Laminated glass structures with optical clarity and methods for making the same

A laminated glass structure, comprising:

• a non-glass substrate comprising a high pressure laminate (HPL), an upper primary surface and a lower primary surface;
• and
• a flexible glass sheet having a thickness of no greater than 0.3 mm laminated to the upper primary surface of the non-glass substrate with an adhesive,
• wherein the non-glass substrate comprises an upper moisture barrier at a selected depth from the upper primary surface, the moisture barrier having a thickness from about 20 microns to about 60 microns,
• wherein a total thickness of the non-glass substrate, the flexible glass sheet and the adhesive is from about 4 mm to about 25 mm, and
• further wherein the adhesive is substantially defect free upon exposure of the laminated glass structure to (a) a drying evolution at 70° C. for 15 days;
• and (b) ambient humidity and temperature for 60 days.

A method of making a laminated glass structure, comprising the steps:

• preconditioning a non-glass substrate at 70° C. for at least 96 hours to define a preconditioned, non-glass substrate, the non-glass substrate comprising a stack of polymer-impregnated papers and an upper moisture barrier, and having an upper primary surface and a lower primary surface;
• and
• laminating a flexible glass sheet having a thickness of no greater than 0.3 mm to the upper primary surface of the preconditioned, non-glass substrate with an adhesive to form the laminated glass structure,
• wherein the upper moisture barrier is at a selected depth from the upper primary surface of the preconditioned, non-glass substrate.
