Abstract
A method is provided in which suitable carbon-fiber scrap is fed, together with a plastic polymer, to a pulverizer and extruder in order to produce a carbon-fiber polymer mass therefrom and to impregnate the mass with a resin. A regrind prepreg, which is given suitable forms and/or lengths, is thus obtained. The regrind prepregs thus obtained can then be given an approximately final form in an additional step by way of an extrusion process.
