摘要： The invention relates to a method for selecting a viscoelastic plastic interlayer including two outer layers and a central layer that can be incorporated between two glass sheets of a glazing unit, the method includes providing first and second components that constitute respectively the central layer and the outer layers, measuring the shear modulus G′ of the first and second components, selecting the material of the second component only if G′≧3×107 Pa at 20° C. and between 100 Hz and 240 Hz, and setting the thickness h of the first component so that h is between 0.31 mm and 1.20 mm and so that g=G′/h is between 5.58×108 Pa/m and 2.37×109 Pa/m at 20° C. and between 100 Hz and 240 Hz.

摘要： A viscoelastic plastic interlayer to be incorporated between two glass sheets forms a laminated glazing with vibro-acoustic damping properties. The interlayer includes at least one layer made of viscoelastic plastic with vibro-acoustic damping properties. The interlayer is tinted in the bulk at least on a part of its surface. The interlayer is such that the resonant frequency f2 of the second resonance mode of a laminated glazing bar with a surface area of 25 mm×300 mm composed of two glass sheets each 2.1 mm thick, between which is incorporated the interlayer, determined by measuring the mechanical impedance (MIM) at 20° C. according to standard ISO 16940, is between 760 Hz and 1000 Hz and the loss factor η2 of the second resonance mode of the same bar, determined by MIM under the same conditions, is greater than or equal to 0.25.

摘要： A viscoelastic plastic interlayer to be incorporated between two glass sheets forms a laminated glazing with vibro-acoustic damping properties. The interlayer includes at least one layer made of viscoelastic plastic with vibro-acoustic damping properties and particles having an infrared radiation-screening function. The interlayer is such that the resonant frequency f2 of the second resonance mode of a laminated glazing bar with a surface area of 25 mm×300 mm composed of two glass sheets each 2.1 mm thick, between which is incorporated the interlayer, determined by measuring the mechanical impedance (MIM) at 20° C. according to standard ISO 16940, is between 760 Hz and 1000 Hz and the loss factor η2 of the second resonance mode of the same bar, determined by MIM under the same conditions, is greater than or equal to 0.25.

摘要： A laminated glazing used as a head-up display screen includes two sheets of glass and a viscoelastic plastic interlayer arranged between the sheets of glass. The interlayer includes at least one layer made of viscoelastic plastic with vibro-acoustic damping properties. The interlayer has a cross section that decreases in a wedge shape from the top to the bottom of the glazing. A resonant frequency f2 of the second resonance mode of a laminated glazing bar with a surface area of 25 mm×300 mm composed of two glass sheets each 2.1 mm thick, between which is incorporated the interlayer, determined by measuring the mechanical impedance (MIM) at 20° C. according to standard ISO 16940, is between 760 Hz and 1000 Hz and the loss factor η2 of the second resonance mode of the same bar, determined by MIM under the same conditions, is greater than or equal to 0.25.
