Research On Energy Absorption Model Of Paper Honeycomb Structure Based On Temperature And Humidity Effect

In recent years paper honeycomb which appear in Europe, America, Japan andChina is an environment-friendly, low-cost and new green packaging cushioningmaterial. It has four advantages which are light, strong, firm and stable. It embodiesa new model and the concept of packaging. As an environment-friendly material, itnot only can degrade, do not pollute the environment and recycle, but also canreplace the wood, which greatly reduce the usage of wood to protect the dwindlingforest resources.The influence of the temperature and relative humidity on the moisture contentof corrugated paper and paper honeycomb was studied by experiments in the study.Based on the experimental results, the optimum mathematical models of themoisture content of the corrugated paper and paper honeycomb were fitted inaccordance with three classic models by matlab. The influence of the moisturecontent on the mechanical properties of corrugated paper was studied, and therelationships between the elastic modulus, the yielding stress and the moisturecontent of corrugated paper were discussed. Combined with the mathematicalmodel of the moisture content of the corrugated paper, the prediction equations ofthe relative elastic modulus and the relative yielding stress of corrugated paper werefitted after analyzing experimental results by matlab and then were verified. Thestatic compressive mechanical behavior and cushioning mechanism of paperhoneycomb were analyzed, and then the relationships between the critical stress,plateau stress and the moisture content of paper honeycomb were studied. Theprediction equations of the critical stress and plateau stress of paper honeycombwere deduced and then were verified. Combined the research mentioned above, theenergy absorption diagram of paper honeycomb corresponding to the moisturecontent and thickness-to-length was plotted. The diagram can be made use of tooptimize the packaging design of paper honeycomb.The study is meaningful to study the cushioning property of paper honeycomb.And it has practical significance on optimizing the packaging design of paper honeycomb by using energy absorption diagram.
