FIBRE-REINFORCED COMPOSITE CONCEPT FOR A CONVERTIBLE ROOF MODULE
- 29 Downloads
Edag and BASF have jointly developed a convertible roof module with a fibre-reinforced composite sandwich design that offers high weight-saving potential compared to metal concepts. The demonstrator relies on custom-formulated, carefully matched material systems as well as production methods suitable for high-volume production thanks to short cycle times and justifiable costs.
For future urban mobility, vehicle mass will be a major factor, since it affects the energy requirement of both conventional and electrically powered vehicles. While rolling resistance and aerodynamics are also significant, their effects are of only secondary importance due to the numerous acceleration and braking phases that occur during normal operation in cities.
The pressure to implement new lightweighting concepts that go beyond what is currently being put into practice is increasing as car makers can expect fines if they do not achieve the ambitious CO2 limits coming in the future.
