20.500.12556/RUL-117567 Izdelava lahkega ploščnega kompozita s 3D oblikovano sredico diplomski projekt Fabrication of lightweight wood composite with 3D formed core V zadnjem času se na tržišču vse bolj pojavljajo lahki ploščni kompoziti, s sredico iz aluminija ali sintetičnih polimernih materialov. Ti materiali so za izdelavo večinoma energetsko potratni zato iščemo rešitve, v katerih bi satovja vsebovala komponente masivnega lesa ter drugih lesnih materialov. Nova satovja bi predstavljala alternativne možnosti obstoječim papirnatim sredicam. Satovja smo skonstruirali v programu SolidWorks, izdelali kompozite in ugotavljali njihove lastnosti. Preizkušali smo tlačno in upogibno trdnost plošč. Rezultati testiranj so pokazali boljše mehanske trdnosti naših plošč v primerjavi s ploščami iz papirnatih satovij. Ugotovili smo, da bi lahki ploščni kompoziti s sredico iz masivnega lesa in MDF plošče ustrezali zahtevam uporabe v pohištveni industriji. In recent years there has been increase of interest on market of lightweight wood composites with cores made of metal and synthetic materials. To make these materials is energy inefficient; therefore, we decided to incorporate hard wood and MDF in fabrication of cores, as an alternative to paper honeycomb and other non-wood materials. Different cores were designed using computer engineering program SolidWorks; then boards were fabricated and physically tested for bending and compressing strength. The results of the tests were compared to industrially made lightweight wood panels and have shown that our core could withstand greater loads than paper honeycomb panels. Based on the results the sandwich boards could be used in furniture industry. lahki ploščni kompoziti satovje furnirno satovje MDF satovje light wood composites honeycomb veneer honeycomb core MDF honeycomb core true false false [B.
