Why is carbon fiber so expensive?

There are three main reasons why carbon fiber is expensive:

1. Expensive raw materials: Modern carbon fiber raw materials mainly come from polymer organic compounds and petroleum extracts. Generally speaking, 2-2.2 tons of precursor only need to burn 1 ton of carbon fiber, and the cost is about 40,000-60,000 tons, which is 4-5 times that of steel.

Second, the electricity fee is expensive: the processing technology of carbon fiber is mainly heat treatment, which requires a lot of electricity. The electricity bill accounts for 25%-30% of the production cost of carbon fiber, and it is a veritable big electricity user.

Three. Expensive technology: Because it is a multidisciplinary product, the research and development cost of carbon fiber is extremely high, and various chemical catalytic reactions will be involved in the production process. The whole process is long and complicated. As high-tech products, many companies have strict protection measures for their own processes and formulas, which can be said that the entry threshold is quite high.

Carbon fiber is an inorganic polymer fiber with carbon content higher than 90%, and it is a microcrystalline graphite material obtained by graphitizing organic fiber. Generally speaking, it is a fibrous compound or polymer that has been specially treated. It has the inherent characteristics of hard carbon materials and the soft processing characteristics of textile fibers, and is called the king of materials.

The initial form of this polymer is a bundle of slender materials with a diameter of only 0.005-0.01mm. In order to produce carbon fiber, thousands of bundles of materials need to be tied together to form yarn-like fiber bundles, which can be used alone or woven into fabrics.

Or yarns and fabrics are combined with epoxy resin, wound or molded to form various composite materials. Carbon fiber reinforced composites are usually used to manufacture aircraft and spacecraft parts, racing car bodies, golf club shafts, bicycle frames, fishing rods, car springs, sailing masts and many other parts that require light weight and high strength. The carbon fiber component you usually see is this kind of processed carbon fiber composite component. Million car purchase subsidy
