Compositions of pitch, 1995 in the preparation of said compositions, the filament of pitch, of the said filament, carbon fiber based on pitch and method of preparation of the said carbon fiber

摘要

The invention concerns the manufacture of artificial textile products. / p & & p & the filament of a pitch which is the subject of the invention is characterizes in particular in that its structure comprises a multiplicity of lines or fibrils 2 of a constituent optically anisotropic, being managed in the axial direction of the filament and distributed in a matrix 1 of an optically isotropic fraction soluble in the quinoline. / p & & p & the filament of pitch is thus obtained is a final of carbon fibers, a pitch having a resistance to traction of at least 1.962mpa and a module for elasticity in traction of at least 98,1.10mpa.
