Recently, a 1MW carbon fiber microwave graphitization production line jointly developed by Jinggong Technology and Yonghong Advanced Materials Co., Ltd. has made a major breakthrough. According to the results of large-volume full-load test, the conventional T300/T400 carbon wire passes through the production line microwave. After graphitization, the modulus and strength can be increased by 10%-15%, and the final product quality grade is above T700/T800. All technical indicators have reached the design requirements. The main technology of the whole line has filled the domestic gap and has successfully completed this. Various R&D trial production work of the production line.
