Abstract: A glass-polymer laminate structure includes a flexible glass substrate having a thickness of no more than about 0.3 mm. A polymer layer is laminated to a surface of the flexible glass substrate having a coefficient of thermal expansion (CTE) that is at least about 2 times a CTE of the flexible glass substrate. The polymer layer is laminated to the surface of the flexible glass substrate after thermally expanding the polymer layer to provide the flexible glass substrate with an in-plane compressive stress of at least about 30 MPa along a thickness of the flexible glass substrate.

Abstract: A laminated glass structure comprising a non-glass substrate and a glass sheet bonded to the non-glass substrate to form the laminated glass structure, wherein the laminated glass structure withstands a ball drop test wherein a 535 g stainless steel ball is dropped from a height of 0.8 m onto the laminated glass structure, with the glass sheet being impacted by the ball. The glass sheet has a thickness such that the glass sheet exhibits, without cracking, deformation to adapt to any shape change of the non-glass substrate as imparted by the ball of the ball drop test.

Abstract: A method of forming a laminated glass structure includes introducing a continuous ribbon of flexible glass substrate having a thickness of no greater than about 0.3 mm to a substrate material. The substrate material has a coefficient of thermal expansion (CTE) that is greater than that of the flexible glass substrate. The flexible glass substrate is laminated to the substrate material at an elevated temperature. The substrate material is cooled to introduce a compressive stress across a thickness of the flexible glass substrate.
