Combined Longitudinal and Transversal Compression of Beech Wood

Popis výsledku v původním jazyce

Longitudinal wood compression or pleating results in bendable wood. With longitudinal wood compression, the required bending force and the modulus of elasticity decrease dramatically and provide great bendability to the wood. The transversal compression of wood improves mainly its strength and hardness. Plasticized wood is put in a press and compressed in the transversal direction with a certain pressure and subsequently dried in this state. This results in a smaller thickness and higher density. If the press plates are shaped, the specimen will also have the same shape after the process, so the bending of wood is also possible with this process until the limited tension deformation along fibres allows the shaping of the specimen. Combination of these two methods could allow simple production of more curved wooden shapes with much higher strength compared to conventional bending methods. The aim of this research is to compare mechanical properties of shaped wood prepared by these three methods: longitudinally and transversally compressed (LTC), transversally compressed only (TC) and shaped specimens by the mould without compression (SWC).
