The world's carbon fiber production has reached more than 40,000 tons per year. The world's major countries, Japan, the United States, Germany, and South Korea, have mastered the core technologies of carbon fiber production and have large-scale production.
At present, the global carbon fiber core technology is firmly in the hands of a few developed countries. On the one hand, developed countries led by the United States and Japan have always maintained a strict technical blockade on China's carbon fiber industry; on the other hand, foreign carbon fiber industry leaders have begun to enter the Chinese market, and the pressure on China's domestic carbon fiber companies has increased. Although China has increased its guidance and support for the carbon fiber industry, under the larger technological gap, the breakthrough path of domestic carbon fiber is still bumpy.
