Method for producing a vehicle composite component

A method for producing a vehicle composite component with a layer structure having a core layer in a molding tool, the core layer being formed with regions of different thickness, the method having the steps of:

• placing a cover layer onto a mold base plate of the open molding tool,
• introducing a first fiber layer, which is impregnated with PU resin and has not been subjected to forming, between the cover layer and a first mold counterplate of the open molding tool,
• closing the molding tool and compression molding the first fiber layer, which is impregnated with PU resin, against the cover layer, as a result of which a preform with a first support layer containing the first fiber layer is formed and hardened while supplying heat,
• opening the molding tool and replacing the first mold counterplate with a second mold counterplate with a highly structured mold surface,
• introducing a second fiber layer, which is impregnated with PU resin and has not been subjected to forming, between the preform arranged on the mold base plate and the second mold counterplate of the open molding tool,
• closing the molding tool and injecting foamable PU between the first support layer of the preform and the second fiber layer, the PU foam forming the core layer pressing the second fiber layer against the second mold counterplate, which has a profiled mold surface, and shaping it thereon as a second profiled support layer,
• opening the molding tool and removing the composite component formed.
