| Description
| - Degradation process and influence of metal particles (Cu, Fe, CuZn) on the stability of acid catalyzed (novolak) phenolic resin during curing and friction process in friction composites have been studied. Using TGA, FTIR and Py-GC methods, the significant influence of copper and iron chips, in case of high metal concentrations, on degradation process during curing of novolac phenolic resin has been found. The same behavior was confirmed for friction process. It follows that copper and iron can act as catalysts and therefore the model mechanisms for metal catalysis were proposed. The key role in the phenolic resin degradation process belongs to the elimination of formaldehyde, as an important curing agent, caused by metal and metal oxide catalysis. Brass (CuZn) does not influence the stability regardless of concentration but the wear characteristics after friction process of brass containing samples were extremely high if compared to other ones. Brass influence is rather physical as chemical owing to f

- Byl zkoumán degradační proces a vliv kovových částic (Cu, Fe,CuZn) na stabilitu fenolycké pryskyřice (novolak) během frikčního procesu ve frikčních kompozitech.Ve vzorcích s vyskou koncentrací kovových částic byl za pomocí TGA, FTIR a Py-GC zjištěn zásadní vliv měděných a železných částic na degradační proces fenolyckých pryskyřic. Stejné chování bylo zaznamenáno pro frikční proces. (cs)
