US Patent:

20220339906, Oct 27, 2022

Filed:

Jul 8, 2022

Appl. No.:

17/860672

Inventors:

- CORNING NY, US
Guangli Hu - Berkeley Heights NJ, US
John Christopher Mauro - Boalsburg PA, US
Natesan Venkataraman - Painted Post NY, US

International Classification:

B32B 7/027
B32B 17/06

Abstract:

A glass article includes a glass core layer and a glass cladding layer adjacent to the core layer. A coefficient of thermal expansion (CTE) of the core layer is greater than a CTE of the cladding layer. The core layer has a tensile stress, and the cladding layer has a compressive stress. A retained strength of the glass article is a strength determined after abrasion of an outer surface of the glass article with 1 mL of 90 grit SiC particles for 5 seconds at an abrasion pressure, and a ratio of the retained strength at an abrasion pressure of 25 psi to the retained strength at an abrasion pressure of 5 psi is at least about 0.3.

C03C 21/00

Abstract:

A glass laminate includes a glass core layer having a core coefficient of thermal expansion (CTE) and a glass cladding layer adjacent to the core layer and having a cladding CTE that is less than the core CTE such that the core layer is in tension and the cladding layer is in compression. A stress profile of the glass laminate includes a compressive peak disposed between an outer surface of the cladding layer and an inner surface of the cladding layer.
