Abstract (Englisch)

During the last decade fundamental research on smart structures using intelligent materials has raised industrial interest in applying these results to many problems found in commercial and civil life. The main objective of smart structure technology is noise and vibration reduction in civil engineering, machine tools, automobiles, trains, and aerospace engineering. Both strongly coupled phenomena limit the design of highly advanced and efficient lightweight structures, whereby nowadays noise is considered one of the worst forms of environmental pollution worldwide. Beyond their impact on noise, intelligent material systems will for the first time allow for a concurrent lightweight design that enables the efficient use of natural resources in the product itself (less fuel consumption, less exhaust emission,. ..). With the upcoming demand of highly efficient, emissionless lightweight structures and increased standards for any type of emission, new intelligent materials systems are needed that allow for highly damped and controllable as well as light but durable structures for any type of high- tech application, most importantly, are not yet included in standard design and manufacturing processes.
The objective of the proposed Integrated Project, 'Intelligent Materials for Active Noise Reduction (InMAR)' is the research and realization of intelligent, high-performance, adaptive material systems with integrated electronics for different individual applications. These are applicable for noise mitigation purposes - even in highly loaded structures as construction material - in the same manner that common passive or lightweight materials have been used up to now.
