Utilization of Nanofibres in the Traditional Ceramics Body
Sedláček, Daniel ; Stančík,, Hynek (referee) ; Sokolář, Radomír (advisor)
This thesis summarizes the current knowledge about ceramic composites with nanofibers. So far, most research focused on the reinforcement of hi-tech ceramics, such as carbides and nitrides, however, this traditional ceramics left behind. Due to the improving the efficiency of production of nanofibers and thus a drop in prices, companies consider their use even in a cheaper ceramic materials. Reinforcement of traditional ceramic shard could theoretically improve many characteristics, but there are absolute minimum of practical researches.

The present study investigates the influence of NDP on mechanical properties of multi-layer PVA nanofiber textiles. The particles of a diameter equal to 5 nm were incorporated into double- and triple-layer textiles, while the single-layer samples were prepared as the reference. The diameter of PVA nanofibers varied from 100 to 300 nm. We characterized the tensile strength, stiffness and ductility of fabricated nanofibers by using a conventional method – a tensile test. We found that the NDP-enriched nanofibers reveal antibacterial character. However, none or negligible influence of NDP additions on the tested mechanical properties was observed.
