Shanghai, March 2026 - ChangSheng Technology announced today the official launch of its new-generation ZA40MX high-performance carbon fiber, with an annual production capacity of 350 tons. This milestone marks a major breakthrough in China's ability to mass-produce M40X-grade carbon fiber, demonstrating not only technological achievement but also industrial readiness for large-scale supply.

Following its earlier success in supporting China's domestic large aircraft program, ZA40MX meets the core performance standards of Japanese manufacturer Toray's equivalent M40X-grade products. Utilizing China's first independently developed 2-meter ultra-wide high-temperature graphitization line, the fiber achieves consistent quality and stable output - a significant leap forward in process autonomy, product reliability, and scalable manufacturing for domestic advanced carbon fiber.

1. Performance Reaches World-Class Level

ZA40MX delivers mechanical properties matching international benchmarks, with tensile strength ≥ 5,490 MPa, tensile modulus ≥ 377 GPa, elongation at break ≥ 1.45%, and linear density of 515 g/km. The material offers high stiffness, excellent fatigue resistance, and reliability under extreme conditions, making it suitable for demanding aerospace and high-end industrial applications.

2. Homegrown Production Line Enables High-Modulus Fiber Mass Production

ZA40MX is manufactured on a flexible, upgraded thousand-ton production line that enables the transition from T-series to M-series carbon fiber. The core of the process is a self-developed 2-meter ultra-wide high-temperature graphitization furnace - the largest and most integrated of its kind in China - which ensures consistent product quality through wide-width, continuous, high-temperature processing. With annual output of 350 tons, the line provides reliable supply for aerospace and advanced industrial users.

This engineering milestone represents more than a single product success; it establishes a replicable model for scaling domestic high-modulus carbon fiber production, enhancing China's strategic autonomy in advanced materials.

3. Versatile Applications Across Aerospace, Industry & Sports

ZA40MX serves diverse high-performance scenarios:

* Aerospace: Satellite structures, rocket components - reducing weight while improving payload capacity.

* High-End Industrial: Drone frames, robotic arms - delivering stiffness and precision.

* Sports & Leisure: High-grade fishing rods, bicycle frames, rackets, and ski poles - enhancing sensitivity, control, and durability.

4. Roadmap for Higher-Performance Carbon Fiber

ZA40MX is the first step in ChangSheng’s high-modulus product strategy. The company has laid out a clear technology pathway and plans to introduce M40- through M55-grade carbon fibers in 2026, expanding its high-end portfolio and reinforcing China’s position in the global advanced materials landscape.

With ZA40MX, ChangSheng Technology moves domestic carbon fiber from import substitution to performance-driven preference, providing a reliable, high-quality material foundation for China's aerospace, industrial, and consumer innovation sectors.
