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 G3×107 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.
