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.

Composites based on natural fibers
Hahn, Filip ; Poláček, Petr (referee) ; Přikryl, Radek (advisor)
The theoretical part of this bachelor thesis deals with current state of art in the field of composite materials based on natural fibers and polymer matrices, and with production methods of the composite materials. The practical part focuses on the testing of the mechanical properties of sisal and flax fibers and on their chemical treatment by NaOH solution. The above mentioned fibers and unsaturated polyester resin were used to produce composite materials by means of pultrusion process. The flexural properties of the material samples were tested and compared to those of glass fiber composites.

Properties of Fiber Reinforced Plastics
Jastrzembská, Alena ; Petránek, Vít (referee) ; Bodnárová, Lenka (advisor)
This thesis deals with the theoretical part of raw materials, production and properties of composite materials with fiber reinforcement and polymer matrix. It also gives a brief overview of selected prominent Czech and foreign producers of composite materials with polymer matrix and fiber reinforcement. The practical section deals with testing the durability of selected composite profiles immersion in aggressive environments and testing of compressive strength.
