AB - The aim of the present study was to find and describe the relationship between damping properties and both the number of layers and the fiber orientation in wood-veneer-composite specimens. The testing apparatus was a simple torsional pendulum in which the frequencies of the resulting free vibrations were maintained between 13 and 23 Hz. Cross-sectional (30 × 30 mm) specimens with a total length of 250 mm were used. The specimens were cut from manufactured wood-veneer-composite panels (both 0°/90° and 0°/0° oriented) with up to 13 layers. Existing problems such as nonlinearities, which are often responsible for weighting results, were taken into account by using several mathematical approaches. The results led to a consistent picture of the damping properties across the measured range. We found that the damping ratio increased for the 0°/90° orientation with increasing numbers of layers in a cross-sectional specimen of constant outer dimensions. This effect could not be reproduced for specimens oriented 0°/0°.
