Due to their light-weight potential, fiber-reinforced plastics (composites) are used increasingly frequent in cars. The challenge herein lies in the fulfillment of the suitability requirements for use in large production series. The aim of the present work was to develop a new matrix system, which enables an efficient production process by using a prepreg pressing process for the manufacture of structural automobile components. For this purpose, a new hybrid matrix of polyurethanes and polymethacrylates was formulated, with which the fibers can be impregnated solvent-free at room temperature. Semi-finished products (prepregs) produced in this way are storage stable at room temperature, enable rapid processing and allow to produce components with thermosetting material properties. In addition, topics such as solution-viscosity, storage stability and reactivity were discussed using the pure matrix investigations and the structure-property relationships as well as the influences of the reaction conditions on the thermal and mechanical properties of the material were considered. The here presented results show that by comparison with reference materials, which are already used for structural components in the automotive industry, the final material properties of the new laminates are comparable to commercial epoxy resins with the same fiber reinforcement after fully curing. In addition, the new hybrid system shows significant advantages in its processability.
