LAMINATED GLASS STRUCTURES WITH IMPROVED WAVINESS

A laminated glass structure is provided that includes: a substrate comprising a primary surface and a thickness from about 0.5 mm to about 50 mm; an adhesive having an elastic modulus, Eadhesive, of about 0.001 MPa to 0.2 MPa; and a flexible glass sheet having a thickness, tglass, of no greater than about 300 μm. The flexible glass sheet is laminated to the primary surface of the substrate with the adhesive. Further, a thickness of the adhesive, tadhesive, IS given by the following: tadhesive>δ×AWt×(200\imltglass)×(Eadhesive 10.1 MPa), where δ is a waviness constant set at 150 and AWt is a delta total waviness (μm), the delta total waviness, AWt, ranges from about 0.125 μιη to 2.5 μιη and is defined as the difference between a waviness of the substrate and a waviness of the glass sheet.
