TLDR
In situ fiber fracture characteristics have been investigated for Si-Ti-C-O fibres after tensile testing up to 1380°C in vacuum and in air as mentioned in this paper, and the results indicated that fibres tested in air at elevated temperature have significantly lower strengths and average Weibull parameter, m, compared to the room-temperature, 1200 and 1300°C/vacuum cases, and this is attributed to oxygen damage of the fibre together with oxidation of the fiber/matrix interface.About:

High-velocity impact damage behavior of plain-woven SiC/SiC composites after thermal loading
TL;DR: In this article, the authors investigated the impact properties of plain-woven SiC/SiC composites after thermal loading and found that an oxide layer was generated on the specimen surface by thermal loading at 1000°C and brittle failure occurred due to oxidation of the fiber/matrix interfaces.

Crack deflection at an interface between dissimilar elastic-materials
M.Y. He,John W. Hutchinson +1 more
TL;DR: In this paper, the authors examined the competition between deflection and penetration when the materials on either side of the interface are elastic and isotropic and determined the range of interface toughness relative to bulk material toughness which ensures that cracks will be deflected into the interface.

Theory of mechanical-properties of ceramic-matrix composites
TL;DR: In this article, the pullout lengths, work of pullout, and ultimate tensile strength of CMC composite materials were predicted as a function of the underlying material properties, including the fiber radius and fill fraction, and the sliding resistance-tau between the fibers and the matrix.
