| Résumé : |
The first series application of the lightweight material microsandwich in 2018 will reduce the weight of vehicle interior trim components by up to 50 %. The efficient one-shot process on existing manufacturing systems offers cost-effective component production by virtue of its short cycle times, as illustrated by the example of a door pocket. |
| Note de contenu : |
- Foam reduces areal weight
- Combination of material properties contributed by cover and core layers
- Sample application : Door pocket
