Grazing with excellent vibro-acoustic damping behavior, method for producing such glazing, and method for acoustic protection of vehicle cabin

摘要

A glazing unit with an improved vibroacoustic damping property including at least one sheet of glass and at least one vibroacoustic damping strip that is attached to at least one of the faces of the glass sheet and that includes at least one component made of damping material having a loss factor greater than 0.2. The strip is not joined to any other device on the opposite side from the glass sheet and the component made of damping material has a Young's modulus greater than 800 MPa, at 20° C., for a particular frequency corresponding to the critical frequency of the glazing unit to within plus or minus 30%.
