Abstract
The invention relates to sheet-shaped products processable by means of flow molding comprising carbon fibers and a radical-curable resin as the matrix, the fibers being present in the form of mats consisting of fibers with lengths of more than 1 cm and the volume percentage of the fibers relative to the resin being less than 70%, and the fibers moving freely relative to one another in the mat during flow molding, resulting in a net end product with a homogeneous fiber distribution. The invention also relates to a process for the production of sheet-shaped products by impregnating carbon fiber mats with a radical-curable resin and thickening that resin to a desired thickness, and a process for the production of molded parts with a tensile modulus of >20 GPa and a tensile strength of >200 MPa.
