Porsche braided carbon fibre wheel…..worlds first!

Manufactured entirely from carbon fibre reinforced polymer (CFRP), the wheel is essentially comprised of two components. The wheel centre is made from carbon-fibre fabric. This involves cutting and assembling over 200 individual components. The second component is the rim base made from braided carbon fibre by what is currently the world’s largest carbon fibre braiding machine with a diameter of approximately nine metres. The wheel centre is then braided into the rim base. The assembled wheel is impregnated with resin and pre-hardened at high pressure and high temperatures. The finished wheel is hardened at high temperatures followed by a long cooling process. The central lock is then inserted into the finished wheel and the wheel is protected with clear lacquer.

Porsche is the first company in the global automotive industry to use this extremely complex technology. The braiding technology offers key advantages over the more conventional method of manufacturing pre-impregnated carbon-fibre fabric: This production technique makes the material structure of the carbon considerably denser and more compact. This increases rigidity. Using the material more efficiently also produces less waste. The new carbon wheel is made from a total of 18 kilometres carbon fibre or eight square metres of carbon-fibre fabric.

From the beginning of 2018, the new carbon wheels will be available as an option for the 911 Turbo S Exclusive Series in the dimensions of 9 J x 20 for the front axle and 11.5 J x 20 for the rear axle. In Germany, the price will be EUR 15,232 including VAT which is about USD17,000.
