Summary

The decline in strength of Si-M-C-O/SiC composite materials in a high-temperature environment is attributed mainly to the decline in fiber strength due to the thermal decomposition and crystallization of the Si-M-C-O fiber. Decomposition and oxidation characteristics of Si-Ti-C-O and Si-Zr-C-O fibers with different oxygen content (Tyranno LoxM, LoxE, ZMI, and ZE) were evaluated by weight change, XRD, and SEM observation. For the Si-Zr-C-O fiber, Extended X-ray Absorption Fine Structure (EXAFS) analysis using synchrotron radiation was applied to evaluate the decomposition resistance.
