Abstract

Fibre reinforced all oxide ceramic matrix composites (oxCMC) have made significant advancements over the past 20 years and have found their way into a growing number of industrial applications. However, the material properties and quality vary considerably and depend strongly on the manufacturing process and respective processing parameters. With regards to industrial production capability, filament winding is the most automated and state-of-the-art fabrication technology for oxCMC today, in particular for rotational symmetric designs and components. Nevertheless, there is considerable potential to improve material properties and quality by technological optimization of critical processing parameters to meet the growing demands and requirements of future applications. Several key processing parameters for filament winding of oxide CMC were identified and their effect on the overall processability and resulting material properties will be presented, demonstrating a significant improvement of material homogeneity and reproducibility as well as an increase in bending strength by around 30%.
