Abstract in another language

In this paper, the compatibility of different mullite-based matrix compositions for the fabrication of all-oxide ceramic matrix composites (Ox/Ox) was assessed by applying the He-Hutchinson model. Investigated factors were the mullite type, the particle size and the fine fraction. The tests were conducted on monolithic bending specimens which were fabricated by slip casting. The choice of mullite powder and its particle size had the most significant effect on the fracture energy and the Young´s modulus of the samples. For a reliable prediction of the composite failure behavior, the sample shrinkage had to be considered. Ox/Ox were fabricated to validate the predictions derived from the monolithic tests. The results were in excellent agreement with the predicted expectations for the composite failure behavior. Hence, the procedure applied in this work provided a straightforward approach to identify matrix compositions for Ox/Ox composite with highly promising properties.
