Others
The HyImpact energy absorber is designed as a first-class energy absorbing structure consisting of aluminium honeycomb covered in PU foam. It was jointly developed between Cellbond and BMW.
It was introduced as a C-pillar head impact countermeasure, but it can also be used in various occupant protection applications. The crush strength and shape can be designed to meet customer’s and legal requirements.
HyImpact
The foam used in HyImpact is an organic polyurethane material, which has been engineered to have a minimal density. This ensures that the foam does not modify the mechanical properties of the honeycomb in a significant way. Upon introduction into the honeycomb structure, the foam expands to fill each of the cells. The cells are fully filled by the foam and the excess saturates the fibrous cloth coverings thus protecting the foil edges, and providing a good surface for fixation in the vehicle.
