Repák, Miroslav, 1993- Physico-mechanical properties of thermally modified wood affected by its pre-treatment with polyethylene glycol / Miroslav Repák, Ladislav Reinprecht. -- Graf., tab. -- Lit. - The European beech (Fagus sylvaticaL.) wood–natural,as well aspre-treated with 20 wt.% water solution of polyethylene glycol (PEG 6000) – was thermally modified at the temperatures of 170, 190 or 210 °C for 1, 2, 3 or 4 hours. The selected properties of thermally modified beech wood, i.e. soaking, volume swelling, impact bending strength and Brinell hardness changed more intensively at using more severe thermal regimes from 170 °C / 1 h to 210 °C / 4 h. The presence of polar, white-waxy consistency of polyethylene glycol macromolecules in the thermally modified beech wood specimens had different effects on their properties. PEG 6000 participated insupressing the volume swelling and soaking in water of the thermally modified beech wood specimens, and also inhibited a decrease of their impact bending strength. On the contrary, polar PEG 6000 macromolecules together with thermal loads participated in decreasing the Brinell hardness.
