Due to their high specific strength at elevated temperatures and resistance to oxidative environments, SiC-based fibers are of great interest for the reinforcement of ceramic matrix composites. They are however subjected to a slow crack growth (SCG) phenomenon causing their delayed failure under subcritical conditions. The testing of filaments, other than comprising handling difficulties, requires large sets of data (broadly dispersed), drawback alleviated by multifilament tow testing. The data available in the present paper correspond to a comprehensive mechanical characterization and static fatigue testing of various types of SiC-based fiber bundles. The initial non-linearity of load displacement curves were analyzed to reveal the tow structure originating from filament misalignment. Static fatigue tests were used to assess the lifetime prediction coefficients and its distribution parameters. These data may found interest for the interpretation of dispersion bundle testing can highlight under different solicitation mode. Such data are also prominent for the wealth of composite design and to guaranty long term performances over the broad application field offered.

“…Two different batches of NL100 (NL101 and NL102) and TS (TS and TS11, with 8.5 and 11 µm respective diameters) were characterized, bringing to 13 the total number of fiber types. Their chemical compositions can be found in the corresponding works [1] and [13] . Some chlorinated tows were also examined.…”

“…These samples were desized by heat treatment at 650 °C for 10 min in air followed by thin silica film removal in 10 vol.% hydrofluoric acid bath for 4 min, dried and then treated under pure chlorine at intermediate temperature. Treatments, with duration and temperature dependent on substrate type [13] , resulted in a homogeneous surface transformation into a carbide derived carbon phase [8] erasing or blunting surface located flaws [2] .…”
