Porsche debuts braided carbon wheels.
Porsche is now offering lightweight wheels made with advanced technology and braided carbon fiber. Available as an option for the Porsche 911 Turbo S Exclusive Series, the wheels are 20% lighter than standard alloys with a set of four wheels weighing only 8.5 kilograms.
To bring out their unique construction, they are protected by a layer of clear lacquer that highlights the carbon fiber construction. Due to the wheels’ lower unsprung weight, the car’s tyres will trail the surface of the road better and will be more capable of absorbing longitudinal and lateral forces. And lower rotating masses mean more spontaneity in acceleration and braking. The outcome is better driving dynamics and enjoyment, according to the German car maker.
The braided carbon fiber wheels are manufactured entirely from carbon fiber reinforced polymer (CFRP) using a two-component construction. A wheel center is made from carbon-fiber fabric, which requires cutting and assembling of over 200 components. The rim base is made from braided carbon fiber. The two components are braided together using what Porsche says it the largest available carbon fiber braiding machine. The braiding technology creates a material structure that is considerably more dense and compact with increased rigidity.
The assembled wheel is impregnated with resin and hardened with high pressure and high temperature. Available at the beginning of 2018 in size 9 J x 20 for the front axle and 11.5 J x 20 for the rear.
