Calculation of honeycomb paperboard flat crush resistance
The article presents calculation methods for flat-crush resistance (FCT) of honeycomb paperboard. The calculations were made on the bases of mechanical properties of the material that is, paper used for core production and shape of its cells. The methods presented in the article allow to calculate the FCT for the cores with the cells of the theoretical hexagon shape as well as of the real shape. The correctness of the methods proposed was verified by the comparison of calculation results with the results of FCT measurements for boards of different core height.
