Process for production of a composite

A process for production of a composite part, comprising:

• treating at least one of components a) and b) of the composite part by a plasma process on a contact surface between the components a) and b) prior to production of the composite, followed by molding-on of the other component;
• wherein:
• component a) is a part comprising a molding composition comprising at least 40% by weight of a polyamide whose monomer units contain an average of at least 8 carbon atoms;
• component b) is a part comprising another molding composition;
• and
• in the plasma process, a plasma is generated inside of a plasma chamber and then carried out of the plasma chamber and on to the contact surface.
