Carbon fiber technology ushered in a new breakthrough in high-speed spinning results won the academician affirmed

On March 29th, the “High-strength carbon fiber high-efficiency preparation industrialization technology project” jointly undertaken by Weihai Expanded Fiber Co., Ltd. and Beijing University of Chemical Technology successfully passed the acceptance test. The expert group unanimously agreed that the result has completely independent intellectual property rights and produces GQ4522 grade (TZ700S, CCF700S) carbon fiber through dry-jet wet spinning process, achieving stable operation of the spinning speed of 500 m/min raw silk. After carbonization of products Performance indicators and their stability are comparable to international T700S grade carbon fiber.

The appraisal meeting was organized by the China National Textile and Apparel Council. Sun Jinliang, academician of the Chinese Academy of Engineering, and Yu Jianyong, academician of the Chinese Academy of Engineering, and other expert committees of seven experts inspected the production site, listened to the report on the company's project results, and highly praised the research results.

The project is a project of China Textile Industry Federation and Shandong Carbon Fiber Technology Innovation Center. It is a key technology of Weihai Development and Beijing University of Chemical Technology, which is based on the National 863 Program “Development of CCF-3 Carbon Fiber Industrialization Technology by Wet Spinning”. Project research on the spinning speed and stability of existing domestic T700S carbon fiber.

Experts have identified that the successful development of the 500 m / min spinning speed production of high-performance carbon fiber spinning technology is the first breakthrough in the country, the overall technology has reached the international advanced level, the appraisal committee unanimously approved the identification. Weihai's expansion of carbon fiber products has also been applied to a certain type of solid rocket engine housing, as well as aviation, weapons and other fields.

The acceptance is of great significance. Weihai's breakthrough of 500 m/min spinning key technology has promoted the improvement of domestic carbon fiber dry-wet spinning technology, which is conducive to further reducing the production cost of dry-wet carbon fiber, which is beneficial to domestic production. The further promotion and application of carbon fiber will have a leading role in the industry.

The demonstration application of this project in the field of military-civilian integration not only supports the development needs of key weapon models, but also continuously meets the application requirements of high-end industrial equipment fields, and provides favorable conditions for Weihai to further develop the market and positively develops the company's future business performance. influences.
