The influence of densification time on the tensile strength and modulus of elasticity of birch veneers
The influence of densification time on the tensile strength and modulus of elasticity of birch veneers. The aim of the following study was to examine and compare tensile strength, modulus of elasticity, and thickness of birch (Betula pendula Roth) veneers modified by thermomechanical densification. Birch veneers were densified at the temperature of 100 °C at different times (ranges from 10 to 60 minutes). Tensile strength was tested longitudinally to the grain. As a result of this study change in tensile strength was observed for 60 minutes of densification. The rise in modulus of elasticity was also observed for 10, 20, 30, 50, and 60 minutes. The thickness of wooden veneers was changed significantly for each densification time
