This project deals with the manufacturing and subsequent treatment of partially strengthened, three layered, symmetrical sandwich structures. Those sandwich materials have the advantages to combine the properties of the used mono‐materials. Additionally, they have a good damping behaviour because of the soft core and good stiffness and a good corrosion resistance if stainless steel sheets are used as cover. The characteristics of such structures are even more improved by the specific local influence of partial reinforcement within the sandwich material. With this type of strengthening, complex material properties can be developed, e.g. high strength with high stiffness, good thermal joining properties at the place of strengthening, as well as an improved strength and strength absorbing ability. The forming behaviour of such composite materials is still unknown. In this research project different sandwich materials ‐ with and without reinforced elements ‐ are analysed in bending tests and in deep‐drawing investigations.
