Abstract : The patent concerns a method of enhancing the tensile strength of carbon fibers of laboratory and commercial materials. Carbon fibers are immersed at ambient temperatures in liquid bromine or bromine dissolved in a solvent within a chemical resistant container for a period of time. The bromine is then removed by flushing with an inert gas. The bromine may be recovered and reused by condensing the vapor; small traces of bromine may remain within the fiber. It has been found that the bromine treatment enhances the tensile strength of the treated fiber.
