预压缩多层钙塑瓦楞纸板准静态压缩与动态缓冲性能研究

对不同预压程度下多层钙塑瓦楞纸板缓冲衬垫的力学性能以及缓冲特性进行了研究。通过静态压缩试验对比了缓冲衬垫在不同预压缩程度下的力学性能以及缓冲特性。将材料的应力-应变曲线转化为缓冲系数-最大应力曲线，从而获得最小缓冲系数，研究发现压缩率为5%到25%的缓冲材料可以有效地扩大缓冲保护范围。通过连续冲击试验得到了多层钙塑瓦楞纸板缓冲衬垫在连续冲击载荷条件下的冲击响应，利用加速度-时间曲线和冲击放大系数曲线分析了缓冲衬垫的缓冲特性。研究结果将对多层钙塑瓦楞纸板在缓冲包装设计中的应用起到一定的参考价值。

Research on mechanical and cushioning properties of calcium plastic corrugated paper board with different pre-compression ratio

The mechanical and cushioning properties of the multilayer calcium plastic corrugated paper board(CPCPB) with different pre-compression ratio is investigated here. Mechanical and cushioning properties with different pre-compression ratio are compared though static compression tests. And the minimum cushion coefficient can be got from the “cushion coefficient-static loading” curve, which is changed from the “stress-strain” curve. It is shown that the compression ratio from 5% to 25% can expanded the cushion protect range. Then, the shock response of the CPCPB under repetitive shocks is got though repetitive shocks test. The cushioning properties of the multilayer CPCPB can also be studied by “acceleration-time” curve and shock amplification factor curve. The results can be good reference for the further research woks of cushion packaging design.
