Chang Sheng (Langfang) Technology Co., Ltd. (Abbreviation: Changsheng Carbon) was established on December 2, 2021. Headquartered in the Langfang High-tech Industrial Development Zone, Hebei Province, with a registered capital of 1.708 billion RMB, the company is a high-tech enterprise specializing in the R&D, production, and sales of high-performance carbon fiber and composite materials.

The company possesses domestically leading technological capabilities in the high-performance carbon fiber sector. It is the first and only enterprise in China to have achieved industrial-scale production of T700, T800, T1000, and T1100-grade carbon fibers simultaneously. Notably, the first-pass yield for T700 and T800-grade fibers exceeds 98%, and thousand-ton-scale industrial production for T1000 and T1100 grades has been realized, breaking international monopolies. The performance indicators of its various carbon fiber specifications surpass those of comparable industry products.Chang Sheng Technology's independently designed thousand-ton carbonization line features fully localized key core equipment, strongly demonstrating the company's capability for rapid replication of high-performance carbon fiber production lines. Its independently developed thousand-ton industrial production technology for T1000-grade ultra-high strength carbon fiber (ZA60XC) passed the technical appraisal organized by the China Petroleum and Chemical Industry Federation. This achievement signifies a breakthrough in China's high-end carbon fiber technology against long-standing international technical blockades and product controls, marking its entry into a phase of synchronous development with global high-end carbon fiber advancements.Furthermore, the company's independently developed ZA55GC carbon fiber product successfully obtained PCD (Process Certification Document) pre-approval from COMAC and AVIC, indicating that Changsheng Carbon has formally entered the core supply chain for civil aviation aircraft.
