THE ECONOMIC SIZE ANALYSIS OF PAN-BASED CARBON FIBER

There is a great market demard for PAN based carbon fibers (CF) in China. However, due to the smaller scale and inferior quality, the production of PAN based CF can not meet the application requirement and its profit is very low. The methods of economic scale are analyzed. Then based on the current technological conditions and selected two samples, the economic scale of PAN CF is estimated quantitatively by the method of engineering technology, which can be regarded as a guide to the industrial development of CF in China. It shows that the starting point of economic scale is between 200 tons and 275 tons per annum in China.
