Lepljen les za konstrukcijske namene : diplomsko delo : visokošolski strokovni študij = Glued wood for construction purposes : graduation thesis : higher professional studiesŠčernjavič, DaniloRaziskovali smo mehanske lastnosti različnih lesnih vrst in iz njih izdelanih kompozitov, ter možnost njihove uporabe v konstrukcijske namene. Uporabili smo 2 vrsti lepila in lesne vrste: bukev, ... smreko, macesen, lipo, brezo in jelšo. Lesove smo med sabo kombinirali v različne sestave lesnih kompozitov in jih nato lepili po vročem ali hladnem postopku. Iz teh lepljencev smo izdelali preskušance za ugotavljanje mehanskih lastnosti, vlažnosti in gostote. Po lepljenju smo izmerili in izračunali tudi izgubo debeline. Preizkus mehanskih lastnosti smo izvajali s pomočjo univerzalnega testirnega stroja Zwick Z100 po standardu SIST EN 310. Gostoto smo merili po standardu SIST EN 323, vlažnost pa po standardu SIST EN 322. Ugotovili smo, da so mehanske lastnosti lesnih kompozitov boljše kot mehanske lastnosti samega masivnega lesa. Prav tako pa imajo lesni kompoziti, zlepljeni po vročem postopku, boljše mehanske lastnosti od lesnih kompozitov, zlepljenih po hladnem postopku. Pri merjenju vlažnosti smo ugotovili, da ni bilo bistvenih razlik med masivnim lesom in lesnimi kompoziti Ugotovili smo tudi, da z lepljenjem lesa povečamo gostoto preskušancev. Lesni kompoziti, zlepljeni po vročem postopku, so imeli največjo, masiven les pa najmanjšo, gostoto.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [D.
