Abstract
The invention provides a process for carbonization production of pre-oxidized fiber fabrics. The process comprises the following steps of: spinning and weaving spinnable pre-oxidized fibers to prepare the pre-oxidized fiber fabrics, and performing carbonization treatment of the fabric so as to convert the fibers into the carbon fiber fabrics having a disordered-layer graphite structure. The carbon content of the pre-oxidized fiber fabrics carbonized by the process is 80 to 90 percent. By the carbonization process of the pre-oxidized fiber fabrics, the high-carbon content carbon fiber fabrics, which are widely used for sporting goods, fireproof materials and even low-weight high-strength materials for aviation and spaceflight, civil use and the like.
