Strižna voljnost polimerno kovinskih kompozitov z visokim deležem kovinskih delcev : magistrsko delo magistrskega študijskega programa II. stopnje StrojništvoMartinčič, Janez, 1994-Značilni lastnosti polimerov, kot sta enostavnost predelave in majhna specifična teža, je mogoče združiti z edinstvenimi lastnostmi polnil, ki izboljšujejo nekatere pomanjkljivosti polimerov, kot sta ... relativna nizka trdnost in togost, z dodajanjem kovinskih delcev pa lahko vplivamo tudi na termične, električne in magnetne lastnosti polimerov. Cilj magistrskega dela je preveriti, kako različni deleži in vrsta kovinskih delcev vplivajo na strižno voljnost kovinsko polimernih kompozitov na primeru polipropilenske matrice in sferičnih kovinskih delcev z masnim deležem več kot 30 %. Magistrsko delo vključuje pripravo vzorcev z različnimi deleži kovinskih delcev (Al in Ti), meritev strižne voljnosti pri različnih temperaturah in uporabo časovno-temperaturne superpozicije za napoved vedenja materialov v daljšem časovnem obdobju. Analiza rezultatov je pokazala, da se s povečevanjem koncentracije delcev v kompozitu vrednost strižnega modula voljnosti zmanjšuje, s povečevanjem koncentracije pa se zmanjšuje spreminjanje vrednosti modula voljnosti s časom - manjša časovna odvisnost. Kompozit ima tako boljšo časovno obstojnost v primerjavi z osnovnim polimernim materialom.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [J.
