Evolution from microfibers to nanofibers toward next-generation ceramic matrix composites: A review

Ceramic matrix composites (CMCs) are designed to overcome the main drawback of monolithic ceramics, namely their brittleness, and are constituently expressed as a continuous phase, or matrix, a distributed phase, commonly referred to as the reinforcing fibers, and also an interphase layer or coating layer between them. In this regard, there is a necessity to understand the principles for choosing the reinforcing fibers and designing the fiber–matrix interfaces. Hence, an attempt is made to review the recent progresses on ceramic micro-nano fibers and their effect on the interfaces in CMCs. The development trend for CMCs is discussed, especially the future CMCs based on ceramic micro-nano fibers, including the strengthening and interface construction concerning with these fibers.
