R&D Innovation

ChangSheng Caebon possesses advanced production technologies, leading-edge equipment, top-tier talent, and extensive industrial production experience across three key process stages: polymerization, spinning, and carbonization.

On August 20, 2023, the company successfully passed the scientific and technological achievement appraisal for its "Industrial Production Technology for Thousand-Ton Scale Production of Ultra-High Strength ZA60XC (T1000-grade) PAN-based Carbon Fiber," organized by the China Petroleum and Chemical Industry Federation. The appraisal confirmed that the technology's proficiency is domestically leading and internationally advanced.

Building on this success in high-end carbon fiber development, ChangSheng continued its R&D efforts towards aerospace-grade T1100 carbon fiber, based on its T1000-grade foundation. On September 29, 2024, the company completed the appraisal for its "Industrial-Scale Preparation Technology for Ultra-High Strength PAN-based Carbon Fiber ZA70GC (T1100-grade)," organized by the China Society for Composite Materials. Experts recognized the project as highly complex and challenging, concluding that the resulting technology is mature, reliable, independently controllable, supported by multiple proprietary intellectual properties, and overall domestically leading and internationally advanced.

Leveraging its existing advanced technology while continuously pursuing breakthroughs, ChangSheng's 800 tons/year high-performance carbon fiber carbonization line project utilized independent process design and was manufactured domestically. The project was remarkable for being designed, constructed, completed, and commissioned successfully on its first attempt within the same year, achieving key equipment localization for the carbonization process.

R&D Platforms: ChangSheng currently operates two provincial-level R&D platforms: the Hebei Province Carbon Fiber Industry Technology Research Institute and the Hebei Province Carbon Fiber Technology Innovation Center. These platforms solidify the foundation for the company's technological innovation within the carbon fiber industry.

Provincial Science & Technology Projects:

* As a partner, participated in the provincial key R&D project "70MPa Capacity Hydrogen Storage Cylinder Key Technology and Application Demonstration," responsible for developing the carbon fiber for the cylinders. This project has been concluded.

* As the lead applicant, applied for the provincial Central Government Guides Local Science and Technology Development Fund project "ZA55TC-24K High-Performance Carbon Fiber Key Preparation Technology Integration and Demonstration."

* As a partner, is participating in the Shenzhen Major Special Project "Key Technology R&D for Stable Engineering-Scale Production and Application of T1000-grade Carbon Fiber," responsible for the mass production of T1000-grade carbon fiber. This project is progressing in an orderly manner.

ChangSheng emphasizes intellectual property protection, currently holding 64 authorized patents, including 37 invention patents and 27 utility model patents.

Fostering innovation, ChangSheng actively engages in industry-academia-research collaboration. It cooperates with institutions like Hebei University of Technology, Shenyang Aerospace University, and Shenzhen University in areas such as basic research on high-performance carbon fiber, development of resins for carbon fiber composites, and interface performance assessment of composites, effectively bridging theory and practice to accelerate technological innovation.

ChangSheng is independently developing sizing agents for carbon fiber production. The design for a 100 tons/year sizing agent production line is complete, with construction and commissioning scheduled for the first quarter of 2025. This initiative aims to achieve self-sufficiency and import substitution for sizing agents.

In an industry-first innovation, ChangSheng has developed a novel technique for preparing prepreg using uniaxial carbon fiber tows for laminate fabrication. A patent application for this invention has been filed. Tests confirm that this technology not only reduces the number of creels and carbon fiber waste during prepreg preparation but also decreases the equipment footprint and energy consumption, enabling faster and more efficient prepreg sampling and production.
