LIGHT-WEIGHT HYBRID GLASS LAMINATES

摘要

A glass laminate comprises an external glass sheet, an internal glass sheet, and a polymer interlayer formed between the external glass sheet and the internal glass sheet. The external glass sheet can be a thin chemically-strengthened glass sheet or can be a non-chemically strengthened glass sheet, the polymer interlayer can have a thickness of less than 1.6 mm, and the internal glass sheet can be a non-chemically-strengthened glass sheet or a thin chemically strengthened glass sheet.

1. An automotive laminate comprising:
a non-chemically strengthened external glass sheet; a chemically strengthened internal glass sheet; and at least one polymer interlayer intermediate the external and internal glass sheets and comprising any one or more of poly vinyl butyral (PVB), polycarbonate, acoustic PVB, ethylene vinyl acetate (EVA), thermoplastic polyurethane (TPU), and ionomer, wherein the internal glass sheet has a thickness of 1 mm or less, and wherein the external glass sheet has a thickness ranging from about 1.5 mm to about 3.0 mm, wherein the internal glass sheet comprises an alkali aluminosilicate glass.
