Abstract : The patent application describes a process for temporarily plasticizing carbon fibers to render them more flexible thereby permitting textile operations to be carried out on them with less mechanical damage. The process comprises exposing the carbon fibers to suitable plasticizing materials such as bromine or iodine monochloride which have the effect of plasticizing the fibers by lowering their modulus. While the fiber yarns are appreciably more flexible in the plasticized state, and have a higher elongation-to-break, on removal of the plasticizer they return to their original state while retaining a portion of the shape imparted to them.
