Abstract:
Multilayer composites consist of viscoelastic polymers laminated between two metal “skins”. The polymeric core in the composite is subjected to shear, thus absorbing the incoming mechanical energy which is then dissipated as heat. This entire process acts to prevent generation of noise.These vibration damping composites are commercially more attractive because they can now be made by a continuous process in coil form rather than by the conventional, non-continuous laminating press procedure.
