| 目的 依据包装缓冲设计及动力学理论分析新型环保纸蜂窝夹芯板的最佳厚度。方法 通过平压实验、 弯曲实验、 抗冲击实验和单点吊挂实验分析蜂窝纸板的各项力学性能。结果 平压实验时， 压溃过程呈先后顺序， 其压力-位移曲线呈双峰形态。在复合材料中间部位施加压力时， 压力可达板自重的0.75倍以上， 70~110 mm厚的板均能承受30 kg的大软体冲击（冲击高度为500 mm）， 满足墙体抗冲击性能标准； 厚度小于90 mm的墙板， 其损坏情况为孔洞周围石膏板被压溃， 表现为轻微损伤； 厚度大于90 mm的墙板， 其力学性能良好。结论 墙板的最佳厚度为90 mm。 |
| 英文摘要: |
| On the basis of the theories and techniques pertinent to dynamics of package cushioning design, the optimal thickness of the new environment friendly paper honeycomb sandwich panel was analyzed in this paper. Through flat compression test, bending test, impact resistance test and single-point hanging test, the mechanical properties of the honeycomb paperboard were analyzed. In the flat crush test, the collapsing process showed the phenomenon of sequential occurrence, and the pressure-displacement curves were featured by the double-peak shape. When pressure was applied in the middle of the composite material, it could reach a value up to 75% of the gravity of the panel itself. The honeycomb panel with a thickness of 70 mm to 110 mm could tolerate the flexible shock of 30 kg (for shock height of 500 mm), thus meeting the standards of wall impact performance. The damage to the panels with a thickness of less than 90 mm was attributable to the slight collapse of the plaster panels around the hole. The mechanical properties of the wall panels with a thickness exceeding 90 mm were good. 90 mm was the optimal thickness of the paper honeycomb sandwiched wall panels. |
