VIBRATION DAMPING ARTICLE AND METHOD OF USING SAME TO DAMP VIBRATION

摘要

A vibration damping article includes a) a substrate having a density of at least about 10 lb/ft<3> and a flexural modulus of at least about 110,000 psi; and b) a foam layer bonded to said substrate, said foam layer having a loss tangent of greater than about 0.2 in the range of 10 to 20,000 Hz and a compressive storage modulus of from about 10<5> dynes/cm<2> to about 10<10> dynes/cm<2> in the range of 10 to 20,000 Hz.
