Primerjava mehanskih lastnosti ultrazvočno zvarnih spojev iz polimera PSU GF30Oražem, Gregor, 2000-Dandanes je uporaba polimernih materialov zelo priljubljena, pri njihovi uporabi pa se pogosto srečujemo z različnimi tehnikami spajanja. Ena izmed zelo razširjenih oblik spajanja polimernih ... materialov je ultrazvočno varjenje, ki je zelo razširjeno na vseh področjih, kjer se uporabljajo polimeri, kot na primer pri izdelavi igrač, raznih ohišij strojnih delov, pakiranju v prehranski industriji itd. V zaključni nalogi smo se osredotočili na analizo termoplastičnega polimera PSU GF30. V prvem delu eksperimentalnega sklopa smo analizirali mehanske lastnosti osnovnega materiala, izrezanega iz plošče v smeri ekstrudiranja in prečno na smer ekstruzije. V drugem delu smo varili plošče v prekrivnem spoju z ultrazvočnim varjenjem. Pri tem smo spreminjali tehnološke parametre, kot sta globina uvaritve in velikost prekritja plošč. Ugotovili smo, da imajo vzorci, izdelani vzporedno na smer ekstruzije, 50 % višjo strižno trdnost kot vzorci, razrezani pravokotno na smer ekstruzije. Najboljše trdnostne lastnosti smo dosegli pri najmanjšem prekrivanju in najmanjši globini posedanja, pri čemer je bila porabljena manjša količina energije.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [G.
