20.500.12556/RUL-142757 Izdelava naprave za natezni preizkus za majhne obremenitve Construction of a tensile tester for light loads Pri razvoju in izdelavi biorazgradljivih polimernih filamentov se pojavljajo problemi s premajhno trdnostjo in krhkostjo materiala. Vse izdelke je potrebno testirati, da se lahko optimira parametre izdelave. Kot podpora izdelavi biorazgradljivih materialov smo v sklopu dela zasnovali in izdelali manjšo napravo za natezni preizkus, ki bo na voljo pri izdelavi filamentov. Za osnovo je bila vzeta kovinska konstrukcija odslužene naprave za merjenje hrapavosti. Izdelali smo sistem za merjenje sile z merilno celico in raztezka s kamero. Izvedli smo natezne preizkuse na filamentih ter natisnjenih epruvetah in preverili ali sistem ustreza standardu ISO 527, ki določa pravila za merjenje nateznih lastnosti plastik. In the development and production of biodegradable polymer filaments, problems arise with insufficient strength and fragility of the material. All products must be tested in order to optimize the manufacturing parameters. To support the production of biodegradable materials, we have designed and produced a small device for tensile testing, which will be available during the production of filaments. The metal structure of roughness measuring device, which was no longer in use, was taken as the basis. We made a system for measuring force with a measuring cell and elongation with a camera. We performed tensile tests on filaments and printed tubes and checked whether the system complies with the ISO 527 standard, which defines the rules for measuring the tensile properties of plastics. natezna trdnost polimeri računalniški vid merjenje raztezka merjenje sile naprava za natezni preizkus tensile strength polymers computer vision measuring strain measuring force tensile testing device true false false [M.
