Subject(s): Abstract: Projektet avser ett nytt tillvägagångssätt att pressa karosseriplåt. Metoden medger en sänkning av vikten utan att ge avkall på krocksäkerheten. Viktminskningen leder till sänkt bränsleförbrukning och minskade utsläpp av klimatgaser. Projektet stärker även samverkan mellan svensk bilindustri inklusive underleverantörer och högskolor.Abstract: The amount of ultra high strength steel in a car body structure is expected to increse in the future. The background to this development is the future environment requirements and the increasing safety regulations. By incresing the use of boron steels in the car structure, the crashwothiness can be improved and still, the weight of the car can be reduced which contributes to less discharge of CO2 gases. In this project, a process/tooling technology which makes is possible to manufacture products with zones with tailored material properties shall be developed. In this case, "tailored material properties" means that the mechanical properties of the material in the component is locally controlled in the process. The developed technology will make it possible to use hot formed boron steel in a large part of the car structure which is not possble today.
