ABSTRACT:
Carbon fibers are electrocoated by electrodeposition or electropolymerization to facilitate the formation of char, a nonconductive residue or fiber clumps when the coated fibers within a composite are subsequently exposed to fire. Coating materials or precursors are phosphorus compounds, titanates, polyimides, polyquinoxalines, nitriles, or boric acid.
