Vibration damping composite laminate

摘要: Disclosed is a vibration damping composite laminate of the type comprising viscoelastic polymer composition layer interposed between two layers metal, which high in effectiveness and can readily be spot-welded to metal structures. Essentially blend polyvinyl acetal resin particulate carbon amounts 10-80 wt % composition, on condition that ratio mean particle size thickness from 0.5 1.7. Optionally may further comprise polyolefine and/or plasticizer.
