ABSTRACT:
Fibers having a high degree of flexibility and handleability are produced by oxidizing fibers spun from a carbonaceous pitch which has been transformed, in part, to a liquid crystal or so-called "mesophase" state to an oxygen content of from 17 per cent by weight to 30 per cent by weight. Because of their strength and handleability, these highly-oxidized fibers can be easily processed at high speeds by means of conventional yarn-transport systems, and readily woven or knit into cloth. Such cloth may then be heat treated to produce carbon or graphite cloth.
