Continuous silicon carbide fibers (SiC fibers) and the ceramic matrix composites (CMCs) reinforced with them have demonstrated exceptionally broad application prospects in extreme‑environment fields such as aerospace and the nuclear industry, thanks to their outstanding high‑temperature resistance, oxidation resistance, and mechanical properties.
On May 28, 2025, the mid-term progress meeting for the China Association for Science and Technology’s 2024 National Society Project—“Research Report on High-Performance Inorganic Fibers and Products for Aerospace Applications,” undertaken by the Chinese Society of Textile Engineering—was successfully held at Wuhan Textile University.
On July 4, 2026, the “Fourth National Defense Science and Technology Summit Forum—Sub‑Forum on High‑Performance Inorganic Fibers and Their Application Technologies” and the Second National Academic Exchange Conference on High‑Performance Inorganic Fibers and Products were successfully held in Changsha, Hunan Province. The event was co‑hosted by the China Textile Engineering Society, the School of Aerospace Science of National University of Defense Technology, and the National Key Laboratory of New Textile Materials and Advanced Processing, with the Professional Committee on High‑Performance Inorganic Fibers and Products of the China Textile Engineering Society serving as the organizer. The conference was chaired by Liu Haitao, Director of the National Key Laboratory of Novel Ceramic Fibers and Their Composites at National University of Defense Technology, and brought together more than 140 participants, including experts and enterprise representatives from across the country in the field of inorganic fibers.
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.
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.
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.
