Ceramic Matrix Composites (CMCs) is classified under advanced materials that have grown significant attention in various engineering applications due to their exceptional combination of high temperature stability, mechanical strength, great corrosion resistance, and lightweight characteristics. This class of composites consists of a ceramic matrix reinforced with high-performance ceramic fibers or particles having different geometries. CMCs offer a unique set of properties that tops traditional monolithic ceramics and metal alloys. The collaborative effects between the matrix and reinforcement components contribute to enhanced thermal and mechanical performance together with having acceptable crack arrest feature, making CMCs particularly suitable for applications in aerospace, automotive, energy, and other demanding industries where parts are exposed to cyclic load and high temperature service environment.
This chapter provides an overview of the key aspects of CMCs, including their composition, fabrication methods, and unique material properties. Sol–gel infiltration approach, polymer infiltration pyrolysis approach (PIP), liquid silicon infiltration (LSI), chemical vapor infiltration (CVI), chemical vapor deposition (CVD), and powder sintering processing CMCs are fully discussed in this chapter. The challenges associated with manufacturing and processing CMCs are also discussed. In addition to their potential usage in high-temperature environments, they have reasonably acceptable fracture toughness properties due to interface crack arrest and ceramic fiber bridging mechanisms during their service operation. As demands for CMC materials continue to advance, they can play a crucial role in pushing the boundaries of ceramic composite material to various industries. Therefore, opening new possibilities for improved performance in a wide range of applications.
