FIELD: construction.
SUBSTANCE: material contains: a reinforcing metal layer, a polymer vibration-absorbing layer, made of thermoplastic polyurethane and an adhesive- from a polysulfide sealant or glue compositions on the basis of rubbers of a different chemical nature. The ratio of the thicknesses of reinforcing, vibration-absorbing and adhesive layers in the proposed material makes (3.0÷7.5):(5.0-25.0):1.0, accordingly.
EFFECT: improved damping properties of the vibration-absorbing material and expansion of temperature and frequency intervals of its operation with the reduced product weight.
