Patent

CA 2218513

The present invention provides a blow spinning die particularly suited for spinning solvated pitch into fibers having a random cross-sectional structure. Additionally, the present invention provides a process for blow spinning fibers from solvated pitches. The present invention also provides pitch fibers having a high energy internal molecular structure. Finally, the present invention provides carbon fibers which have a non-radial internal structure.

L'invention concerne une matrice de filage par soufflage particulièrement conçue pour filer des brais solvatés et former des fibres présentant une structure de coupe transversale aléatoire. En outre, l'invention concerne un procédé pour assurer le filage par soufflage de fibres à partir de brais solvatés. L'invention concerne également des fibres de brai dont la structure moléculaire interne présente une énergie élevée. Enfin, l'invention traite de fibres de carbone qui présentent une structure interne non radiale.
