Carbon fiber square tube has a series of advantages such as light weight, high strength, high temperature resistance, corrosion resistance and aging resistance, so many people tend to use carbon fiber products, and there are some high-tech products, but the price of carbon fiber square tube products is generally high. What is the reason for this?
The main reason for the high price of carbon fiber products is its raw material-carbon fiber. All carbon fiber products are processed from carbon fiber precursors. The carbon fiber precursors are obtained by pre-oxidizing, carbonizing, and graphitizing different matrix carbon fibers in a high temperature environment. It needs to be drawn and dried for many times to densify. The energy is very much, and the production cost is also increasing. Furthermore, the technology required for the production of carbon fiber products is very high. The production of carbon fiber is an extremely complex process, which involves a series of physical and chemical reactions, and the pursuit of higher strength and higher modulus is now This research and development needs to invest a lot of money, like some products with high performance requirements, it needs to use high-quality carbon fiber, so the price is relatively higher. The last one is the monopoly of technology. We all know that the core technology of carbon fiber is in the hands of a few developed countries such as Japan and the United States. However, the strength of domestically produced carbon fiber generally does not meet the requirements, so basically the carbon fiber used depends on imports. It is up to the supplier, and they also prohibit the leakage of technology, so the domestic carbon fiber industry is developing slowly.
