20.500.12556/RUL-179937 Spajanje kovinskih in polimernih komponent z dodajalno izdelanimi celičnimi zapornimi strukturami Joining of metallic and polymeric components through additively manufactured lattice interlocking structures Napredek na različnih področjih zahteva potrebo po razvoju funkcionalnejših komponent in polizdelkih. Ena od potreb je tudi spajanje kovinskih in polimernih komponent. Obravnavali smo izvedbo spoja, ki temelji na tlačnem brizganju polimera v celično strukturo izdelano z dodajalno tehnologijo selektivnega laserskega taljenja (SLT). Kot osnovna elementa celičnih struktur sta bili obravnavani BCC in BCCZ celici. Na osnovi preskusov natezne trdnosti je bilo ugotovljeno, da je z uporabo omenjenih tehnologij mogoče izdelati funkcionalni spoj. Kot naj vplivnejši parameter je bil ugotovljen premer paličja, ki vpliva na relativno gostoto mrežaste strukture in efektivni presek brizganega polimera. Pokazali smo tudi zelo dobro ujemanje teoretično ocenjene in s poskusi izmerjene natezne trdnosti spoja. Progress in various fields requires the development of more functional components and semi-finished products. One of the emerging needs is joining of metalic and polymer components. In this study, we investigated a joint based on injection molding of polymer into a ccellular structure manufactured using the additive technology of Selective Laser Melting (SLM). As the basic elements of the cellular structures, BCC and BCCZ unit cells were considered. Based on tensile strenght tests, it was found that the use of the mentioned technologies enables the production of a functional joint. The most influential parameter was identified as the strut dimeter, which affects the relative density of the lattice structure and the effective cross-section of the injected polymer. We also demonstrated very good agreement between the theoretically predicted and experimentally measured tensile strenght of the joint. dodajalna tehnologija SLT premer paličja mrežasta struktura kovinsko-polimerni spoji tlačno brizganje polimerov relativna gostota natezni preizkusi mehanske lastnosti spoja SLT additive manufacturing technology strut diameter lattice structures metal-polymer joints polymer injection molding relative density tensile strenght mechanical properties of tne joints true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-02-27 08:30:35 2026-02-27 08:30:38 2026-03-03 13:35:29 0000-00-00 00:00:00 2026 0 0 XX, 59 str. 2026 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 539.2:620.172(043.2) 283272 270294275 46590.pdf 46590.pdf 1 5398DDDAA8EBF570ECCF866D1E02972A 091fd3db5c54889a4386c0a321c0ab99782fa64d7e16fe36deb517ab8cf60ebc e228321e-13ad-11f1-a1ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=228877 Fakulteta za strojništvo 0 0 0
