Uporaba polimernih kompozitov v ladjedelništvu : zaključna naloga Razvojno raziskovalnega programa I. stopnje StrojništvoŠkrlj, Vesna, strojnicaPolimerni kompoziti se v ladjedelništvu uporabljajo že dobrega pol stoletja, saj omogočajo gradnjo bolj ekonomičnih in trajnejših plovil. Kompoziti imajo mnoge prednosti ter tudi nekaj ... pomanjkljivosti. Ena od večjih pomanjkljivosti polimernih kompozitov je gorljivost, ki smo jo v predstavljeni nalogi testirali na izbranih materialih na podlagi standarda UL 94 % horizontalni test. Za testiranje smo izbrali dve epoksi smoli z visoko temperaturo steklastega prehoda, katerima smo dodajali zaviralec gorenja, aluminijev hidroksid. Po testiranju smo prišli do ugotovitve, da se večja koncentracija zaviralca gorenja odraža v boljši odpornosti na gorenje. Z večanjem vsebnosti aditiva smo dosegli nižjo hitrost gorenja in manjšo količino zgorelega materiala. Aditivi prav tako vplivajo na mehanske lastnosti materialov, zato smo pri proučevanih vzorcih izvedli natezni test, čigar rezultati so pokazali, da se togost in krhkost smole načeloma povečujeta z večanjem vsebnosti aditiva. Kljub izbiri materiala z visoko temperaturo steklastega prehoda in dodatku zaviralca gorenja zaenkrat pri uporabi proučevanih polimernih kompozitov še ne moremo zagotavljati enake požarne varnosti, kot jo zagotavlja jeklo.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [V.
