Shape stability of chosen thin wood based panels after heating. Lignocellulose board materials are
commonly used for furniture construction. Typically, these are particle boards, fibreboard or plywood with
thicknesses from 10 to 20 mm, however, some furniture elements are made of thin boards with a thickness of 3-4
mm (back walls, bottoms of drawers and others). Modern furniture uses built-in components that are a source of
heat, such as lamps, power supplies, ovens. Local high temperature may negatively affect the shape stability of
thin lignocellulose plates. The aim of the research described in this article was to determine the impact of shortterm
exposure to high temperature on the dimensional stability of selected thin plate furniture materials. Four
different HDF boards with nominal thicknesses of 3 mm and four different plywood boards with nominal
thicknesses of 2 to 4 mm were tested. The test samples were subjected to a short-term exposure to temperatures
of up to 250°C. As a result of the tests, it was found that HDF boards are characterized by a much higher shape
stability at elevated temperature than boards made of plywood.
