Abstract
Fiber/matrix interfaces play a key role in determining the mechanical properties of fiber-reinforced ceramic matrix composites (CMCs). In this chapter, after a brief overview of recent developments and applications of microfiber-reinforced and nanofiber-reinforced CMCs, there is a theoretical analysis of the composites that exhibit the three most important behaviors associated with toughening in fiber composites: crack deflection at the fiber/matrix interface, crack bridging by the fibers, and fiber pullout on the crack plane. Approaches for controlling interfacial behavior and the interphase to optimize the mechanical and thermal properties of the composites are discussed.
