With the comprehensive promotion of resource-saving and environmentally friendly social construction, architectural ceramics have also taken an important step in the transformation process as decorative materials. Among them, lightweighting and thinness have become the main trends in the research and development, design, production, and use of architectural ceramic products.

At present, one of the main methods for improving the failure strength and fracture modulus of building ceramics is to increase the density of the ceramics. Adding an appropriate amount of short fibers to building ceramics based on the reinforcement mechanism of composite materials is a promising method to improve their failure strength, fracture modulus, and even toughness.

In ceramic matrix composites, short fibers commonly used for matrix reinforcement include alumina, carbon fibers, and so on. Under strict firing conditions, carbon fiber can still serve as a reinforcement to form composite ceramics with silicon carbide and oxide matrices. In addition, carbon fiber can also be used to enhance oxide ceramics, but it needs to be fired in vacuum or inert gas.
