Abstract: [slo] [eng]
V praktickej časti tejto bakalárskej práce bolo vyrobených 5 nitových spojov s polodutými lisovacími nitmi. 3 vzorky s lepeným spojom za použitia lepidla Sikaflex-222i UV a 5 hybridne lepených spojov s využitím polodutých lisovacích nitov a lepidla Sikaflex-222i UV. Všetky spojované plechy boli z materiálu AlMg1. Výsledky ťahových skúšok ukázali, že zaťaženiu najlepšie odolávali nitované vzorky. Lepené vzorky nedosiahli požadovanú odolnosť voči zaťaženiu, pretože lepidlo nemalo správnu priľnavosť k podkladu. Hybridné lepené spoje, taktiež nedosiahli požadovanú kvalitu. Bolo to z dôvodu odstrihnutia dna spoja lisovacím nitom a vznikom adhézneho lomu. In the practical part of this bachelor thesis, 5 threaded joints were made with semi-rigid pressing threads, 3 samples with glued joint using Sikaflex-222i UV adhesive and 5 hybrid bonded joints using semi-rigid pressing threads and Sikaflex-222i UV adhesive. All the bonded sheets were made of AlMg1. The tensile test results showed that the load was best resisted by the riveting samples. Adhesive samples did not achieve the required load resistance because the adhesive did not have the correct adhesion to the substrate. Hybrid glued joints have also not reached the required quality. This was due to the cutting of the bottom of the joint with a pressing thread and the formation of an adhesion fracture.
