Abstract: Aspects of this disclosure relate to a method for selecting an adhesive for bonding a cold-formed glass to a metal substrate and various cold-formed products. In one or more embodiments, the cold-formed products include a structural substrate comprising a curved surface and structural substrate coefficient of thermal expansion (CTE), a cold-formed and curved glass substrate attached to the curved surface with an adhesive, the glass substrate comprising a glass substrate CTE, the structural substrate and adhesive forming a structural substrate/adhesive interface and the glass substrate and the adhesive forming a glass substrate/adhesive interface, wherein the glass substrate CTE and the structural substrate CTE differ, wherein the product withstands overlap shear failure as determined by modified test method ASTM D1002-10 at −40° C., 24° C., and 85° C. and tensile failure as determined by ASTM D897 at −40° C., 24° C., and 85° C. at one or both of the structural substrate/adhesive interface and the glass substrate/adhesive interface.

Abstract: Emobidments of a curved glass article are disclosed herein. The curved glass article includes a glass sheet first and second major surfaces. The glass sheet is bent to define a curved region disposed between flat sections. The curved glass article also includes a carrier adhered to the glass sheet. The carrier includes longitudinal strips and lateral strips. The longitudinal strips define the radius of curvature of the curved region. The lateral strips extend between the longitudinal strips. The glass sheet deviates 0.3 mm or less from planar in the flat sections. The longitudinal strips each have a width Wlong of 2 mm or less. The first lateral strips each have a width Wlat of 20 mm or less. At least a portion of the width Wlat of each lateral strip is located in the curved region and a flat section.

Abstract: Disclosed is a glass article. The glass article includes a cold-formed glass sheet having a first major surface and a second major surface. The second major surface is opposite to the first major surface. The first major surface has a curvature with a variable radius of curvature including a minimum radius of curvature at a vertex of the curvature. The curvature extends in a first direction from the vertex and in a second direction from the vertex. The first direction is opposite to the second direction. The variable radius of curvature continuously increases with increasing distance from the vertex in the first direction and in the second direction.

Abstract: Disclosed is a method of forming a glass article. In the method, a mid-frame is adhered to a glass sheet in a flat configuration. The glass sheet has a first major surface and a second major surface opposite to the first major surface. The mid-frame is adhered to the second major surface of the glass sheet. The glass sheet and mid-frame are bent over a forming surface of a chuck so that the glass sheet is in a curved configuration. The forming surface includes a first radius of curvature of 20 mm or more, and the first major surface of the glass sheet conforms to the forming surface. A frame is attached to the mid-frame, and the frame holds the glass sheet in the curved configuration.

Abstract: Disclosed herein are embodiments of a curved glass article. The curved glass article includes a glass sheet having a first major surface and a second major surface. The second major surface is opposite to the first major surface, and the first major surface and the second major surface define a thickness therebetween. The curved glass article also includes a carrier having a curvature and being made of a carrier material. The carrier material has a coefficient of thermal expansion (CTE) of from 8(10−6)/° C. to 40(10−6)/° C. The glass sheet is adhered to the carrier such that the glass sheet conforms to the curvature of the carrier.
