Morphing car body surfaces made of rubber for active aerodynamics control

The actual challenge for car developers is to improve the car handling combined with a reduction of CO2 emission. It is well known that car handling can be improved by increasing the down-force acting on the car. This can be optimised by optimizing the surface of the car body with respect to aerodynamics. However, generally speaking it will increase the air resistance and therefor the fuel consumption. The solution are active spoilering systems which can be adjusted in a well-controlled way. Because of its mechanical dynamic elastic properties rubber is the ideal material for car body surfaces which can be deformed actively during the ride. 
An active front spoiler is presented. The outside surface of the spoiler is made of rubber. Deforming the outside surface is done by means of inflating air bellows. As soon as the inflation pressure of the air bellows reduces, the rubber surface will return to its original shape by means of rubber elasticity. The presentation will focus on rubber technological issues to be solved during the development process.

Biobased tire performance and rubber process additives

The presentation will focus on two types of additives; process enhancement additives and tread enhancement additives.

The tread enhancement additives market has grown the last decade due to changed regulations. Arizona Chemicals tread enhancement additives show optimal performance balance between wet traction improvement, rolling resistance and wear resistance (magic triangle).

While gaining better tire properties, processability could become more challenging.

Process enhancement additives could be used to improve the processability without significantly impacting the improved tire properties.

Silica and silanes

The Tire Manufacturing Industry is technology driven and therefore the requirements to every single raw material in rubber compounds of tire formulations are high.

Evonik is the only silica supplier worldwide offering also rubber silanes. With this role Evonik continuously develops new products to meet the challenges. With the high surface area silica ULTRASIL® 9100 GR and the mercapto silane Si 363TM high tire performances can be reached.

Furthermore a look in the portfolio of Evonik shows that there is a wide variability of possible products and its combinations in order to fulfil the requests of the market.
