Continuous SiC fber-reinforced SiC composites

Time:2019-07-23 15:33:08  From:  Author:

 Continuous SiC fber-reinforced SiC composites (SiCf/SiC) are the leading candidate for structural components in future fusion and advanced fssion reactors. This potential application is driven primarily by the low induced radioactivity and good resistance of SiC under neutron irradiation . On the other hand, the fabrication of damage-tolerant SiC-based composites is eclipsed by their inherent covalent and brittle nature, which poses a major challenge to the scientifc community. One of the basic premises in developing SiCf/SiC composites with sufcient workable toughness is to facilitate a mechanically ‘weak’ interphase on rigid SiC fbers . This ‘weak’ interphase can impart toughness by triggering a range of energy dissipation mechanisms, such as interfacial debonding, fber pullout, and crack deection . Another concurrent challenge to be addressed is the inferior mechanical properties exhibited by SiCf/SiC, such as the exural strength and fracture toughness.
