“Multi-material designs : the new rules in automotive industry.”
Light weight & Mass reduction:
- Low consumption,
- Reduction of emissions,
- Autonomy improvement (In particular of electric vehicles),
Structural reinforcement & Architecture evolutions,
- Dynamic performances improvement
- Adaptation to new safety standards,
Reduction of numbers of parts,
- By using plastic or composite parts which enable to replace several metallic pieces into one
If the multi-material designs are a source of large optimization of the automotive performances, there implementation in practice is obstructed by technical assembly difficulties & economical issues.
The current fastening characteristics aren’t in line with automotive industry’s targets,
in particular the strong will of challenging the multi-material assembly …
_ without making big industrial investments,
_ without revolutionizing the organization of Body In White workshop.
