Changsheng Technology releases high-performance ZA40MX carbon fiber with an annual production capacity of 350 tons

Thread Content

Recently, Changsheng Technology officially launched the new generation of high-performance carbon fiber product ZA40MX, with a stable production capacity of 350 tons per year. This marks not only a milestone in technological advancement for domestic carbon fibers at the M40X level, but also demonstrates a solid capability for mass production and market supply. In 2026, higher-performance carbon fibers covering the M40 to M55 ranges will be introduced one after another, further enhancing the portfolio of high-end products and establishing a material value system centered on performance. As another significant achievement following the development of domestically produced large aircraft, this product’s core performance is on par with that of similar products manufactured by Japan’s Toray. It is capable of steady mass production thanks to China’s first self-designed 2-meter-wide high-temperature graphitization production line, thereby achieving a systematic breakthrough in terms of process autonomy, product consistency, and the ability for large-scale supply of high-end domestic carbon fibers. With a comprehensive upgrade in performance, its key indicators have reached international advanced levels. The ZA40MX matches the core mechanical properties of Japanese Toray products: its tensile strength is ≥5490 MPa, tensile modulus is ≥377 GPa, elongation at break is ≥1.45%, and linear density is 515 g/km. While maintaining ultra-high strength, the product boasts excellent structural stiffness and fatigue resistance, enabling it to withstand the severe mechanical challenges in fields such as aerospace and high-end equipment, and providing reliable and stable material support for critical applications. Thousand-ton production line + ultra-high-temperature graphitization technological upgrades: Engineering breakthroughs drive industrial upgrading. The large-scale implementation of ZA40MX has seen its production platform go through three stages – independent design and construction, large-scale stable operation, and advanced technological upgrades – resulting in a flexible production system featuring \"one production line for multiple product grades\", which is rare in China. The originally developed 1,000-ton production line has enabled the stable mass production of high-end T-series products. Through technological upgrades to key processes, the bottleneck in the production of high-modulus carbon fiber was successfully overcome, facilitating a technological leap from the T-series to the M-series. It integrates a 2-meter ultra-wide and ultra-high-temperature graphitization furnace developed independently. As the core equipment with the highest production capacity per line and the greatest degree of process integration among similar production lines in China, it leverages its technical advantages of wide width, high temperature, and continuous operation to ensure the uniformity and reliability of product performance. After the technical upgrades, the production line retains its original capacity while also possessing the ability to switch products flexibly. The annual production volume of ZA40MX is expected to reach 350 tons, providing a stable and reliable supply of materials for industries such as aerospace and high-end manufacturing. This production line not only enables the mass production of M40X-grade products domestically, but also establishes a sustainable development model based on \"large-scale production lines combined with high-end product development,\" providing a replicable engineering model for the upgrading of China’s carbon fiber industry toward higher-value areas. From aerospace to high-end civilian applications: multi-functional use across a wide range of performance requirements. From heavy aerospace equipment to high-end civilian devices, ZA40MX meets the needs of various applications with its excellent performance, truly demonstrating the technical versatility of \"one material, endless possibilities\". Aerospace sector: Used in key structural components such as satellite mounts and rocket casings, it significantly reduces the weight of systems, enhances the payload capacity, and contributes to the efficient progress of aerospace projects. High-end industry: Meets the requirements of equipment such as drone frames and precision robotic arms, ensuring the accuracy and stability of operation through its high stiffness. Sports and leisure: It enhances products such as competitive fishing rods, ultra-light bicycle frames, high-performance rackets, and ski poles; by upgrading the materials, it achieves three improvements in terms of equipment sensitivity, control precision, and durability, meeting the high-demand needs of enthusiasts of extreme sports.
