PRODUCTION OF HIGH SOLID CONTENT POLYMER/YSZ COMPOSITES AND FREE FORM YSZ FIBERS
With 65 wt% solid content, Polymer/YSZ composites have been produced via extruder by using of PP, PMMA and TPU. With pyrolysis process, physical stability conditions of continuous YSZ free form fibres have been investigated according to type of polymer and pre-sintering temperature. In addition to this, melt flow rate values and thermal analysis investigations of PP, PMMA, TPU, PP/YSZ, PMMA/YSZ, TPU/YSZ were determined by melt flow rate analysis and TGA. Compared to unreinforced polymers (PMMA, PP and TPU) the melt flow rate of the composites containing YSZ powder has decreased approximately 15 %. From TGA results it was also found that the contribution of the yttria stabilized zirconia changed the decomposition temperature of the polymer part.
