摘要：

In situ fibre strength Weibull parameters and fibre pullout length distributions were investigated for a 3D woven SiC/SiC-based composite with glass sealant oxidation protection system after tensile testing at 1000 degrees C and 1200 degrees C in air. Results were similar to those previously observed for unsealed specimens tested in vacuum (1200-1380 degrees C), but significantly different from the case of unsealed specimens tested in air (1100-1200 degrees C). Overall, it was concluded that the glass sealant provided excellent oxidation protection for the composite at the test conditions employed, i.e. short-term exposure up to 1200 degrees C in air.
