1. The raw materials for carbon fiber mainly come from polymer organic compounds and petroleum extracts. In the production process, only 1 ton of carbon fiber can be burned from 2-2.2 tons of raw silk, with a cost of about 40000 to 60000 tons, which is 4-5 times that of steel.
2. High electricity costs: The processing technology of carbon fiber mainly involves heat treatment, which requires a large amount of electricity. Electricity accounts for 25% -30% of the production cost of carbon fiber, making it a major electricity consumer.
3. The process is complex and costly: the research and production of carbon fiber involves interdisciplinary research, and the entire process is long and complex, involving various chemical catalytic reactions. As a high-tech product, its research and production costs are extremely high, and many companies have strict protection measures for their processes and formulas, making the entry threshold quite high.
4. Carbon fiber has excellent properties such as light weight, high strength, high modulus, excellent high temperature resistance, and corrosion resistance. These characteristics make carbon fiber widely used in high-end fields such as aviation, aerospace, automotive, and sports equipment, further supporting its high price.
