On September 7, 2026, Taiyuan Iron and Steel Co., Ltd.’s Steel Science Department successfully developed a new generation of M40X-grade high-strength, high-modulus, and high-toughness carbon fiber products (brand name TG40MX-6K). This product features a tensile strength of 6.0 GPa and an elastic modulus of 370 GPa, with a fracture elongation rate consistently exceeding 1.5%. It achieves a balanced combination of strength, modulus, and toughness, overcoming long-standing world-class technical challenges. Relying on three established production lines and its own independent research and development technology system, Taiyuan Iron and Steel Co., Ltd. has addressed the inherent defects of high-modulus fibers, such as their high brittleness and low strength, through the control of the precursor structure and optimization of key processes. Currently, this new product has completed trial production and passed full-performance tests, and small batches have been sent to key downstream customers for verification. In the next step, the company will steadily advance process stabilization and industrialization adaptation, continuously addressing the shortcomings in the domestic high-end carbon fiber industry chain.

The tensile strength reaches 6.0 GPa, and the elastic modulus is 370 GPa. After testing by third-party authoritative institutions, the elongation at break is consistently greater than 1.5%, achieving a balanced combination of strength, modulus, and toughness, and overcoming a long-standing world-class technical challenge.
