Bonded hybrid joints in the automotive industry
Ševčík, Jan ; Hanáčková, Pavla (referee) ; Kubíček, Jaroslav (advisor)
This diploma thesis deals with bonded hybrid joints which are used for connecting parts of modern coachwork. Firstly, the thesis describes in general the process of production of the whole coachwork, from cutting of the blanks to the surface treatment including the analysis of the used materials. Subsequently, the problem of joining body parts through adhesives, but also by welding, soldering or other methods is discussed. Another part of this thesis is dedicated to an experiment in which the qualities of bonded hybrid joints were determined. Different ways of realizing the joint have been made which differed in the size of the glued surface, in the welding methods and in the process of their creation. The produced joints were tested for their strength and quality.

Bonding in the automotive industry
Krejčí, Adam ; Hanáčková, Pavla (referee) ; Kubíček, Jaroslav (advisor)
The thesis presents a literature study of adhesive bonding technology. The work deals with the advantages and disadvantages of adhesive bonding, design of adhesive joints, technological processes of adhesive bonding and the division of adhesives. The thesis also discusses various materials used for the construction of car bodywork and their properties. The main focus of the work is on the use of adhesive bonding in the car industry, comparing traditional and modern technology used for the construction of bus bodywork. In the experimental part of the thesis, the aim is to reveal the influence of surface treatment on the resulting shear strength when employing metal to metal bonding.

Hybrid bonded joints
Godál, Samuel ; Hanáčková, Pavla (referee) ; Kubíček, Jaroslav (advisor)
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.
