Bonding of composite materials in precise applications
Schubert, Vojtěch ; Zouhar, Jan (referee) ; Kupčák, Radim (advisor)
This work is focused on the bonding of composite materials. Related research dealing with technology of production and bonding of these materials was additionally conducted. Practical part of this thesis was set to find out what the optimal bond line thickness was for the bonding of the composites. Thus, the strength of single-lap joints (SLJ) in series of various bond line thicknesses was therein tested. A model of samples (and design of their production by wet lay-up) for the experiment is also provided in this thesis.

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.

Study of adhesive penetration into the wood cell wall
Janová, Petra ; Krbila, Jaromír (referee) ; Vaněrek, Jan (advisor)
This labor is based on penetration of adhesive into a wood cell walls. It focuse on adhesives basicly used for construction purposes, especially on epoxy resins. The labor contains the use of methods for precise detection adhesive in wood and methodics for choice of adhesive and wood basically used for bonding. It describes the experimentally detected dependence of contact angle on viscosity epoxy resins.

Durability of glued joints of structural timber elements
Mlčák, Tomáš ; Vejpustek, Zdeněk (referee) ; Vaněrek, Jan (advisor)
This bachelor thesis deals with the topics of durability of glued connections of structural wooden elements. The theoretical part of the work deals with the construction of wood, selected defects of wood, a description of carpentry joints and fasteners. The work also pays attention to adhesives and sealants used in glued joints of wooden structures or the issue of crack repair systems in wood. The practical part of the work is focused on experimental verification of the durability of used adhesives and sealants for glued carpentry elements.

Precise bonding of composite materials
Tellinger, Adam ; Gregor, Lukáš (referee) ; Kupčák, Radim (advisor)
This bachelor's thesis deals with the issue of bonding composite materials. The first part of the bachelor's thesis is focused on research into the production of composite materials and gluing technologies. The content of the practical part is the design of test specimens and a preparation for their bonding with subsequent production. Furthermore, verification of compliance with the required accuracy of bonded joints when using different adhesives using 3D measurements.

Implementation of optical fibers with FBG elements into technical textiles
Zaytsev, Vsevolod ; Dejdar, Petr (referee) ; Münster, Petr (advisor)
(This bachelor thesis aims at a theoretical analysis of \acs{FBG} (\acl{FBG}), its use in telecommunications technology and the design of smart textiles based on FBG filters. The theoretical part of this work discusses the knowledge of FBG, their production and use, presents an overview of technical textiles and the current state of the market. Then the question of adhesive adhesives will also be described. The practical part is devoted to the design of smart textiles and the subsequent measurement of the dependence of the wavelengths of the built-in FBGs on their temperature.)

Bonding of 3D printed PET-G parts
Maxa, Ondřej ; Kupčák, Radim (referee) ; Zemčík, Oskar (advisor)
This bachelor thesis solves the problem of gluing PET-G material, which is used for printing 3D models in 3D printers. The goal is to select and then test the adhesive suitable for bonding the material. The suitability of the recommended adhesives was determined on the basis of standardized tests on experimental blasting equipment. Based on the measurement results, it is suitable to use one-component instant adhesives for gluing PET-G material, the advantage of which is easy handling and quickly achievable handling strength.

Bonding of composite materials in precise applications
Hartmann, Kurt ; Gregor, Lukáš (referee) ; Kupčák, Radim (advisor)
A study on composite materials and adhesive technology was conducted as part of the research. The main objective of the work was to evaluate the suitability of selected adhesives for precision applications. The practical part focused on this objective and included the design and development of a special bonding preparation, enabling the creation of samples for subsequent strength testing.
