Core Viewpoint - The global commercial aerospace market is experiencing unprecedented growth, with projections indicating a market size of $75-125 billion in 2024 and expected to reach $140 billion in 2025. China's commercial aerospace market is particularly rapid, projected to reach 2.3 trillion RMB in 2024, a year-on-year growth of 22.9%, and expected to exceed 2.8 trillion RMB in 2025. Material technology is becoming a core factor determining the competitiveness of commercial aerospace companies [1]. Group 1: Material Demand Characteristics - The demand for materials in commercial aerospace differs significantly from traditional aerospace, focusing on lightweight materials to reduce launch costs, with savings of approximately 20,000-30,000 RMB per kilogram of payload. The core logic for material selection is "lightweight equals increased energy, temperature resistance equals increased efficiency, and reliability equals cost" [1]. - Breakthroughs in reusable technology require materials to withstand over 100 uses and extreme temperature ranges from -270°C to 3000°C, as well as complex space environments [1]. Group 2: Overview of Key New Materials - A total of 128 new materials have been identified as critical for commercial aerospace applications, including aluminum-lithium alloys, titanium alloys, stainless steel, high-temperature alloys, and various composite materials [3][4]. - Key materials such as carbon fiber composites are highlighted for their strength-to-weight ratio, with T700 grade carbon fiber being used in less critical components and T1100 grade for primary load-bearing structures [9][11]. Group 3: Carbon Fiber Composites - Carbon fiber composites (CFRP) are essential in commercial aerospace, accounting for 15%-20% of the manufacturing cost of medium-sized reusable rockets, with values exceeding 20 million RMB per unit. In satellite manufacturing, CFRP costs represent 12%-15% of total manufacturing costs for low Earth orbit satellites [10][11]. - The domestic market for carbon fiber is dominated by companies like Zhongjian Technology and Guangwei Composites, with a significant market share in high-strength carbon fiber applications [12][13]. Group 4: Stainless Steel as a Core Material - Stainless steel is recognized for its low cost, high temperature resistance, and strength, making it a key material for reusable rocket technology. It is used in major structural components like rocket bodies and fuel tanks, aligning with the commercial aerospace principle of "reliability equals cost" [15][16]. - The main grades of stainless steel used can withstand temperatures up to 1400°C and maintain structural stability across a wide temperature range, significantly reducing manufacturing costs compared to advanced materials like titanium alloys [15][16]. Group 5: High-Temperature Materials and Refractory Metals - High-temperature materials are critical for rocket engine technology, directly influencing thrust, efficiency, and reusability. Materials such as ceramic matrix composites and nickel-based superalloys are essential for components exposed to extreme temperatures [19][20][25]. - The domestic production of high-temperature alloys, such as GH4169, has reached over 95% localization, indicating a strong domestic supply chain for aerospace applications [26].
