Možnost izdelave lepljenega kompozita iz bambusa : diplomsko delo - univerzitetni študij = Potential of making a glued bamboo-based composite : graduation thesis - university studiesBoltar, LukaRaziskovali smo primernost bambusa Phyllostachys vivax za izdelavo lepljenih kompozitov. Bambus smo nabrali v zaselku Pristava pri Novi Gorici. Pretežen del raziskovalnega dela smo posvetili ... raziskovanju interakcije med lepilom in bambusom. Kakovost lepljenja smo ovrednotili z merjenjem kontaktnega kota, strižnim testom lepilnega spoja in merjenjem efektivne globine penetracije lepila. Kontaktni kot fenol-formaldehidnega (FF) lepila smo ugotavljali s tenziometrom po Wilhelmy-jevi metodi. Strižno trdnost FF lepilnega spoja smo ugotavljali po standardu SIST EN 302-1 (2004). Efektivno globino penetracije FF lepila smo izmerili s pomočjo mikroskopa in osebnega računalnika s programom Image-Pro Plus 6.0. Ugotovitve iz teh raziskav smo nato preverili pri izdelavi lepljenega kompozita iz bambusa, iz katerega smo izdelali preizkušance za ugotavljanje mehanskih lastnosti. Modul elastičnosti in upogibno trdnost smo določili z upogibnim testom po standardu SIST EN 310 (1993). Ugotovili smo, da so bili kontaktni koti FF lepila na sveže zbrušenih bambusovih površinah zelo visoki. V primerjavi z rezultati predhodnih testiranj uporabljenega lepila smo dosegli visoke strižne trdnosti lepilnega spoja. Efektivna penetracija FF lepila v bambus je bila zelo plitva. Izdelan lepljen kompozit, slojnata bambusova plošča, je izkazoval visok modul elastičnosti ter visoko upogibno trdnost. To pomeni, da lahko iz proučevanega bambusa s pomočjo FF lepila izdelamo kvaliteten lepljen kompozit.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [L.
