METHODS AND APPARATUS FOR FABRICATING AND CUTTING FLEXIBLE GLASS AND POLYMER COMPOSITE STRUCTURES

摘要

Methods and apparatus provide for: sourcing an ultra-thin glass sheet having first and second opposing major surfaces and perimeter edges therebetween, the glass sheet having a thickness between the first and second surfaces of less than about 400 microns; adhering at least one polymer layer directly or indirectly to at least one of the first and second surfaces of the glass sheet to form a laminated structure; and cutting the laminated structure using at least one of the following techniques: shear cutting, burst cutting, slit cutting, and crush cutting.

1. A method, comprising:
sourcing an ultra-thin glass sheet having first and second opposing major surfaces and perimeter edges therebetween, the glass sheet having a thickness between the first and second surfaces of less than about 400 microns; adhering at least one polymer layer directly or indirectly to at least one of the first and second surfaces of the glass sheet to form a laminated structure; and cutting the laminated structure using at least one of the following techniques: shear cutting, burst cutting, slit cutting, and crush cutting, wherein the cutting step produces at least one cut edge having an edge characteristic in which lateral cracks running from the cut edge into the glass sheet penetrate no further than one of: (i) about 1400 microns; (ii) about 1000 microns; (iii) about 800 microns; (iv) about 600 microns; and (v) about 400 microns; (vi) about 200 microns; (vii) about 100 microns, and (viii) about 50 microns.
