Abstract
A treated carbon fiber tensile cord for use in power transmission belts, hose, tires or other reinforced rubber products and the resulting product, which includes carbon fibers which are coated with a polymeric layer deposited and polymerized at atmospheric pressure in a plasma assisted chemical vapor deposition process. A suitable polymeric layer is compatible with the intended matrix which the cord will reinforce. For a rubber belt, the coating is compatible with the rubber composition of the belt body or an adhesion gum or adhesive such as RFL which surrounds the cord. For RFL/rubber systems and cast polyurethane elastomers, a suitable polymer is the APP reaction product of a vinyl carboxylic acid or an ester or amide thereof. Suitable carboxylic acids include acrylic acid and methacrylic acid. Various esters and amides of vinyl carboxylic acid are also suitable, such as 2-hydroxyethyl methacrylate, N-isobutoxymethyl acrylamide, and N-hydroxyethyl acrylamide.
