The invention relates to a process for greatly increasing the elasticity and bendability of diffuse-porous wood and comprises the following steps: a) supplying a specimen of diffuse-porous wood; and b) isostatically pressing the specimen in a) with a pressure of at least 500 bar. The rigidity is increased once again by immersing the wood specimen in a liquid for up to 2 hours, after which the specimen is dried. This can be utilized when producing shaped products made of diffuse-porous wood.
L'invention concerne un procédé permettant d'augmenter considérablement l'élasticité et l'aptitude au pliage du bois à pores diffus. Ce procédé consiste a) à fournir un échantillon de bois à pores diffus; et b) à presser isostatiquement l'échantillon obtenu en a) à une pression d'au moins 500 bar. Pour augmenter la rigidité, l'échantillon de bois est immergé dans un liquide pendant 2 heures puis séché. Ce procédé peut être utilisé lors de la production de produits usinés réalisés en bois à pores diffus.
