- •
The cyclic loading-unloading-reloading hysteresis loops of C/SiC with different fiber preforms at room and elevated temperatures in air atmosphere have been investigated.
- •
The hysteresis loops models were used to predict the hysteresis loops corresponding to different fiber preforms, peak stresses and test conditions.
- •
The interface slip cases between fibers and the matrix would be affected by the fiber volume fraction in the loading direction, oxidation at elevated temperature and stress levels.
