Core Viewpoint - Ceramic matrix composites (CMCs) exhibit excellent high-temperature performance and have broad applications in aerospace, nuclear power, and automotive industries, with significant market potential. China leads in brake and thermal protection for aircraft but lags in aerospace engine applications. The demand for CMCs in China's aerospace industry may reach a turning point in 2024, driven by advancements in production technology and cost reductions [2][12]. Group 1: CMC Characteristics and Applications - CMCs are defined as composites that incorporate reinforcing materials into a ceramic matrix, resulting in superior properties such as high-temperature resistance, low density, and high strength [3][19]. - SiCf/SiC composites are a research focus due to their excellent oxidation resistance and longevity, making them ideal for aerospace engine applications [4][26]. - CMCs are increasingly recognized as strategic materials for next-generation aerospace engines, capable of withstanding temperatures significantly higher than traditional nickel-based superalloys [29][33]. Group 2: Market Growth and Demand - The global CMC market was valued at $11.9 billion in 2022 and is projected to grow at a CAGR of 10.5%, reaching $21.6 billion by 2028, with the highest market share in defense and aerospace sectors [5]. - The demand for CMCs in the aerospace sector is expected to surge, particularly for components like combustion chambers and turbine blades, as countries strive for higher engine efficiency and reduced emissions [32][40]. Group 3: CMC Production and Industry Landscape - The production of CMCs involves complex processes with high barriers to entry, including fiber preparation, preform weaving, interface layer preparation, and matrix densification [6][7]. - General Electric (GE) has established a vertically integrated CMC supply chain, significantly increasing production capacity and demonstrating successful applications in various engine components [6][40][41]. - China's CMC industry has developed a relatively complete supply chain, with advancements in silicon carbide fiber production and CMC applications, particularly in brake materials for aircraft [8][10][11]. Group 4: Future Investment Opportunities - The anticipated turning point in demand for CMCs in China's aerospace industry presents substantial growth potential for related companies, especially as production technologies improve and costs decrease [12][8]. - As the application of SiCf/SiC composites matures, upstream raw material demand will increase, leading to potential rapid growth for midstream CMC component manufacturers [12][10].
