Research status of toughening SiC composite ceramics
SiC ceramics have excellent properties and are widely used in various industries.However,the lack of toughness restricts their application as structural materials.Therefore,improving their toughness has become a research hotspot and focus.The research status of SiC composites toughened by different strengthening phases,such as particle phases,whiskers,fibers and low dimensional nano-materials(car-bon nanotubes and graphene),was reviewed,expecting to provide a reference for toughening SiC ceram-ics in the future.
