Characterization of Tensile Damage for 3D-C/SiC Composites by Acoustic Emission Yan-jun CHANG1, 2, a, Ke-shi ZHANG1, b , Gui-juan HU 1, c , Gui-qiong JIAO2, d 1College of Civil Engineering & Architecture, Guangxi University, Nanning 530004, China 2 School of Mechanics and Civil Construction, Northwestern Polytechnical University, Xi' an 710072, China a yanjun_chang@126.com, bzhangks@gxu.edu.cn, chgj1973@sina.com, djiaogq@nwpu.edu.cn Key words: C/SiC composites; damage evolution; cluster failure; Felicity effect Abstract: The various damage mechanisms in 3D-C/SiC composites are identified using acoustic emission (AE) signal parameters, and the Felicity effect is studied on different unloading stress.
Therefore, Felicity ratio may be more suitable to reflect the damage level, for 3D-C/SiC composite materials, the stress that 60% of strength is proposed as the engineering design value of strength.
