The mechanical behaviour of veneer subjected to bending and tensile loads

摘要

Bending and tensile tests were carried out on veneer of beech (Fagus sylvatica L.) and European oak (Quercus robur L./Quercus petraea Liebl.) with a thickness between 0.35 mm and 0.5 mm. The tests were done on veneer in two test series, one parallel to the fibre and the other one perpendicular to the fibre. Mechanical properties and bending radiuses were measured and evaluated. It could be concluded that the bending properties of the veneers not only depend on the bending stiffness but also the mechanical strength and structure of the material. During the tests it could be shown that the 3-point bending test procedure is not a suitable method for determining the bending modulus of rupture.
