ABSTRACT:
The invention comprises the use of a solution or extract of coal as a carbonaceous material to produce carbon fibers, filaments or films in a process comprising extruding or spinning the carbonaceous material to form a fiber, filament or film, oxidizing the spun or extruded carbonaceous material to stabilize it to further heat treatment, and carbonizing the stabilized carbonaceous material. Solutions or extracts of coal may be made by treating the coal with a high boiling aromatic solvent, for example anthracene oil or phenanthrene, at an elevated temperature, for example 400.degree.C.
