Industry Advantages

Silicon carbide fiber-reinforced composites can be classified according to the ceramic matrix and the type of reinforcing fibers. Among them, continuous silicon carbide fiber-reinforced silicon carbide ceramic matrix composites (SiC/SiC) are currently recognized internationally as one of the most promising materials for high-temperature engine structural applications.

Technological Advantages

In 1975, the Yajima group at Tohoku University in Japan synthesized continuous SiC fibers with diameters of approximately 10 μm, using polycarbosilane as the precursor. Shortly after Japan’s successful development of SiC fibers, China recognized the material’s potential applications and initiated efforts to establish a technological R&D framework for silicon carbide fibers, embarking on a journey of independent innovation.

Breaking through core technologies! Zhongxing New Materials has achieved the engineering-scale production of third-generation continuous SiC fibers.

The company has successfully scaled up the production of first-, second-, and third-generation continuous silicon carbide fibers by leveraging its proprietary electron-beam‑assisted active‑atmosphere crosslinking technology, with the resulting products achieving performance levels on par with international best practices. With all key technologies and equipment fully under domestic control, this milestone marks a critical step forward for China in the field of high‑performance continuous ceramic fibers.

Through deep integration of industry, academia, and research, Zhongxing New Materials has established two core technological systems.

Ningbo Zhongxing New Materials adheres to collaborative innovation among industry, academia, and research, maintaining close partnerships with China’s leading scientific institutions. The company has established robust technological platforms for the preparation of high-performance ceramic fibers and the synthesis of specialty ceramic precursors, thereby forming a complete innovation chain that spans fundamental research, laboratory-scale trials, pilot-scale production, and full-scale industrialization, continuously strengthening its core competitiveness.

Zhongxing New Materials has become a qualified supplier to multiple aerospace organizations.

Thanks to its stable and reliable product quality and strong technical capabilities, Ningbo Zhongxing New Materials has been designated a qualified supplier by numerous domestic aerospace‑related organizations, providing key materials such as silicon carbide fibers and polycarbosilane in bulk, thereby ensuring the supply of critical “bottleneck” materials for major national projects and the development of high‑end equipment.

An advanced testing platform empowers R&D, enabling Zhongxing New Materials to maintain its leading position in the new materials sector.

The company is equipped with internationally advanced analytical and testing instruments and has established a comprehensive quality-control and R&D‑validation system, providing a robust technological and equipment foundation for the iterative development of next‑generation high‑performance ceramic fibers and specialty ceramic precursors. Looking ahead, Zhongxing New Materials will continue to deepen its expertise in the high‑end ceramic fiber sector, contributing to the nation’s drive to become a global leader in materials science and technology.
