Its outstanding stiffness and strength open the door to new applications in automotive engineering for highly reinforced polyamide 6 as an alternative to sheet steel, aluminum and glass-mat-reinforced thermoplastics (GMT).
The plastic-metal composite technology invented by LANXESS, also known as hybrid technology, has become firmly established in the automotive industry for the manufacture of lightweight, high-strength structural parts such as front ends, pedal support brackets and brake pedals.
The lower beam of the front end of the new Audi A8 features a U-shaped profile made of organic plastic sheet. The front end proves that organic sheet meets all the requirements relating for instance to torsional and flexural strength. It is an excellent alternative to steel and aluminum sheet in hybrid technology. (Photo: LANXESS)
The organic sheet reinforcement for the lower beam is just 1.0 mm thick. When the car is out on the road, the part is subjected to considerable loads because the lower beam carries, among other things, the lower leg protection, the bumper, the underbody protection and the fixing point for the cooling module.

Durethan DP BKV 60 H2.0 EF enables precise injection molding of the spare wheel recess’s complex geometry. The polyamide 6 also allows direct integration of numerous functions. It would be very difficult to make the component from sheet metal due to the limited space available and the high draw ratios. (Photo: LANXESS)
In addition to its principal function, the spare wheel recess also reinforces the rear end of the car. This is achieved by integrating two reinforcing channels, each around two meters long, into the component using gas injection technology (GIT). (Photo: LANXESS)
