Abstract:
A method for producing a fiber-reinforced plastic outer skin component for a vehicle includes the following steps: a) providing a semifinished fiber product which includes at least one fiber layer with predetermined fiber orientation; b) applying an uncured plastic matrix in the form of an epoxy resin-based or polyurethane-based matrix system to the semifinished fiber product; c) placing the semifinished fiber product provided with plastic matrix into a mold; and d) pressing the semifinished fiber product in the mold in order to shape and cure the semifinished fiber product to form a fiber-reinforced plastic component. A shrinkage-reducing additive in the form of filler particles is admixed with the uncured plastic matrix and the uncured plastic matrix is applied to the surface of the semifinished fiber product that in the finished component faces the visible side of the component.
