摘　　要：面内平台应力是评估蜂窝纸板面内承载性能的重要指标,且蜂窝纸板性能极易受环境湿度的影响。该文试验分析蜂窝纸板厚度、芯层和面层对其面内平台应力的影响;基于不同相对湿度条件下蜂窝原纸的纵向屈服强度,建立了相对湿度影响的蜂窝纸板面内平台应力模型,并与试验实测数据进行比较验证。结果表明:纸板厚度和面纸性能对蜂窝纸板面内平台应力有较大影响,芯层性能对其影响较小;所建立模型能较准确地反映环境相对湿度对纸蜂窝结构材料面内平台应力的影响。借助该模型,无需大量的试验,即可估算其考虑相对湿度的面内平台应力,为蜂窝纸板的配纸和合理选用提供理论依据。In-plane plateau stress is an important index to evaluate the in-plane yield strength of honeycomb paperboards, which is sensitive to relative humidity. The effects of thicknesses, core layers, and liners on the in-plane plateau stress of honeycomb paperboard were investigated by experiments. The in-plane bearing capacity is undertaken by both liners and core layers of honeycomb paperboards. The in-plane plateau stress model of honeycomb paperboard considering the effect of relative humidity was proposed based on the longitudinal yield strength of honeycomb paper under different humidity conditions, which was compared with the experimental data. The results show that the thickness and liner materials of honeycomb paperboard have great influence on the in-plane plateau stress, on which the core layers has little influence; The model can effectively reflects the influence of relative humidity conditions on the plateau stress of honeycomb Danerboards
