Kakovost epoksidnega lepilnega spoja med lesom in jeklom : diplomsko delo = The quality of the epoxy adhesive bond between wood and steel : B. Sc. thesisLobnik, JureV raziskavi smo proučevali kakovost epoksidnega lepilnega spoja med lesom in jeklom. Ugotavljali smo vpliv priprave površine jekla na strižno trdnost lepilnega spoja. Površine jekla so bile obdelane ... na štiri različne načine, in sicer neobdelana, grobo brušena, polirana in žlebičeno polirana površina. Za lepljenje smo uporabili dvokomponentno epoksidno lepilo Xepox 40. Lesene lamele so bile izdelane iz smrekovega lesa. Ko smo lesene in jeklene lamele zlepili in je lepilo utrdilo, smo polovico preizkušancev izpostavili standardni klimi, polovico pa smo 24 ur namakali v vodi. Nato smo opravili test strižne trdnosti po standardu SIST EN 205:2003. Po porušitvi preizkušanca smo ocenili delež loma po lesu. Ugotovili smo, da na strižno trdnost lepilnega spoja vpliva predhodna obdelava površine jekla. Med preizkušanci, ki so bili izpostavljeni standardni klimi, so najboljše rezultate dosegli preizkušanci, pri katerih je bila površina jekla polirana, medtem ko so po 24-urnem namakanju največjo strižno trdnost dosegli preizkušanci, ki so imeli neobdelano površino jekla. V splošnem je bila strižna trdnost spoja namočenih preizkušancev bistveno manjša kot klimatiziranih preizkušancev. Na osnovi rezultatov lahko zaključimo, da je dvokomponentno epoksidno lepilo Xepox 40 primerno za lepljenje lesa in jekla za uporabo v suhih pogojih.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [J.
