Beschreibung
Zusammenfassung:The invention relates to ZrO2-reinforced mullite fibers having a content of at least 0.1 wt. % of crystalline ZrO2, said mullite fibers being distinguished by significantly improved mechanical properties compared to unmodified mullite fibers. The invention further relates to processes for manufacturing such fibers, green fibers produced as an intermediate product in the process, and the use of the ZrO2-reinforced mullite fibers in fibre-matrix composite materials.
