Vibration damping resins containing epoxy blocks and vibration damped composites

摘要

Viscoelastic resins useful for forming vibration damped composites, i.e., metal layers adhered by the resins, contain only the elements hydrogen, oxygen and carbon and provide vibration damping over a wide temperature range. The resins are generally linear, high molecular weight polymers having blocks of epoxy and either polyester or polyether.
