Design of polymeric materials for acoustic application#

 #

Multifunctionality is an increasingly important aspect in the design of materials. Engineering materials do not only need to perform in their mechanical function but also need to satisfy non mechanical or acoustic requirements. Within the context of a Fraunhofer internal project, polymeric materials with and without fiber reinforcement are developed and optimized with respect to their acoustic performance. For this purpose, the mechanical and acoustic response of microstructure of the materials is simulated numerically. Based on the results, customized material models are developed and implemented.
