TL;DR: In this paper, an oxide-based ceramic matrix composites with a highly porous mullite matrix and Nextel™ 720 alumino silicate fibers have been fabricated by infiltrating filaments with a mullite precursor slurry, and by subsequent one-dimensional and two-dimensional winding up the fiber bundles on mandrels.
Abstract: Oxide-based ceramic matrix composites with a highly porous mullite matrix and Nextel™ 720 alumino silicate fibers have been fabricated by infiltrating filaments with a mullite precursor slurry, and by subsequent one-dimensional (1D) and two-dimensional (2D)-winding up the fiber bundles on mandrels. The green bodies were pressureless sintered in air at 1300°C. These composites which require no fiber/matrix interface are characterized by favorable damage tolerance and bending strengths of 160 MPa at room temperature and up to temperatures of 1200°C. These properties make it an excellent low-cost choice for combustion chamber liners, diffusor rings and other thermal protection systems for high temperature applications in oxidizing environment.

TL;DR: In this article, carbon-carbon, carbon-silicon carbide, and silicon carbide and silicon carbonide -silicon carbonide composites were vacuum brazed to Ti and Hastealloy X using Ni-base metallic glass braze foils (MBF-20 and MBF-30).
Abstract: Carbon–carbon, carbon–silicon carbide, and silicon carbide–silicon carbide composites were vacuum brazed to Ti and Hastealloy X using Ni-base metallic glass braze foils (MBF-20 and MBF-30). Scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) of the joints showed that compositional changes due to substrate dissolution led to secondary-phase precipitation which aided interfacial bonding although inter-laminar shear failure occurred within some composites. Residual thermal stresses in the joint led to hardness gradients; however, stress accommodation by the brazes prevented interfacial cracking. The peak Knoop microhardness in the joints was as high as 1165–1294 KHN.

TL;DR: In this article, a model is presented to estimate the reliability and time-to-failure of an unidirectional continuous fiber-reinforced ceramic composite when subjected to stresses beyond the matrix cracking stress.
Abstract: A model is presented to estimate the reliability and time-to-failure of an unidirectional continuous fiber-reinforced ceramic composite when subjected to stresses beyond the matrix cracking stress. The particular case of oxidation-assisted stress-rupture at intermediate temperatures is considered. The effects of stress and temperature on the reliability of the model composite are examined. Model predictions are presented for the specific case of CG-Nicalon™/SiC CFCCs with carbonaceous fiber coatings.
