英文摘要： Fiber-based cushioning material is a type of environment friendly packaging material meeting the demand of sustainable development, thus is widely used in packaging field. Honeycomb paperboard, corrugated paperboard and fiber-based foaming material are fiber-based cushioning materials used most extensively nowadays.They can be applied in distribution chains as energy absorbers or cushions to protect products from accidental impacts,therefore,the prediction of the energy absorption properties of fiber-based cushioning material is essential to energineering application. Energy absorption properties of honeycomb paperboard, corrugated paperboard and fiber-based foaming material were investigated in this project,the effect of relative humidy in logistical environment on the energy absorption properties of these materials were explored,and energy absorption mechanism were analyzed relatively. Based on these, energy absorption prediction models were constructed and normalized energy absorption diagrams were plotted according to these models. Combining the energy absorption prediction models and energy absorption diagrams, packaging designers can characterise the energy absorption properties of fiber-based cushioning materials in actual logistic environment, therefore to optimise structure design of these material
