Abstract

V zadnjih letih se veliko raziskav opravlja na področju utekočinjanja lesa, ki ga lahko uporabljamo tudi kot surovino za izdelavo poliuretanskih pen. Glede na to, da so trendi v pohištveni industriji zopet vse bolj osredotočeni na izdelavo pohištva iz lahkih ploščnih kompozitov, smo ustvarili nov lahki ploščni kompozit s srednjim slojem iz poliuretanske pene iz utekočinjenega lesa, ki bi ga lahko uporabili v pohištvene namene. Delo je obsegalo izdelavo kompozitov in testiranje preizkušancev. Preizkušali smo odpornost proti tlaku, upogibno trdnost ter dimenzijsko obstojnost. Dosežene vrednosti lahko najbolj primerjamo s poliuretansko peno in s papirnatimi satovji, medtem ko so vrednosti aluminijevih, polipropilenskih in polietilenskih satovij neprimerljivo višje. Ugotovili smo, da moramo za doseganje boljših mehanskih lastnosti plošče kondicionirati. Dodatno bi lahko lastnosti izboljšali z obdelavo robov.

Secondary title:	Development of light wood composites with core from liquified wood
Secondary abstract:	In recent years there has been much research on wood liquefaction and polyurethane foam produced from liquefied wood. Given that the trends in the furniture production industry are again focused on lightweight materials, we have developed a new light wood composite, where the core layer was made from liquefied wood. Such panels could be used in the furniture production. We have successfully constructed such panels and then tested the compressive and bending strength and the dimensional stability. Values obtained can best be compared with those from polyurethane foam and paper honeycomb, while aluminium, polypropylene and polyethylene honeycomb values were incomparably higher. Our results show that after the production we have to condition the panels. Additional features could be improved by closing the edges with edge band from solid wood or even ABS.
