Abstract:
This disclosure is directed to laminates for transparent armor application and in particular to laminates comprising at least one layer of an intermediate or anomalous glass. Anomalous glasses include glasses with a SiO 2 content (in mol %) greater than 80 mol %, and the glasses can contain other elements that give the glass highly desirable properties such as impact resistance. Examples include Corning ULE glass 4 wt% to 2 with the remainder being SiO 2 , fused silica, and Vycor. An additional type of glass that can be used in the laminates described herein are "intermediate" glasses; for example, an aluminoborosilicate impact resistant glass comprising 60-72 mol% SiO 2 ; 9-16 mol% Al 2 O 3 ; 5-12 mol% B 2 O 3 ; 8-16 mol% Na 2 O; and 0-4 mol % K 2 O that is ion exchanged with potassium ions to form a chemically strengthened glass.
Abstract:
A glass and an enclosure, including windows, cover plates, and substrates for mobile electronic devices comprising the glass. The glass has a crack initiation threshold that is sufficient to withstand direct impact, has a retained strength following abrasion that is greater than soda lime and alkali aluminosilicate glasses, and is resistant to damage when scratched. The enclosure includes cover plates, windows, screens, and casings for mobile electronic devices and information terminal devices.
