Method for producing a vehicle component from a fiber-reinforced plastic

A method for producing a vehicle component from a fiber-reinforced plastic, the method comprising:

• providing at least one skin panel having an inner side, an outer side and a mounting portion on the inner side, wherein the skin panel comprises a fiber-reinforced thermoplastic material;
• providing at least one stiffening component having a connection surface, wherein the stiffening component comprises a fiber-reinforced thermoplastic material;
• contacting the at least one stiffening component and the at least one skin panel such that the connection surface lies on the mounting portion, such that the mounting portion of the at least one skin panel is in flush areal contact with the connection surface of the at least one stiffening component;
• areally warming a joining zone in which the connection surface of the stiffening component and the mounting portion are situated such that the at least one stiffening component and the at least one skin panel are combined by being welded to one another;
• cooling the joining zone;
• comparing a determined geometry of the combined stiffening component and skin panel with a predefinable geometry;
• and
• re-warming the joining zone, deforming the stiffening component and/or the skin panel, and cooling to attain the predefinable geometry when the determined geometry deviates from the predefinable geometry.
