Industry Overview - The carbon fiber industry is characterized by a concentration of production capacity among a few key players, with significant contributions from companies like Jilin Carbon Valley, Zhongfu Shenying, and Guangwei Composite [43][46]. - The global carbon fiber market is experiencing a trend of capacity expansion, driven by increasing demand in sectors like wind energy and military equipment [46][49]. Carbon Fiber Characteristics - Carbon fiber exhibits exceptional mechanical properties, including tensile strength exceeding 3500 MPa, which is 7-9 times stronger than steel, and a density that is one-fourth that of steel [8][10]. - The material is resistant to high temperatures (up to 2000°C in non-oxidizing atmospheres) and low temperatures (-180°C), making it suitable for a wide range of applications [8][10]. Production Process - The production of carbon fiber involves several stages, including the synthesis of polyacrylonitrile (PAN) fibers, oxidation, carbonization, and surface treatment to create carbon fiber products [17][23]. - Different production methods, such as wet spinning and dry-jet wet spinning, are employed to optimize the quality and characteristics of the final product [30][24]. Market Dynamics - The domestic carbon fiber market is expected to see significant growth, with projections indicating an increase in production capacity to 15.3 million tons per year by the end of 2023, and potentially reaching 26 million tons by 2025 [46][48]. - The supply of acrylonitrile, a key raw material for carbon fiber production, is also on the rise, with domestic production capacity expected to improve significantly [38][31]. Competitive Landscape - Major manufacturers in the carbon fiber sector are expanding their production capabilities, with significant investments planned for new facilities and technology upgrades [46][44]. - The competitive landscape is marked by a few dominant players, with Jilin Chemical Fiber leading in production capacity, followed by Zhongfu Shenying and Guangwei Composite [45][39].
