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.

Effect of surface on bonded joint
Trhoň, Vojtěch ; Halamík, Tomáš (referee) ; Kubíček, Jaroslav (advisor)
This master’s thesis is divided into two parts. In the first part are these topics: bonding theory, treatment of bonding surface, types of adhesives, adhesives in the transportation industry and construction and stress of bonded joints. In the second part of this thesis is experimental evaluation of the effect of surface of material on strength of bonded joint.

Bonding of thin metal sheets
Poul, David ; Kubíček, Jaroslav (referee) ; Dvořák, Milan (advisor)
Bachelor thesis is focused on theory and methods of adhesive bonding. Experimental part is focused on two topics: determining dependences of bonded joint shear tension on a cure time and determining dependences of bonded joint shear tension on a size of contact area. Loctite SI 5399 RD acetoxy silicone one component glue was used for these experiments. At determining dependences of bonded joint shear tension on a size of contact area tension is raising, but the grow wasn’t directly proportional on the grow of size of contact area. Determining dependences of bonded join shear tension on a cure time it was proved, that tension is raising first 24 hours very quickly. After this period is process slowing down and tension is increasing to its maximum. After 18 hours bond tension is solid enough to be handling, but 24 hours of curing time is more secured.

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.

The study of adhesion of glued balistic composites on the dependence of materials used.
Dobiáš, Jiří ; Másilko, Jiří (referee) ; Šiler, Pavel (advisor)
The aim of this work was to investigate the properties of bonded ballistic materialsBalistic composites are mainly glued to reduce weight while keeping their protective properties. On this basis, the materials used were ballistic steel, ceramics, rubber kevlar, non-gummed kevlar, Dyneema and fiberglass. For bonding used were a one-component adhesive Collano 36.104 and two-component adhesive Biresin U1305. The strength of the joint was measured in shear at tensile loads. From these results, deformation energy was further calculated.

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.
