Izbira lepila za izdelavo slojnatega kompozita iz bukovega furnirja : diplomski projekt = Selecting right glue to make a layer composite from beech veneer : B. Sc. thesisRajšp, AndrejCilj raziskave je bil izbrati najustreznejše lepilo za izdelavo slojnatega kompozita v obliki cevi za kasnejšo izdelavo lesenega kolesa. Ker je proces izdelave zahteven, je bila izbira ustrezne ... tehnologije in lepila ključna. Izbrali smo 3 lepila, ki naj bi ustrezala z vidika trdnosti in trajnosti, in sicer poliuretansko lepilo Mitopur E45, poliestrsko lepilo Colpoly 7201 ter epoksidno lepilo Epox 210. Najprej smo z vsakim lepilom izdelali lepljenec iz 2 bukovih lamel, iz katerih smo kasneje izžagali preizkušance za ugotavljanje natezno strižne trdnosti lepilnih spojev po standardu SIST EN 205. Pred testiranjem smo preizkušance izpostavili različnim pogojem, kot jih predpisuje standard SIST EN 12765. Ugotovili smo, da je bilo poliuretansko lepilo najprimernejše za lepljenje, saj je v vseh pripravah doseglo najboljše rezultate. Pri epoksidnem lepilu smo imeli težave s prehitro penetracijo v furnir, kar se je odražalo tudi pri rezultatih, saj so nekateri preizkušanci imeli veliko trdnost, medtem ko so nekateri razpadli že pri pripravi. S poliestrskim lepilom smo izmed vseh lepil dosegli najmanjšo trdnost spoja.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [A.
