The preparation of carbon fiber is a systematic project, which includes a series of complex physical and chemical reactions. The mechanism of some reactions has not been thoroughly studied. The equipment required for some reactions is difficult to meet higher requirements, and the preparation is very difficult. The technology is blocked by foreign countries, so to a certain extent, the preparation of carbon fiber in my country depends on itself. The basic localization of T300 and T800 (two carbon fiber models) realized now is the result of the unremitting efforts of several generations of scientists and engineers. . The domestic carbon fiber industry is not mature. There are carbon fiber companies with carbon fiber production technology and a certain scale. Their customers are countries and military projects, and military projects are exaggerated to say that they do not count the cost. Therefore, the current carbon fiber cost is relatively high, because the enterprise produces In order to meet the needs of the country, there is no incentive and no need to consider reducing production costs.

In terms of civilian use, carbon fiber products such as carbon fiber bicycles and tennis rackets have less stringent requirements than military industry because of their raw material properties, so they mainly rely on imports. However, the international carbon fiber market is not fully competitive, and most of the shares are sold by Japan and Japan. A few companies in the United States and other countries are monopolized, which leads to the high price of carbon fiber products. Some people say that the quality of domestic carbon fiber is not high, and it is not as good as imported carbon fiber. This is because the development of domestic carbon fiber is not well known, causing this feeling of being taken for granted. In fact, different types of carbon fibers have their own standard indicators. In the process of completing the localization of military carbon fibers, Chinese scientists and engineers are constantly making the performance of the carbon fibers prepared by themselves approach or exceed the standard indicators and achieve stable production. . Therefore, the quality of carbon fiber has nothing to do with domestic or imported, only with the model.
