Abstract
Disclosed herein are a process for producing a carbon fiber mat, having excellent production and energy efficiencies, comprising successively melt-spinning a fiber-forming pitch by a centrifugal spinning machine having a horizontal axis of rotation (parallel to the plane on which the spinning machine is placed), forming a mat by the thus spun pitch fibers, bringing the mat into an infusibilized state in an air atmosphere containing NO.sub.2 and calcining the thus infusibilized mat in an inert atmosphere, and an apparatus for carrying out the above-mentioned process.
