Research progress of graphitization of carbon fibers
摘要
Abstract
The graphitization of carbon fiber can make its structure gradually evolve into the ideal graphite structure with a significant increase in the tensile modulus, so the graphitized fibers have been extensively used in cutting-edge fields such as aerospace. In order to give some references to the fabrication of high modulus carbon fibers, this paper compared the strengths and shortcomings of graphitization equipment, and introduced several new graphitization methods including ultra-temperature heating via laser and the relevant process of promoting graphitization in detail. Moreover, some factors affecting the mechanical properties were analyzed based on the microstructure. It is proposed that the main graphitization technique of indirect heating of graphite body cannot further increase the modulus due to the temperature limitation, so the technique that is able to overcome the temperature limitation as well as having the advantages of high performance, high quality, energy saving and environmentally friendly should be developed in the future. In addition, the structure evolution analysis of the carbon fiber should be placed on the molecular level. Then the control of graphitization process and the design of the modified equipment should be further optimized, so that the structure of the graphitized carbon fiber can be continuously improved and its mechanical properties can approach the theoretical value.关键词
