Why is carbon fiber be so expensive?

Carbon fiber materials are used more and more, the strength is harder than steel, but the weight is much lighter. It is widely used in high-end fields, spacecraft, cars, medical devices, bridges and tunnels and so on. In terms of composition, carbon fiber is a material with a carbon content of more than 95%. This material is made of organic fibers such as flake graphite microcrystals stacked along the fiber axis, and then carbonized and graphitized.

So why is the price of carbon fiber so expensive?

1. The production cost is high.

The production of carbon fiber is a very complex process, from the preparation of the precursor to the finished product, each step of the production process has high requirements, the need for high-precision control, the requirements of equipment is very high. The high cost of initial equipment investment and maintenance is one of the reasons for the high price of carbon fiber.

2. The energy consumption is high

The production of carbon fiber is still a high energy-consuming process. In particular, the late carbonization graphitization requires a very high temperature, and the high energy consumption in the production process is another reason for the high cost of carbon fiber.

3. Raw materials are expensive

Carbon fiber is “woven” and requires high strength, densification and high purity raw materials. The production cost of raw materials is high.

4. High technical requirements and imbalance between supply and demand.
