Analysis of the influence of cellulose fibers in epoxy adhesive designed for wood structural elements bonding
Dvořáková, Martina ; Tupý, Michael (referee) ; Vaněrek, Jan (advisor)
The thesis deals with the properties of epoxy resins, their reinforcing by thermoplastic modified epoxies, rubbers and cellulose fibers. The thesis also describes the production, properties and types of cellulose fibers. In the practical part of this thesis, there was executed reinforcement of epoxy matrix by different amounts of cellulose fibers. Mixing was performed in two ways – by a homogenizer or an ultrasonic homogenizer. There were also executed the tensile strength and shear strength tests to the manufactured conglomerates.
Properties of pultruded composites based on epoxy matrix
Huljak, Pavel ; Bálková, Radka (referee) ; Přikryl, Radek (advisor)
The theoretical part of this bachelor thesis deals with research of composite materials, especially based on polymer epoxy and polyester resins, using as reinforcement a glass fiber bundles. The practical section includes the production of composite materials and their components along with the most important testing methods. The main goal of the experimental part is to characterize the optimal conditions pultrusion production of epoxy composite material. Another point is characterization of mechanical and chemical properties of the produced composite at a number of test methods. Finally the optimized epoxy composite materials are compared with composites based on polyester resins.
Polymer matrix based on epoxydized oils
Kvasničková, Lucie ; Tocháček, Jiří (referee) ; Přikryl, Radek (advisor)
The theoretical part of this bachelor thesis deals with a current state in the field polymer matrix based on vegetable oils and their epoxidation. Subsequently it deals with epoxy resins – particularly their structure, crosslinking and a curing. The experimental part of this research focuses on the amine curing of epoxy resins. A curing of epoxidized soybean oil with various amine curing agents was tested and also a curing of a blend containing comercial epoxy resin and epoxidized soybean oil. Testing pieces were prepared from selected mixtures and a tensile test was performed on them.
