Continuous developments in car design and customer attention to performance and comfort have created necessities for improvements in external and internal noise reduction in cars, trucks and busses and thermal control around engine and exhaust areas. Solutions to the 'challenges' are usually combinations of novel designs and selection of more efficient engineering materials. The development of laminated composites consisting of outer metal 'skins' with a specially selected core material between them will be described. Depending on the noise damping and/or thermal insulation properties required by the application, the core may be viscoelastic polymers or inorganic materials. As the result of this development, 'families' of different materials for such applications are presented with the description of material properties and potential uses. These material systems include composites for noise reduction of parts in engine compartment, body parts, brakes, and materials for thermal control in under-the-hood, exhaust, and catalytic converter applications. Finite element design method, its application, prediction and correlation with other methods will also be presented. Manufacturability and processability of these materials together with practical applications will be addressed.
