Aircraft and Automotive lightweight sandwich structures
Genesis of Neenah product. Why and for whom?
For the team it was obvious that the breakthrough of the CFRP technology into a large scale production has to be prepared. Aim was a cost effective complex 2.5 D thermoplastic sandwich, with a very short cycle time of less than 5 min (aeronautic/AIRBUS) and less than 2.5 min (automotive/BMW)
Benefits for the final customers
Thermoplastic composites presecced by combined compression and injection molding enable the final customer to use a lightweight sandwich part, that can be produced in a one-shot process. Short cycle times and high degree of function integration allow ecenomic mass production.
The product: materials and processes
The part in manufactured in one machine and one mold. Endless fiber reinforced thermoplastic face sheets are thermoformed and joined with a foam-or fold.or rib-core without adhesive layer. Injection molding is used to add function integration like ribs and accurate edges: no rework is needed. Materials like PP/PA were used for automotive applications and PES/PEI/PEEK for aeronautic applications.
