Abstract
A method produces pellets from fiber composite materials suitable for further processing in a plastics finishing method. The pellets contain individual carbon fibers, carbon fiber bundles, or a mixture thereof and at least one thermoplastic matrix material. The carbon fibers, carbon fiber bundles, or a mixture thereof are isolated from waste or used parts that contain carbon fiber, laid flat together with the thermoplastic matrix material, compressed into a sheet material under the effect of heat, and subsequently cooled and comminuted into pellets, platelets, or chips. This enables the use of carbon fibers, from production waste components, as reinforcing fibers, whereby an inexpensive raw material is provided and the carbon fibers that are contained in the waste materials are recycled. The final carbon fibers are brought into a pourable and readily meterable form and can be used as raw materials for extrusion or injection molding for example.
