Abstract
A flexible glass laminate structure includes a flexible glass substrate having a thickness of no more than 0.3 mm. The flexible glass laminate structure includes a flexible glass layer including the flexible glass substrate. A property control layer is laminated to the flexible glass layer. A neutral axis of the flexible glass laminate is located outside the flexible glass layer when the flexible glass layer is in a compressive bend configuration.
Claims20
A flexible glass laminate structure comprising:
- a flexible glass layer comprising a flexible glass substrate having a thickness of no more than 0.3 mm;
- and
- a property control layer laminated to the flexible glass layer;
- wherein the property control layer has an effective stiffness to unit area weight ratio of between about 0.03 Nm3/kg and about 0.4 Nm3/kg;
- and
- wherein a neutral axis of the flexible glass laminate structure is located outside the flexible glass layer when the flexible glass layer is in a compressive bend configuration.
A method of forming a flexible glass laminate structure, the method comprising:
- laminating a flexible glass layer and a property control layer together, the flexible glass layer having a thickness of no more than 0.3 mm;
- and
- locating a decorative pattern between the flexible glass layer and the property control layer such that the decorative pattern is visible through the flexible glass layer;
- wherein a neutral axis of the flexible glass laminate structure is located outside the flexible glass layer eliminating tensile stress in the flexible glass layer when the flexible glass layer is in a compressive bend configuration.
A roll of a flexible glass laminate structure comprising:
- a flexible glass layer having a thickness of no more than 0.3 mm and a property control layer laminated to the flexible glass layer;
- the flexible glass laminate structure wound about a center of the roll to an inner diameter of at most about 30 inches;
- the flexible glass layer located on an inner facing side of the flexible glass laminate structure such that a neutral axis of the flexible glass laminate structure is located outside the flexible glass layer eliminating tensile stress in the flexible glass layer.
