Abstract
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.
Claims10
A process producing a composite wood specimen having greatly increased elasticity, which process comprises:
- supplying at least two specimens of diffuse-porous wood which have been made elastic by isostatically pressing said specimens with a pressure of at least 500 bars;
- and
- gluing said specimens together in such a manner that the fibres are oriented in parallel in a resulting composite wood specimen.
