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