Why are carbon fiber composites so expensive?

Carbon fiber composite material is an advanced composite material with superior performance. It is characterized by light weight, high strength and good fatigue resistance. In addition, due to its high temperature, corrosion resistance and easy processing, it is widely used in aerospace, automobile, medical, uav and other fields. Because carbon fiber production process is very complex, and the price is relatively high, all in their daily life does not see more, especially high performance carbon fiber as a result of the foreign technical barriers and materials limited, at present only in the field of military industry, aerospace and other cutting-edge technology in a wide range of use. Carbon fiber is found in new fighters, rockets, precision-guided weapons, and military pods.


Why are carbon fiber composites so expensive?

Carbon fiber material is a kind of high-performance emerging materials, due to its light Gao Jiangnai corrosion excellent material properties, such as many areas all want to carbon fiber composite material to replace the traditional materials to enhance the overall performance of the product. However, many customers who have contacted carbon fiber products have found that the cost of using carbon fiber is much higher than that of traditional materials. It often does not understand why carbon fiber composite materials are so expensive. The following shandong yingtuli new material is to explain to everybody.

Carbon fiber is expensive

The core production technology of carbon fiber is monopolized in developed countries such as Japan and the United States, and it has been a close technical blockade of China because of its involvement in the defense industry. In the past basic unable to domestic carbon fiber, through the national policy support and efforts to develop domestic enterprises, the current domestic carbon fiber can already under batch production T800 carbon filament, but relatively nissan is a bit poor product quality. T800 products can only be produced in small quantities at home, the T800 and the M series can't be produced in quantity, and the raw silk materials are monopolized or banned by foreign countries, so the price is relatively high. In addition, the materials that produce carbon fiber are more expensive, and the process is very complicated, so the carbon fiber raw silk is not cheap. At present, low-end carbon fiber is cheaper than before because of the domestic mass production and low price industries abroad, but high-end carbon fiber material is still a high price for luxury goods.

Carbon fiber composite materials are expensive to make

Carbon fiber raw silk wants to be used must make compound material to be able to process the product that wants to be specific, carbon fiber silk needs to be prepared to make cloth, still need to combine with resins to make preleaching material. The production process of carbon fiber products requires high temperature curing, vacuum importing, hot pressure tank and so on. The production process is very complicated, demanding high precision and high requirements for technicians. In terms of the carbon fiber product development design, carbon fiber layer, such as strength test needs a large number of experiments, such as salt fog and corrosion resistant, through testing, such as wave rate at the same time need to develop a high precision mould, this directly promoted product overall cost. Some of the carbon fiber products require high temperature, high strength, and the selection of resin and fiber models will increase the price of carbon fiber products.

At present, the carbon fiber market belongs to the emerging industry, and many products belong to the pre-research stage, and the standardized products are less. As a result, the overall r&d, design, experiment and other costs are included in the product cost, so the price of carbon fiber products is on the high side. For products that reach a certain number of orders, it is cost-effective. Friends with the need of carbon fiber products can dock with the new technology to make the domestic carbon fiber industry faster and more mature.


Why are carbon fiber composites so expensive?

Carbon fiber composites, however, the price is expensive, but still has a lot of outstanding advantages, Internet force new material company production of carbon fiber composite materials products application in various fields, to improve product performance, such as cars, can reduce the vehicle weight, reducing energy consumption, increase the intensity of the vehicle. In the medical field, application in the medical CT bed board, X rays, through the performance is better than that of any other material, is the best material used and can not be replaced, application fields of aeronautics and astronautics, has incomparable advantages.
