The inherent advantages of carbon fiber precursor filaments establish them as a core foundational material across strategic sectors such as aerospace, new energy, high-end equipment manufacturing, and the "low-altitude economy." Furthermore, China's recent breakthroughs in T1200-grade precursor filaments and large-tow technologies are accelerating the realization of independent control and large-scale application for domestically produced high-end carbon fibers.
High Strength and High Modulus
Tensile strength can reach 5 to 10 times that of steel; for instance, the engineering-grade tensile strength of T1200-class carbon fiber reaches 7,566 MPa, with laboratory peak values reaching 8,056 MPa.
High modulus: specifically, pitch-based precursor filaments can achieve an ultra-high modulus after graphitization, making them suitable for aerospace structural components with extremely stringent stiffness requirements.
High-Temperature Resistance and Thermal Stability
Capable of withstanding temperatures exceeding 2000°C in an inert atmosphere without melting or softening.
It possesses an extremely low coefficient of thermal expansion-which can even be negative (e.g., in pitch-based carbon fibers)-making it suitable for use in extreme thermal environments.
Lightweight and Low Density
Carbon fiber has a density of 1.5–2.0 g/cm³-merely one-quarter that of steel and half that of aluminum alloy-significantly reducing the weight of end products and enhancing energy efficiency.
Corrosion Resistance and Chemical Stability
Exhibits excellent resistance to environments involving acids, alkalis, salt spray, and similar agents; shows no significant changes even after immersion in aqua regia.
Suitable for use in corrosive environments within the marine, chemical, and aerospace industries.
