A technical appraisal meeting presided over by the China Petroleum and Chemical Industry Federation was held on August 20, and China-made ultra-high-strength ZA60XC (T1000) PAN carbon fiber 1000 ton-class industrial production technology passed the technical appraisal of the expert committee. The expert committee stated, “This achievement has reached the world’s top level. Among them, the precursor structure design and representation analysis technology lead the world, and the appraisal was unanimously passed.
Carbon fiber is known as the “gold of industry” and the “king of new materials.” With its high strength, high Young’s modulus ratio, corrosion resistance, fatigue resistance, and high temperature resistance, carbon fiber is an indispensable strategic material in such fields as aerospace, national defense and military industry, transportation, new energy, and marine engineering. For a long time, the most core advanced technology of carbon fiber, especially the technology for large-scale mass production of ultra-high-strength carbon fiber, has been monopolized by developed countries.
According to Changsheng Technology officials, the demand for carbon fiber and its composite materials is rapidly increasing with China’s economic and social development. China’s carbon fiber production has gone from near zero to accounting for one-third of global production by 2022. Most production capacity, however, remained at the T300 and T700 levels. High-end T800 products lacked quality stability, and ultra-high-performance carbon fiber products above T1000 had only 100-ton-level technological achievements, and large-scale and stable production at the 1000-ton level could not be realized. After more than two years of research and development, in which Changsheng Technology was in charge and Shenzhen University cooperated, a production line with an annual capacity of 1,700 tons was able to stably produce T1000 products. According to inspections, its performance has reached the level of comparable products in the world, with a product quality acceptance rate of more than 95.6%.
