The aim of the master thesis is to research liquid metals, or research on the influence of the selected particulate filler to selected mechanical properties that characterize the use of liquid metals for renovation of machine parts or assembly parts, two-component reactive adhesives based on epoxy resin, with a partial aim to assess and select the optimal amount added . In this master thesis are interpreted measured values for each of the fillers that are in discussion compares the results of other research papers. In the last part of master thesis is done techno-economic evaluation.

The thesis is focused on research of polymer composites with natural fibers. The theoretical part is an introduction to composite materials with a focus on natural fiber reinforcements and polymers. For the needs of the experimental part of the work also deal with theoretical issues of bonded joints. Experimental part deals with the influence of natural substances added to the bond formed polymeric adhesive and the resulting composite. Made composites were tested and evaluated from the mechanical and technological-economic terms.

This work is about relation between material and technology for developing specific product used in field of sport equipment. Designed was mast or hydrofoil for kiteboarding. Basic part is about terminology, history, physical principle and actual market research. Next topic is related whit material selection, where is best choice carbon fiber reinforced composite. A description of composites goes from general information to specific steps in technology. Author describes practical experiences whit exclusive autoclave technology and also other methods. In practical part was prepared three prototypes whit deferent composition and technology. Core and moulds was made from wooden based materials which ware manufactured in three dimensions whit CNC machine. Fist prototype was laminated only on core, second used sandwich construction in mould and third combines these two methods.

Theoretical part describes conventional types of swingarm, provides basic introduction to composites and manufacturing technologies. Practical part describes production steps, assembly jigs and assembly process. The last part of thesis deals with measuring stiffness properties using photogrammetry system TRITOP.

The subject of the diploma thesis is the study of moisture resistance of macrodefect-free (MDF) cements based on calcium-aluminate cement and polyvinylalcohol used as polymer. MDF cements are perspective materials providing unique properties relative to traditional cement pastes with great potential to incoming constructional utilization. But it is known that MDF cements exhibit sensitivity to water, with swelling and reduction of strength. Therefore the work is aimed in monitoring of an organic polymer effect on the moisture resistance of MDF materials and phase changes. Aluminate cement (SECAR 51) and polyvinylalcohol/acetate copolymer have been used for the MDF cement preparation. The moisture resistance of model MDF cement samples was investigated at two different curing conditions: in the moist atmosphere and immersed in water. The influence of composition and individual curing on the properties of model MDF cement samples was observed. The characterization of MDF samples was based especially on test of flexural strength, FT-IR, EDAX and optical microscopy analyses.

This masters’s thesis study electric properties of nanocomposites based on epoxy resins, production of samples and measuring their electrical properties. In this thesis there are observed temperature dependences of the dissipation factor, relative permittivity and internal resistivity.

The diploma work is focused on the development and analysis of plywood material reinforced by means of synthetic fibers, namely on its mechanical properties in a three – point bend in compliance with the CSN EN 310 Standard in comparison with the conventional plywood. At first, the mechanical properties of the material were simulated with the aid of a computer-aided model on the basis of the classical laminate theory and then compared to the real measured values. In addition to it, the influence of preloaded fibers on the mechanical properties of the composite was examined. To preload the fibers, two simple fixtures were manufactured. The analysis of variance and the Tukey’s test of multiple comparison demonstrated important differences in the resistance and rigidity of the plywood material both with the reinforcement and without it. The highest resistance proved the plywood samples without any reinforcement (at an average of 153.9 MPa), the highest rigidity was achieved in samples with reinforcement without any preloading (at an average of 29374.4 MPa).
