Abstract

The invention relates to a continuous process for coating bundles of fibers, particularly carbon fibers, with a layer of silicon--which may be present as the carbide, oxide, nitride, or plasma polymer with carbon and hydrogen or in elementary form--by radio-frequency sputtering. The coated fibers are suitable in particular for the manufacture of reinforced plastics.
