A method for treating carbon cloth with an aromatic disulfonic acid and the treated cloth produced thereby. The method comprises the steps of (1) wetting the carbon cloth (or fibers) with a molten disulfonic acid or a solution of the disulfonic acid; (2) drying the cloth by evaporation of the solvent, if a solvent is used, leaving the disulfonic acid behind to coat the fibers; (3) heating the disulfonic acid coated cloth to a temperature at which the acid can react with the surface of the cloth and/or with itself; (4) washing the coated cloth with solvent to remove any excess, unreacted disulfonic acid; and (5) drying the cloth by evaporating away the washing solvent. The cloth prepared by the above method is useful as a reinforcing material in composite structure.
