Affordable Multi-Material Lightweight Design - Selected Results of the H2020 Project ALLIANCE

In the last years, the research activities in the field of lightweighting have been advancing rapidly. The introduction of innovative materials and manufacturing technologies have allowed significant weight reduction. Despite this, novel technologies and materials have not reached a wide distribution. The reasons for this are mainly high production costs and environmental impacts of manufacturing that do not compensate benefits during operation. The paper will discuss selected final results of the H2020 project AffordabLe LIghtweight Automobiles AlliaNCE (ALLIANCE, www.lightweight-alliance.eu) which has the goal of developing novel advanced automotive materials and production technologies, aiming at an average 30% weight reduction over 100k units/year, at costs of < 3 â¬/kg-saved. An o verlook of the realized demonstrators will be given and the applied new materials and manufacturing technologies discussed. A special focus will be put on how the different concepts, materials and manufacturing technologies have been evaluated regarding GWP and costs.
