In the project "SmartBatt" - funded by the EC under the 7th Framework Programme - a 20 kWh battery pack was developed which exhibits a 10-15% weight reduction as compared to the State of the Art. Besides an improved integration of the battery pack into the body-in-white a new sandwich material concept for the battery housing was used to accomplish this. Core of the innovative sandwich technology is to place polymer-coated aluminium foam granules between pre-moulded aluminium face sheets. Dedicated subsequent foaming of the polymer will result in a sandwich structure whose core layer consists of aluminium foam spheres embedded in a matrix of polymer foam. This approach allows excellent process control and the production of components with targeted local sandwich design. The mechanical properties of AlSi10-Epoxy hybrid foams were determined using quasi-static and dynamic compression tests and compared to the behaviour of epoxy-mono-foams.ensandwichhybrid foamaluminium-polymer compositeelectric mobilitybatteryfoam sandwicheselectric vehiclehybridaluminium620669journal article
