Abstract : A technique is reported for temporarily plasticizing high modulus carbon fibers, which offers promise for permitting familiar textile operations to be carried out on them without mechanical damage. The technique consists of exposing the carbon fibers to a suitable intercalating material, such as liquid bromine or iodine monochloride. These materials have the effect of plasticizing the fibers, lowering their moduli. In the plasticized state, the fiber yarns are appreciably more flexible than in their unplasticized state, and the yarns can be made to take shapes which would cause the unplasticized material to break. On removal of the plasticizer, the yarn will retain a portion of the shape imparted to them. (Author-PL)
