T800 grade carbon fiber has broad application prospects in the aerospace field. Local companies have 1,000-ton production capacity.

Based on different tensile strengths, carbon fiber can be divided into T700 carbon fiber, T800 carbon fiber, T1000 carbon fiber, etc. T800 grade carbon fiber is a high-performance carbon fiber, which refers to carbon fiber with a tensile strength of 5880Mpa. T800 grade carbon fiber has the advantages of corrosion resistance, high tensile strength, good mechanical properties, high temperature resistance, and wear resistance. It has broad application prospects in hydrogen storage bottles, aerospace and other fields.

Spinning is a key link in the production of T800 carbon fiber, including dry-jet wet spinning and wet spinning. Dry-jet wet spinning method, also known as dry-wet spinning method, refers to preparing the spinning solution first, then pressing it out from the spinneret, passing through the air section, and then through solidification, forming, stretching and other processes to obtain the finished product; wet spinning refers to Directly solidify the thin stream of spinning liquid squeezed out from the spinneret, and then undergo post-processing to obtain the finished product. The dry-jet wet spinning method has the advantages of fast spinning speed and good quality of finished products, and is a commonly used spinning process for T800 carbon fiber.

According to the “2023-2028 China T800 Grade Carbon Fiber Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, T800 grade carbon fiber has broad application prospects in hydrogen storage bottles, aerospace and other fields. In the field of hydrogen storage cylinders, T800 grade carbon fiber can be used to manufacture type III hydrogen storage cylinders and type IV hydrogen storage cylinders, and hydrogen fuel cell vehicles are their end products; in the aerospace field, T800 grade carbon fiber has the advantages of good toughness and high strength, and can Used as raw material for stressed parts. In May 2023, my country’s domestically produced large passenger aircraft C919 completed its first commercial flight. Its sandwich structure used T800 grade carbon fiber composite materials.

The world’s leading T800 carbon fiber company is Japan’s Toray Co., Ltd. (TORAY). Its main products include T800H carbon fiber and T800S carbon fiber. It is one of the first companies in the world to deploy high-strength medium-module carbon fiber. In terms of the local market, compared with Japan, my country’s T800 carbon fiber industry started late, and product quality and performance are relatively poor. In recent years, attracted by market prospects, the number of companies in my country that have deployed T800 grade carbon fiber R&D and production has been growing, including Zhongfu Shenying, Zhongjian Technology, Guangwei Composite Materials, AVIC Hi-Tech, etc.

Zhongjian Technology is a representative company of T800 carbon fiber in my country. It focuses on the research and development, production and sales of high-quality carbon fiber for aerospace. Its main products include ZT7, ZT8, ZT9 and other series of carbon fibers. It has thousands of tons of T800 carbon fiber production technology. . At present, the T800 grade carbon fiber produced by Zhongjian Technology is mainly used in the military field.

Industry analysts said that T800 grade carbon fiber, as a high-performance carbon fiber, has broad application prospects in many high-tech fields. my country’s T800 carbon fiber industry started late, but it is developing rapidly, and local companies already have 1,000-ton production capabilities. It is expected that in the future, with in-depth research and technological advancement, the quality and output of my country’s T800 carbon fiber will further improve.
