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]. Industry Overview - Carbon fiber products can be categorized based on performance indicators, with tensile strength and elastic modulus being the core classification standards widely adopted in the industry [1]. - In 2011, China officially issued the national standard for polyacrylonitrile (PAN) based carbon fiber (GB/T26752-2011), marking the establishment of independent classification methods and technical specifications for the domestic carbon fiber industry [1]. Product Categories - The T series and M series are significant product categories within carbon fiber, both classified according to key performance parameters such as tensile strength and elastic modulus [1]. - The M series carbon fiber is categorized as a high-strength and high-modulus product, which has a more complex manufacturing process and higher added value compared to the T series [1].
