A key success factor to fulfill the increasingly stringent climate protection guidelines is the consistent pursuit of lightweight construction strategies. One promising approach here has been the usage of multi-materials or hybrid lightweight constructions, in which different materials are used within a specific structure or component. For a long time no great importance was given to wood as a structurally relevant component. Due to its mechanical characteristics, however, wood has a very high lightweight potential and also has numerous other advantages. These include good sound and heat insulation, an attractive price compared to other structure-relevant materials and very good local availability, even in large quantities.
The project "For(s)tschritt" has the TÜV Rheinland as project sponsor and is promoted by the Federal Ministry for Economic Affairs and Energy (BMWi) over a period of three years. Nine partners from industry and science have joined forces to explore the lightweight potential of wood in combination with metallic materials and fiber reinforced plastics. For this purpose, wood-based multi-material systems are characterized for the creation of simulation models. In addition, structurally relevant assemblies for rail and road vehicles are also manufactured and tested as demonstrators.
The Institute of Vehicle Concepts of the German Aerospace Center with its department "Material and Process Applications for Road and Rail Vehicles" is specialized in transferring new and complex material and process solutions to innovative applications based on a comprehensive understanding of "vehicles". As part of the "For(s)tschritt" research project, DLR supports the project partners in the entire product development process, from conception, design and simulation through to testing and final evaluation.
