Abstract (en)
[origin: EP0458765A2] Disclosed herein is carbon short fiber characterized in that the fiber is made of one of those consisting of pitch-type optically isotropic carbon fiber, pitch-type optically anisotropic carbon fiber and the composite of the two carbon fiber, and is cotton-like. The carbon short fiber is cotton-like, curls and is twisted so that it possesses bulkiness, elasticity and stretchability. Accordingly, the fiber by itself or in combination with metal, ceramics and the like may be utilized in various fields as the material having excellent characteristics. Also disclosed is a process for preparing same. The process attains considerable economic effects by elevating the productivity because the pitch may be directly spun to the fiber. <IMAGE>
