LAMINATED GLASS STRUCTURE WITH IMPROVED WAVINESS

Abstract:

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, E.sub.adhesive, of about 0.001 MPa to 0.2 MPa; and a flexible glass sheet having a thickness, t.sub.glass, of no greater than about 300 .mu.m. The flexible glass sheet is laminated to the primary surface of the substrate with the adhesive. Further, a thickness of the adhesive, t.sub.adhesive, IS given by the following: t.sub.adhesive>.delta..times.AWt.times.(200\imlt.sub.glass).times.(E.s- ub.adhesive 10.1 MPa), where .delta. is a waviness constant set at 150 and AWt is a delta total waviness (.mu.m), the delta total waviness, AWt, ranges from about 0.125 .mu..eta. to 2.5 .mu..eta. and is defined as the difference between a waviness of the substrate and a waviness of the glass sheet.
