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.
Claims15
A method for manufacturing coated short fibers, comprising:
- introducing a short fiber bundle having a coating or a fiber-containing plastic matrix into a reactor;
- exposing said coated short fiber bundle or said fiber-containing plastic matrix to a microwave field which breaks down the coating or the plastic matrix, thereby separating the fiber bundle or fibers in said fiber-containing plastic matrix into individual fibers;
- and
- coating the individual fibers on all sides by chemical vapor deposition with at least one coating agent present in the reactor as a gas, thereby forming a coating on the individual fibers.
