.
.
As drivers become passengers, they need a flexible interior compartment to accommodate new activities, such as working on the go
.
A consortium of three parties, Covestro, Engel of Austria and Dr.
Schneider, has developed a thermoplastic composite solution for a lightweight yet mechanically strong, foldable table to meet such demands during autonomous driving
.
.
It's designed so that it can be stowed between the rear seats to save space
.
.
Its top and bottom are made of 1 mm thick Maezio® polycarbonate composite and reinforced with continuous carbon fiber
.
The sandwich core is a rigid low density polyurethane foam based on Baydur 20
.
Both materials come from Covestro
.
The table weighs about 690 grams and is less than 1 cm thick, making it very thin and yet very strong
.
It can carry 50kg, while the maximum load case for a normal injection molded table of this size is 5kg
.
.
After heating, the soft semi-finished product is transported by the Engel Easix articulated arm robot to the duo 350 injection moulding machine and transferred into the opened injection mould
.
With the injection molding machine closed, the composite material is cooled after molding
.
.
Covestro designed the components, checked the adhesion properties of the PUR foam, carried out CAE simulations of the load cases, and determined the direction of loading of the fiber fabric layers
.
In addition, the overhang of the composite insert in the tool was simulated to optimize production
.
.
Dr.
Schneider has developed a tool for composite molding with variable temperature control that ensures flawless surface quality of parts
.
Additionally, the tool is designed in such a way that the inserts are placed evenly on the tool walls without creases
.
.
But to achieve this, we need a very strong partner relationship, and that’s what we’ve built with these two partners to enable the industry to adapt to future mobility trends
