The invention relates to a method for producing a material composite composed of metal and plastic to form a plastic-metal hybrid component, in which method, to improve the adhesion of the metal surface and at least one plastic component, stochastically random macroscopic and/or microscopic undercuts are made by means of short-pulse laser radiation in the metal surface in order to roughen it, these undercuts each being filled at least partially with the at least one plastic component in an injection moulding process such that said plastic component engages into the macroscopic and/or microscopic undercuts, wherein, following the roughening of the metal surface and before and/or during the injection moulding process for the at least one plastic component, at least the roughened surface of the metal is heated to a temperature which, during processing, lies in the range of room temperature up to 100&#xb0; C. above the processing temperature of the plastic.

Method for producing a material composite composed of metal and plastic to form a plastic-metal hybrid component

A composite part is produced by a process in which at least one of components a) and b) of said composite part is treated with an Openair plasma on a contact surface between said components a) and b) prior to production of the composite part, followed by molding-on of the other component; wherein said components are as follows: a) a part which entirely or to some extent comprises a molding composition comprising at least 40% by weight of a polyamide whose monomer units contain an average of at least 8 carbon atoms, and b) a part comprising another molding composition.
