On December 25, 2025, ChangSheng Carbon's independently developed ZA55GC carbon fiber received the 'Engineering Certificate of Qualified Material and Standard Parts' from Commercial Aircraft Corporation of China, Ltd. (COMAC). This confirms that ZA55GC meets the strictest standards for performance, quality, reliability, and airworthiness in civil airliner manufacturing, officially entering COMAC's supply chain.
The approval, China's highest recognition for aviation material suppliers, followed a three-year rigorous evaluation by COMAC experts, covering design, production processes, and quality systems. ZA55GC excelled due to its superior performance and batch stability, making ChangSheng Carbon the only domestic supplier to integrate carbon fiber into load-bearing components of Chinese large aircraft, with simultaneous full-aircraft rollout.
This milestone validates ChangSheng Carbon's technical and management strengths, proving its ability to provide safe, reliable, advanced materials and components for civil aviation.
'Becoming a qualified COMAC supplier is an honor for our team and a profound responsibility,' said Chairman Wang Zhiguo. 'It ushers in a new era of substantive, deeper collaboration.'
