On June 20th, the National High-Level Ceramic Fiber National and Local Joint Engineering Research Center officially settled in Suzhou Industrial Park. The center will focus on the engineering of organic precursor-converted ceramic materials and promote the development of the national high-performance ceramic fiber industry. The high-performance ceramic fiber industrialization seminar was held at the same time. Six academicians of the Chinese Academy of Engineering and more than 50 relevant industry experts gathered to discuss the development direction and industrialization of high-performance ceramic fiber.

Ceramic fiber has the advantages of light weight, high temperature resistance, small heat capacity and good heat insulation performance. It can be widely used in metallurgy, electric power, machinery and chemical heat energy equipment to achieve the effect of heat preservation. Compared with traditional materials, it is more energy efficient and has a broad development prospect. “High-performance Ceramic Fiber National and Local Joint Engineering Research Center” was built by Suzhou Saifei Group Co., Ltd., Institute of Aerospace Materials and Technology, China Aerospace Science and Technology Corporation, Suzhou Institute of Nanotechnology and Nano-Bionics, Chinese Academy of Sciences, Institute of Chemistry, Chinese Academy of Sciences Beijing University of Aeronautics and Astronautics, Suzhou University, Tianjin University of Technology, etc.

The National High-Level Ceramic Fiber National and Local Joint Engineering Research Center brings together domestic academicians, materials experts and high-end engineering and technical personnel to form a basic research and engineering project focusing on silicon carbide fiber and engaged in multi-variety and serialized high-performance ceramic fibers. Research and development of research and application technology research teams. At present, the center has set up four laboratories and an analytical testing center with over 20 research projects.

In the future, the Engineering Research Center will take the demand for functional silicon carbide fiber composite materials in the national major engineering and civil high-tech fields as the traction, and focus on solving the bottleneck problems of key technologies and equipment in industrial development, and promote industrial technology advancement and structural adjustment. Leading and driving the development and application of functional silicon carbide fiber and its composite materials in China, supporting and promoting the leap-forward development of China's aviation, aerospace and marine equipment, and becoming the source of innovative technology and research and development core in China's high-performance ceramic fiber field. Industrial Technology Center, Talent Training Center, Technical Consulting Service Center and International Exchange and Cooperation Center.
