[0075] Formed by laminating a polymer layer to a glass layer with an adhesive layer using the S2S lamination method and a lamination temperature of approximately 22°C figure 1 A glass-polymer laminate of conventional construction as shown in . The glass layer consists of a CTE of 3.2 x 10 -6 ℃ -1 , Alkaline earth metal boroaluminosilicate glass with an elastic modulus of 74GPa. The polymer layer consists of a CTE of approximately 75 x 10 -6 ℃ -1 , PMMA with an elastic modulus of 3GPa. The adhesive layer is formed from an optically clear pressure sensitive adhesive having a lower modulus of elasticity than the polymer layer. The glass layer has a thickness of 200 μm. The polymer layer has a thickness of 5.6 mm. The adhesive layer had a thickness of 50 μm. The glass-polymer laminate was rectangular and initially had a width of 965 mm and a length of 2620 mm. The glass-polymer laminates were progressively cut to size 650mm x 2620mm, 650mm x 2000mm, 650mm x 1000mm and 650...

Abstract

A glass-polymer laminate includes a glass layer with a thickness of at most about 300 [mu]m and a polymer layer laminated to the glass layer. At all temperatures within a temperature range of about 16 DEG C to about 32 DEG C, the glass layer has a compressive stress and the glass-polymer laminate has a bow flattening force of at most about 150 N. A method includes laminating a glass layer to a polymer layer with an adhesive at a lamination temperature to form a glass-polymer laminate. The glass layer has a thickness of at most about 300 [mu]m. The lamination temperature is sufficiently high that, at all temperatures within a temperature range of about 16 DEG C to about 32 DEG C, the glass layer has a compressive stress. The lamination temperature is sufficiently low that, at all temperatures within the temperature range, the glass-polymer laminate has a bow flattening force of at most about 150 N.

Description

[0001] This application claims priority to US Patent Application No. 62 / 080764, filed November 17, 2014, the entire contents of which are incorporated herein by reference. [0002] background 1. Technical field [0003] The present disclosure relates to glass-polymer laminates, and more particularly, to glass-polymer laminates having predetermined stress and bending characteristics that enable the processing of these glass-polymer laminates Cutting and mounting without breaking them, the present disclosure also relates to methods and apparatus for forming these glass-polymer laminates. 2. Background technology [0004] Laminated glass structures can be used as components in the production of many appliances, automotive components, architectural structures or electronic devices. For example, laminated glass structures can be incorporated as protective glass into various end products such as refrigerators, backsplashes, decorative glazing or televisions. However, it is diffi...
