Cover Story Automobile Construction

Harmful emissions from motor vehicles can be lowered by combining new process technologies with smart material systems a direct optimisation of technical systems. In the automotive application as a wheel a direct improvement in driving characteristics is also achieved by reducing the unsprung weight. Through the focused utilisation of material-side benefits in the composite material, the lightweight construction wheel puts a symmetric sandwich with aluminium foam core and cover layers made of thermoplastic fibre-reinforced plastics as a structural element in application.

The specific combination of different materials and the associated manufacturing process for production of a functional hybrid network enables the fulfillment of increasingly complex requirements for components used in mechanical, economic and ecological characteristics. Therefore, such hybrid systems are currently of high scientific and industrial interest and earn in many technical applications increasingly...
