TL;DR: In this paper, a model describing the salient features of tensile stress-strain curves of ceramic-fiber composites has been developed, which incorporates statistics of fiber failure.
Abstract: A model describing the salient features of tensile stress-strain curves of ceramic–fiber composites has been developed. The model incorporates statistics of fiber failure. Furthermore, the compliance of the testing machine is included so that the onset of instability can be predicted. An experiment conducted on a composite consisting of a glass-ceramic matrix reinforced with SiC fibers exhibits excellent agreement with the predicted behavior.

TL;DR: In this paper, multilayer ytterbium-hafnate/silicate coatings deposited by directed vapor deposition and designed to protect SiC-based ceramic matrix composites were assessed to determine their thermochemical stability and resistance to attack by molten silicate deposits.
Abstract: Multilayer ytterbium-hafnate/silicate coatings deposited by directed vapor deposition and designed to protect SiC-based ceramic matrix composites were assessed to determine their thermochemical stability and resistance to attack by molten silicate deposits (CMAS). The study revealed that reactions occurring at the interface between Yb2Si2O7 and Yb4Hf3O12 layers promote coating delamination following isothermal annealing for 100 h/1500°C while coating architectures involving Yb2SiO5 in contact with Yb4Hf3O12 do not experience similar degradation. The outer Yb4Hf3O12 layers, segmented for compliance, were only moderately effective in mitigating CMAS infiltration at 1300°C and 1500°C. The results indicate that the reaction between the melt and coating forms large volumes of a silicate garnet phase at 1300°C, or a cuspidine-type aluminosilicate at 1500°C, in addition to the apatite and reprecipitated fluorite phases observed in related systems.

TL;DR: In this paper, the microstructure and damage tolerance mechanism of Ti3SiC2 was investigated, and the result demonstrated that the Ti3 SiC2 ceramics prepared by the in-situ hot pressing/solid-liquid reaction process had a dual micro-structure, i.e., large laminated grains were distributed within small equiaxial grains.
Abstract: Titanium silicon carbide (Ti3SiC2) is a damage tolerance material that is expected to be used in a number of high temperature applications. In this work, the microstructure and damage tolerance mechanism of Ti3SiC2 was investigated. The result demonstrated that the Ti3SiC2 ceramics prepared by the in-situ hot pressing/solid-liquid reaction process had a dual microstructure, i.e., large laminated grains were distributed within small equiaxial grains. This microstructure is analogous to that of platelets reinforced ceramic matrix composites. The bending test using single-edge-notched-beam specimens revealed that Ti3SiC2 was a damage tolerance material. The damage tolerance mechanisms for Ti3SiC2 are basal plane slip, grain buckling, crack deflection, crack branching, pull-out and delamination of the laminated grains.

TL;DR: In this article, the change in mechanical properties of a fiber-reinforced ceramic from room temperature to notch sensitivity at elevated temperature has been investigated and attributed primarily to a correspondingly large variation in the shear resistance of the fiber/matrix interface caused by oxidation effects at that interface.
Abstract: The change in mechanical properties of a fiber-reinforced ceramic from notch insensitivity at room temperature to notch sensitivity at elevated temperature has been investigated. The change in behavior has been attributed primarily to a correspondingly large variation in the shear resistance of the fiber/matrix interface caused by oxidation effects at that interface. The transition in behavior has been correlated with a fracture model based on the incidence of fiber failure in the crack wake.
