World premier: First Carbon series roof for Audi RS5

First Carbon series roof for Audi RS5

Wethje Carbon Composites GmbH based at Pleinting in Lower Bavaria succeeded in marking a world premier with the new PCM-technology: The first time a series vehicle will be equipped with a carbon roof.

The PCM-technology stands for Prepeg Compression Molding and has been developed by Mitsubishi Chemical Cooperation. The material (Prepreg) is being supplied as rolls. In the partproduction-process several layers are being laid on top of each other, resulting in a so call “stack”. This one is then being processed to Pre-Forms. Subsequent these goods are being pressed to a carbon roof with a 2-parts-tooling. Finally parts like internal protection and antenna are being mounted at the carbon roof after clear coat painting.

This innovative technology is in many ways ground-breaking:

  • The fast hardening material, which was especially optimized for the PCM-technology, reduces the production time from several hours to a few minutes. This reduction of production cycle time involves a significant cost reduction.
  • Excellent mechanical properties in combination with an appealing look give the product weight reduction of 40 percent compared to the aluminium execution
  • This reduction lowers the gravity of the car, which has a positive effect to the driving characteristics and the sustainability.

With this Wethje Carbon Composites GmbH starts series production. Managing Director Florian Anzeneder is very pleased: “Thus we succeed the claim of our costumer which is commonly known as “Vorsprung durch Technik” getting a step forward.”
