Modelling stiffness of furniture manufactured from honeycomb panels depending on changing climate conditions

摘要

Furniture users as a rule consider low prices, lower product weight and easy transport of furniture items to the intended location as obvious advantages. However, practically no studies in available literature are found to assess the effect of variable climate conditions on the stiffness of shelves and furniture made from honeycomb panels. The aim of this study was to determine the effect of these changes on the value of Young's modulus and on the stiffness of whole furniture units subjected to torsional loads. Tests were performed on furniture units, which elements were manufactured in five structural design variants. It was shown that the applied materials retain high quality of the furniture units only at the temperature T = 26 degrees C and humidity H = 40%. An increase in the values of these climate parameters to T = 28 degrees C and H = 85% results in a drastic deterioration of furniture quality.
