ABSTRACT:
An improved method of manufacturing articles containing carbon fibers when the fibers are temporarily plasticized to render them more flexible thereby permitting tortuous mechanical manipulation of the fibers to be carried out with little or no mechanical damage. The improvement comprises exposing the carbon fibers to agents capable of intercalating single crystals of graphite, such as bromine or iodine monochloride which have the effect of plasticizing the fibers by lowering their tensile modulus. While the fiber yarns are appreciably more flexible in the plasticized state, and have a higher elongation-at-break, on removal of the plasticizer they tend to return to their original state but retain a measurable degree of the shape imparted to them.
