Abstract

A process for the production of fiber-reinforced components or semifinished products is provided, where fibers are saturated with monomer. The process includes at least one of adding flakes including fibers and adding individual fibers. For this, the fibers, the monomer, and the flakes including fibers and/or the individual fibers are added to an injection-molding machine and forced into an injection mold, whereupon polymerization of the monomer is completed in the injection mold. Alternatively a fiber structure on a conveyor belt is saturated with a solution including a monomer, optionally including an activator, and optionally including a catalyst. In a following step, individual fibers and/or flakes including fibers are distributed on the saturated fiber structure, the fiber structure is passed through a roll pair in which pressure is exerted onto the fiber structure, and finally the saturated fiber structure is cooled so that the monomer solidifies.
