Investment Rating - The report does not explicitly state an investment rating for the industry or specific companies [1]. Core Insights - Carbon fiber, referred to as "black gold," is categorized into T series (focused on tensile strength) and M series (focused on tensile modulus), with M series being more suitable for space environments due to its high carbon content and modulus [5][19]. - Carbon fiber is utilized in rockets for critical components such as fairings and landing legs, achieving weight reductions of 20%-50%. The Falcon 9 rocket by SpaceX employs carbon fiber in its structures, while the domestic "Weiguang-1" rocket is expected to achieve over 30% weight reduction with full carbon fiber construction by 2028 [5][34][37]. - In satellites, carbon fiber accounts for approximately 15.1% of materials used, primarily in heat sinks and precision structures. Although aluminum alloys dominate at 36.7%, the penetration of carbon fiber is expected to increase due to its low thermal expansion and weight reduction benefits [5][46]. - The M series carbon fiber has high technical barriers, with key bottlenecks in carbonization and graphitization equipment. Companies like Guangwei Composites have a competitive edge in technology and capacity, while others like Zhongfu Shenying and Heshun Technology are also making strides in the M series carbon fiber sector [5][61]. Summary by Sections 1. Carbon Fiber: "Black Gold" Performance - Carbon fiber can be classified based on precursor type, fiber morphology, bundle specifications, production processes, and mechanical properties. The main categories include PAN-based, pitch-based, and viscose-based fibers [13][15]. - Military applications primarily use small bundles of high-modulus carbon fiber, which are essential in aerospace [15][24]. 2. Rocket Applications of Carbon Fiber - Future applications of carbon fiber in rockets are expected to expand to fairings, interstage sections, and landing legs [7][28]. - The D4 rocket uses carbon fiber composites in various critical components, showcasing the material's advantages over traditional metals [33]. 3. Satellite Applications of Carbon Fiber - The increase in satellite weight is expected to drive higher penetration rates of carbon fiber in satellite structures [41][56]. - Carbon fiber is used in satellite components such as heat sinks, precision structures, solar panel supports, and antenna reflectors, benefiting from its excellent thermal and mechanical properties [45][46]. 4. Related Companies - Guangwei Composites leads in M series carbon fiber production with significant capacity and technological advantages, while Zhongfu Shenying and Heshun Technology are also advancing in this field [61][63].

Core Insights - The core viewpoint of the article is that the carbon fiber industry in China has established its own classification methods and technical standards, which align with international practices, particularly the classification system used by Toray Industries in Japan [1].
