The System Control And Experimental Study Of Kilometer Asphalt Carbon Fiber

Carbon fiber is a new material with excellent properties applied to the aviation and other high-tech field. It is praised as the summit of the materials comprehensive properties all over the world and called the black revolution in the 21st century. Therefore, the research on carbon fiber has great significance.Though the development and the production of carbon fiber has obtained certain achievement, conclusively, it is still at a low level which is equal to the level of 1970 ' s abroad. The production capacity of the pitch carbon fiber is on a small scale, though the research in out country is carried out for a long time from the beginning, there are great gap compared with the foreign countries in the research and production application.The development of the pitch carbon fiber precursors can be made by refining and modulating asphalt, it must be carbonized, and then it can become the pitch carbon fiber. This paper discussed the part of the silk collection, a device for accepting silk, it not only can accept the kilometer pitch carbon fiber, but also can run stably.The silk collection control system used closed loop control scheme. PLC had become the kernel of the new control system and humanistic man-machine interface was designed as well.The system had achieved the expected target after the experiment, the kilometer pitch carbon fiber was developed and the system ran stably. At present, the carbon fiber had been used to practical application.The development of the kilometer pitch carbon fiber filled a domestic gap in this field and had a great significance to the research and production of the carbon fiber.
