Comparison of the mechanical hysteresis of carbon/ceramic-matrix composites with different fiber preforms Original Research Article

The mechanical hysteresis of four ceramic matrix composites with different carbon fiber preforms, i.e. needled C/SiC, 2D C/SiC, 2.5D C/SiC, and 3D C/SiC, was investigated and compared during cyclic reloading–unloading tests. An effective coefficient of th
