝纸板复合的能量吸收效率大。
For the packaging protection of the composite layered structures including corrugated paperboard, honeycomb paperboard, and expandable polyethylene(EPE), the transverse static compression deformation and the cushioning energy absorption of these structures were analyzed experimentally. The results show that: these structures embody the mechanical properties of EPE in the initial and final compression stages, and reflect the mechanical properties of corrugated paperboard or honeycomb paperboard in the middle stage. The elastic modulus, total energy absorption and stroke efficiency of the composite layered structures are higher than those of EPE, while the unit volume deformation energy does not show the identical change rule as the total energy absorption because of the different amplitude of specimen thickness. The specific energy absorption rises with the increase of compression strain, and not affected by the compression speed. The specific energy absorption of composite layered structures with EPE and honeycomb paperboard is greater than those of EPE and corrugated paperboard. The energy absorption efficiency of the EPE and of the corrugated paperboard composite layered structures is larger at the low stress level, yet that of the EPE and of the honeycomb paperboard composite layeredstructures is greater at the high stress level.
