Modelling of Thin Paper Honeycomb Panels for Furniture

Thin cellular wood panels have been gaining increasing interest among furniture manufacturers but only few articles can be found dealing with modelling of mechanical properties of cellular wood panels with a paper honeycomb core inside. The aim of the presented study was to ascertain mechanical behaviour of thin cellular wood panels (18 mm) manufactured from a paper honeycomb of hexagonal cells. Investigations were performed employing analytical models, carrying out experimental measurements and comparing the obtained results with the results of numerical calculations. It was demonstrated that cores of the examined cellular wood panels exhibited strong orthotropic properties. Results of numerical calculations of sandwich beam deflections corroborated their satisfactory conformity with the results of laboratory measurements proving the correctness of the determined elastic constants.
