| 目的 研究在奇偶层交错方式下，交错角度对瓦楞纸板缓冲性能的影响。方法 将单瓦楞纸板按奇偶层交错的方式进行多层粘合以制备试样，交错角度分别为0°，30°，45°，60°和90°，采用共面静压、侧向静压和共面冲击的试验方法，对各试样共面和侧向的缓冲性能进行研究。结果 与奇偶层不交错的样品相比，在共面静压下，奇偶交错使瓦楞纸板的初始峰应力、平台应力、密实化单位体积变形能和密实化比吸能分别提高了4.15%~9.38%，6.49%~10.39%，5.00%~7.94%和7.43%~10.81%；在沿瓦楞方向侧向静压下，抗压强度和平台应力分别减少了1.18%~14.34%和0.89%~20.66%，密实化比吸能和密实化单位体积变形能与交错角度近似呈二次函数关系。在共面冲击载荷下，当交错角度一定时，总能量吸收与冲击能近似呈一次函数关系。结论 奇偶层交错一定角度能改善瓦楞纸板的共面缓冲性能，降低其沿瓦楞方向的侧向缓冲性能。 |

| The work aims to study influences of interleaving between odd and even layers on the cushioning performance of corrugated paper fiberboard. The single corrugated paper fiberboard was staggered in the interleaving manner between odd and even layers to multi-layer samples with the interleaving angles of 0º, 30º, 45º, 60º and 90º, respectively. The in-plane and lateral cushioning properties of the multi-layer corrugated paper fiberboard were studied under in-plane static compression, lateral static compression and in-plane impact loadings. In comparison with the multi-layer single corrugated paper fiberboard with the interleaving angles of 0º, under in-plane static compression, the interleaving between odd and even layers made the initial peak stress, plateau stress, densification stain energy per unit volume and densification specific absorption energy of multi-layer single corrugated paper fiberboard increase by 4.15%~9.38%, 6.49%~10.39%, 5.00%~7.94% and 7.43%~10.81%, respectively. Under the lateral compression along the corrugated direction, the compressive strength and plateau stress were reduced by 1.18%~14.34% and 0.89%~20.66%, respectively, while the densification specific energy absorption and plateau strain energy per unit volume were related with the interleaving angles by the law of approximate quadratic function relationship. Under in-plane impact loadings, the total energy absorption was approximately linearly with the impact energy for a given interleaving angle. Interleaving between odd and even layers at a certain angle can improve the in-plane cushioning performance of corrugated paper fiberboard and reduce its lateral compression performance along the corrugated direction. |
