摘要
A method for selecting a viscoelastic plastic interlayer including two outer layers and a central layer. The interlayer is for incorporation between two glass sheets of a glazing unit. The method of selection includes providing first and second components respectively as the central layer and the outer layers, and measuring the shear modulus G′ of the first and second components. The material of the second component is selected only if G′ is a certain value at a specific temperature and frequency range. The thickness h of the first component is set so that h is a specific value and so that g=G′/h is within a specific range of values at a specific temperature and frequency range. The method optimizes the damping of the second and third natural frequencies of a vehicle windshield without weighing down the windshield.
