Studium mechanickych vlastnosti uhlikovych kompozitu.

Carbon-carbon composites made in the USMH in Prague and testing their mechanical properties are the subjects of the dissertation work. The original purpose was to use these composites for medical objects as replacements of fixing bones directly in human tissues. In the theoretical section there are described the production and properties of carbon fibres, textile reinforcements from carbon fibres, production and properties of C - C and C -P composites and their practice use. In the experimental section there are described the concrete samples of C - C and C - P composites, their production and the results of their testing. These composites are compared from the view of their mechanical properties resulting from the measurings and from the view of propriety of the used textile reinforcements. The measuring values of mechanical properties of a C - C composite are very low in comparison with the measuring values of tested C - P composites and of foreign C - C composites. In the discussion the measuring values are compared with the values calculated from the theory of composites and a hypothesis about degradation of carbon fibres caused by high manufacturing temperatures during the production of C - C composites is pronounced.Available from STL Prague, CZ / NTK - National Technical LibrarySIGLECZCzech Republi
