逐层交错对瓦楞纸板静态缓冲性能的影响

目的 研究在逐层交错的方式下，交错角度对瓦楞纸板静态缓冲性能的影响。方法 将单瓦楞纸板以逐层交错的方式粘合，制得0°，30°，45°，60°，90°等5种角度的试样，通过平压试验和侧压试验，研究交错角度对瓦楞纸板承载性能和吸能性能的影响。结果 交错角度对试样的密实化应变影响较小；在侧压试验中，交错角度在0°~45°之间时，试样的侧压强度和比吸能随着角度的增大而减小；交错角度在45°~90°之间时，随着角度的增大，试样的侧压强度和比吸能先增大后减小；在平压试验中，交错角度对试样的平均抗压强度和比吸能影响较小。结论 交错角度对瓦楞纸板侧压缓冲性能影响较大，对平压缓冲性能影响较小。

Influences of Interlacement Mode Layer by Layer on Static Cushioning Properties of Corrugated Paperboard

This paper aims to study influences of interlacement mode layer by layer on static cushioning properties of corrugated paperboard. Single corrugated paperboards were glued with the interlacement mode to obtain specimens with five different interlacement angles of 0°, 30°, 45°, 60° and 90°. By edgewise compressive test and flatwise compressive test, influences of interlacement angles on the bearing capacity and energy absorbing capacity of corrugated paperboard were studied. The results show that interlacement angles had little effect on the densification strain of specimens. In edgewise compressive test, when the interlacement angles were between 0°~45°, the edgewise compressive strength and specific energy absorption decreased with the increase of interlacement angles. However, the edgewise compressive strength and specific energy absorption of specimens first increased and then decreased with the increase of interlacement angles when the angels were between 45°~90°. In the flatwise compressive test, interlacement angles had little influence on the mean crushing strength and specific energy absorption of specimens. Therefore, it is concluded that interlacement angles have great influence on the edgewise compressive cushioning properties, and have little influence on the flatwise compressive cushioning properties of corrugated paperboard.
