EPE / EPS 与蜂窝纸板组合静态缓冲性能的研究

以EPE与蜂窝纸板组合结构和EPS与蜂窝纸板组合结构为研究对象,通过静态压缩试验得到了3种材料和2种组合结构的应力-应变曲线和缓冲系数曲线。对比分析表明,组合结构力学性能得到了改善;较小应力状态下,组合结构分别呈现出EPE和EPS的缓冲性能,且EPE与蜂窝纸板组合结构的缓冲性能优于EPS与蜂窝纸板组合;压缩中间阶段,2种组合结构缓冲曲线基本重合,且接近于蜂窝纸板缓冲曲线;压缩后期,较大应力条件下,组合结构仍有一定的缓冲性能。组合后的材料结合了2种材料的优点,在较小应力和较大应力条件下均具有较好的缓冲性能。

Study on Static Cushion Performance of EPE/ EPS and Honeycomb Paperboard Combination

EPE and honeycomb paperboard combination, and EPS and honeycomb paperboard combination were taken as objects. Static compression test were carried out and the stress-strain curves and cushion coefficient curves of the three materials and two combinations were obtained. The result showed that the mechanical performance of combination structure is better; at the smaller stress, the combination structure presented the cushion performance of EPE and EPS respectively; and EPE and honeycomb paperboard combination is superior to EPS and honeycomb paperboard combination; in the intermediate stage of compression, the cushion performance curves of the two combination structures are basically identical, which are similar with the honeycomb paperboard; at the later larger stress stage, the combination structures still have some cushion ability. The combination structures combine the advantages of the two materials, and have better cushion performance under smaller or larger stress.
