MULTIM - Challenges using multi material design
Purpose and goal
The aim of the project has been to develop guidelines, competence and solutions for multi-material design. A material for to guide design engineers and product developers has been produced. There has been a large exchange of expertise between different industries throughout the project. The project has produced four demonstrators that highlight both problems and solutions for multi-material design: Spare wheel housing, outlet guide vane, guide bar, crash box and back plate.
Expected results and effects
The type joints that have been dealt with in all four multi-material design cases are considered theoretically possible to implement in production. What needs to be investigated in the future is cost reduction and stability/automation of the processes involved. The project has developed expertise in the form of guidelines and an educational material, in addition to the direct project discussions.
Planned approach and implementation
Participating partners has been Swerim, RISE, Volvo Cars, Gestamp, GKN, Husqvarna and SSAB.The project has studied four types of joints linked to four industry relevant cases. The joint types have been combinations of steel, aluminum, CFRP and titanium. From each case, competence has been extracted and shared in a common forum, which has led to a greater exchange of competence between different branches of industry. Surprisingly many similar problems have existed between the industries.
