Abstract : The formation of high modulus and high strength graphite fibers from polymeric fibers and from fibers spun from pitches is reviewed. Methods of preparation given by patents and in the technical literature are abstracted for precursors including cellulose or rayon, polyacrylonitrile, PVA, PBI, and aromatic polyamide yarns. The properties of the graphite fibers are given and relationships between various properties and methods of preparation are cited where these exist. (Author-PL)
