    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.

    摘要： A windshield protection system has an optically clear sheet of plastic covering the windshield. The clear plastic sheet is attached to the windshield by a gasket around the perimeter of the windshield. A space is formed between the windshield and the clear plastic sheet. An optical matching material is used to fill this space. A valve in the gasket allows the optical matching material to be introduced into the space. The clear plastic sheet may have a hard coating. The clear plastic sheet protects the windshield from rocks that cause breaks, scratches and pitting. The optical matching material is a gel which increases the protection to the windshield and allows for variations in the shapes of windshields for other vehicles.
