摘要
目的为了新型纸蜂窝夹芯复合板材在运输包装中的推广应用,对新型泡状纸蜂窝夹芯复合板和纸蜂窝夹芯复合平板的缓冲性能和吸能特性进行研究。方法主要通过静态压缩实验,研究不同芯高的纸蜂窝结构类板材的应力-应变曲线、总能量吸收图、单位体积能量吸收图和缓冲系数-应变曲线,分析结构和芯高对板材静态压缩性能的影响。结果数据表明同种芯高的板材,纸蜂窝夹芯复合平板的应力峰值稍高;纸蜂窝夹芯复合平板的能量吸收、单位体积能量吸收最好;泡状纸蜂窝夹芯板由于泡结构的作用,缓冲性能大大增强。结论纸蜂窝夹芯复合平板的平压强度最好,而泡状纸蜂窝夹芯复合板的缓冲性能优于同等结构的蜂窝纸板,2种板材都有很好的应用前景。
The work aims to research the cushioning performance and energy absorption characteristics of new bubble paper honeycomb sandwich composite board and paper honeycomb sandwich composite board to widely use the new honeycomb sandwich composite board in transportation packaging.The stress-strain curves,total energy absorption charts,unit volume energy absorption charts and cushioning coefficient-strain curves of honeycomb structural boards with different core heights were studied by static compression experiments to analyze the effects of structure and core heights on the static compression properties of honeycomb structural boards.The data show that the peak stress of paper honeycomb sandwich composite boards was slightly higher than other boards with the same core height.The total energy absorption and the energy absorption per unit volume of paper honeycomb sandwich composite boards were the best.Due to the effect of bubbles structure,the cushioning property of bubble paper honeycomb sandwich composite board was greatly enhanced.Therefore,it is concluded that the paper honeycomb sandwich composite boards have the best flat compression strength and the cushioning performance of the bubble paper honeycomb sandwich composite board is better than that of the honeycomb paperboard with the same structure.Both of them have good application prospects.
