MATERIAL DE AMORTECIMENTO DE VIBRAÇçO DE TIPO COMPàSITO DE RESINA LIVRE DE CROMATO EXCELENTE EM LIGABILIDADE DURAVEL. A presente invenção refere-se a um material de amortecimento de vibração de tipo de compósito de resina livre de cromato excelente em ligabilidade durável tendo uma estrutura de múltiplas camadas constituída de uma composição de resina viscoelástica intercalada entre chapas de metal como uma camada intermediária, caracterizado pelo fato de que: (i) a composição de resina viscoelástica é uma resina de termo- endurecimento constituída de uma resina de poliéster copolimerizável amor- fa e um agente de cura e (ii) as superfícies das chapas de metal sobre os lados que contatam a camada de resina viscoelástica são providas com bases de ligação livre de cromato compreendendo de 5% em massa a 50% em massa de sílica, de 5% em massa a 50% em massa de uma resina de poliéster, de 1 % em massa a 50% em massa de ácido tânico, e de 0% em massa a 30% em massa de um agente de acoplamento de silano.
