ABSTRACT:
A method for manufacturing coated short fibers, in which the short fibers are coated in a reactor with at least one coating agent. The method includes exposing a short fiber bundle having a coating or a plastic matrix to a high-frequency field which dissolves the coating or the plastic matrix. The fiber bundle is separated into individual fibers and are coated by chemical vapor deposition on all sides by at least one coating agent present in a gas phase. A combination of mechanical and microwave treatment is preferably provided to loosen the short fiber bundles.
