- Hot forming and press hardening (direct hot forming) or in the course of press hardening (indirect hot working) takes place, wherein the microstructure of the at least austenitized region of the steel sheet is converted by rapid cooling in a martensitic and / or bainitic structure, wherein the achievement of a martensitic microstructure is particularly preferred ,
- Notch which can be formed zacken-, laschen-, collar and / or crown-shaped, serves to connect at least one second material.
- the inventive method further comprises, which is provided as a second material plastic, which is connected at least for partial stiffening of the fully or partially hardened steel workpiece.
- fiber-reinforced plastics are used, in particular with glass, carbon and / or natural fibers, especially with biodegradable fibers offset plastic systems, depending on the type of fiber influence on the level of strength and rigidity of the plastic can be taken, in particular by the proportion of fill content.
- biodegradable plastic systems plastic matrix impregnated natural fibers are in Complete connection with steel materials and therefore environmentally friendly recyclable.
- the plastics used or preferably fiber-reinforced plastics are temperature-stable up to at least 200 ° C., in particular KTL-resistant. If fibers are considered, these are also up to at least 200 ° C
- Notching hardened The notch is formed in the course of the hot forming by means integrated in the tool, which are coordinated so that they quickly withdraw heat after the indentation of the notch and cause hardening, whereby a further deformation of the notch is no longer possible.
- the notch can not be hardened. This can be accomplished with the same means as in the tool hardening, but with the difference that the notch means substantially remove no heat, particularly when the notch means are formed or tempered or actively heated from a poorly conductive material are.

- the length of the notch is chosen such that at least a portion of the notch, after the two materials were merged, survives, which in a further step in parallel with contact to the plastic for positive connection (cold), in turn, is changed by 90 °.
- the plastic is already preformed and in particular fiber-reinforced, which corresponds to the geometry and dimension, in particular as an exact fit
- Plastic molding is provided to be connected to the steel workpiece and to give him at least partially a higher strength.
- the hardened notch is formed according to an alternative embodiment of the method according to the invention in the course of hot forming at an angle of in particular less than 90 °, preferably less than 60 ° and more preferably less than 45 ° from the plane of the steel workpiece.
- connection is made with a plastic, wherein the fully or partially hardened steel workpiece is inserted into a second tool, in particular in an injection mold and the steel workpiece at least in the notch with liquid plastic molded and / or injected behind. Due to the preferably angular orientation (acute angle) of the Ausklingung a kind of undercut is provided, which ensures a permanent connection to the steel workpiece especially after curing of the plastic, preferably the fiber reinforced plastic and gives it at least partially a higher strength.
- the invention relates to a component comprising at least two different materials, which has a fully or partially hardened steel workpiece, which has at least one notch, via which at least one second material is connected, wherein the second material for at least partial stiffening of the steel workpiece from Plastic is formed.
- the invention relates to the use of a previously described component as crashrelevantes component in the vehicle, in particular as A, B-C, D-pillar, side members and / or cross member. To avoid repetition, reference is made to what has been said.
