Carbon Fiber Preparation Method

- Apr 15, 2019-

The industrial production of carbon fiber can be divided into polyacrylonitrile (PAN)-based carbon fiber, pitch-based carbon fiber and viscose-based carbon fiber according to the raw material route, but mainly produces the first two carbon fibers. High-mechanical carbon fiber prepared from viscose fiber must be graphitized by high temperature, low carbonization yield, technical difficulty, complicated equipment, high carbonization yield of raw materials, but due to complicated preparation of raw materials and low product performance. It has not been developed on a large scale; the high-performance carbon fiber made from polyacrylonitrile fiber has a simpler production process than other methods, and its output accounts for more than 90% of the total global carbon fiber production.
