Acoustically Optimized Structural Parts basing on Hybrid Fleeces

Dieter H. Mueller, Andreas Krobjilowski and Heidrun Schachtschneider


ABSTRACT

Composite materials with a reinforcement of natural plant fibers have successfully proven their high qualities in various technical areas. One of their major field of application can be found in structural interior elements such as door trim panels or trunk trims in the automotive industry. With respect to driving comfort the acoustical properties of such structural parts are considered more and more important. The paper covers extensive investigations on the acoustical properties of such composites and presents material designs for acoustical optimized structures.
