TL;DR: In this article, failure mechanisms were studied by reflection light microscopy in a unidirectional silicon carbide/glass-ceramic composite loaded in longitudinal tension, and the results of crack density and stress/strain behavior were compared with predictions based on a modified shear lag analysis.

TL;DR: In this article, the effects of pyrolysis temperature and SiC-filler content on microstructures and properties of the composites were systematically studied, and the results showed that the failure stress and fracture toughness increased with the increase of pyrotechnic temperature.

TL;DR: In this article, a selective laser sintering (SLS) combined with cold isostatic pressing (CIP) process was used to consolidate Al 2 O 3 powder with additive of epoxy resin E06 (ER06) and polyvinyl alcohol (PVA).

TL;DR: In this article, the authors focused on Al2O3-Al composites obtained via infiltration of porous ceramics by liquid Al. This effect should be taken into consideration in designing of composites (in calculation of the amount of Al which is needed for full infiltration).

TL;DR: In this article, the interface in mullite fiber/mullite matrix composites was engineered by using thick BN (1 μm) or BN/SiC double coating on mullite fibers, such that deformation mechanisms conducive to toughness enhancement could be brought to play.
Abstract: Oxide fiber/oxide matrix composites form an important and very attractive subpart of ceramic matrix composites because of their inherent stability in oxidizing atmospheres at high temperature. In particular, mullite fiber/mullite matrix composites have the potential of high temperature usage in oxidizing atmospheres. The interface in mullite fiber/mullite matrix was engineered by using thick BN (1 μm) or BN/SiC double coating on mullite fibers, such that deformation mechanisms conducive to toughness enhancement could be brought to play. Significant improvements in the room temperature mechanical properties of these mullite fiber/mullite matrix composites could be achieved by incorporation of these interfacial coatings and by using a colloidal processing route to make dense mullite matrix.
