– Suspension springs of potion fiber-reinforced polymer instead of steel
– For some-more accurate driving: 40 percent weight savings  
– Market launch in tumble 2014

Audi bringing new lightweight springs to prolongation models. Audi is reinforcing a heading purpose in automotive lightweight construction. The association is introducing new, lightweight cessation springs done of potion fiber-reinforced polymer (GFRP) in an top mid-size indication before a finish of a year. 

The GFRP spring, that Audi grown in partnership with an Italian supplier, even looks opposite than a steel spring. It is light green, a fiber strand is thicker than a handle of a steel spring, and it has a somewhat incomparable altogether hole with a revoke series of coils. Most importantly, however, it is some 40 percent lighter. Whereas a steel open for an top mid-size indication weighs scarcely 2.7 kilograms (6.0 lb), a GFRP open with a same properties weighs usually approximately 1.6 kilograms (3.5 lb). Together a 4 GFRP springs so revoke a weight by roughly 4.4 kilograms (9.7 lb), half of that pertains to a unsprung mass. “The GFRP springs save weight during a essential plcae in a framework system. We are therefore creation pushing some-more accurate and enhancing vibrational comfort,” pronounced Dr. Ulrich Hackenberg, Member of a Board of Management for Technical Development during AUDI AG. 

The core of a springs consists of prolonged potion fibers disfigured together and assimilated with glue resin. A appurtenance wraps additional fibers around this core — that is usually a few millimeters in hole — during swapping angles of and and reduction 45 degrees to a longitudinal axis. These tragedy and application plies jointly support one another to optimally catch a stresses behaving on a component. In a final prolongation step, a vacant is marinated in an oven during temperatures of over 100 degrees Celsius.

The GFRP springs can be precisely tuned to their particular task, and a element exhibits superb properties. It does not corrode, even after mill chipping, and is cool to chemicals such as circle cleaners. Last though not least, prolongation requires distant reduction appetite than a prolongation of steel springs.
