Transparent glass/polymer composite

摘要

A transparent device for protection from an action of shock, projectiles, fragments or shock waves is provided. The device is a laminate having brittle-fracture, transparent materials that are joined together by way of transparent intermediate layers of organic polymers. The laminate is closed on the protective side facing away from the side of action by a fragment-protective layer that is formed as a transparent polymer layer in a thickness of 0.5 mm to 12 mm. The laminate has facing the side of action a chemically prestressed, brittle-fracture panel that is at a distance of 3 mm to 20 mm from the side of action.

主权项

1. A transparent device for protection from an action of shock, projectiles, fragments or shock waves, comprising:
a laminate having four brittle-fracture, transparent panels that are joined together by transparent intermediate layers, the transparent intermediate layer being formed of casting resin or being formed of polymer film, the laminate having a total thickness of at least 60 mm and the laminate being closed, on a protective side facing away from a side of action, by a fragment-protective layer having a thickness of 0.5 mm to 12 mm, which is formed as a transparent polymer layer, the laminate being closed on a side facing the side of action by one of the four brittle-fracture, transparent panels that comprises a first, chemically prestressed, brittle-fracture panel; and a polymer layer of a thickness between 2 mm and 15 mm is disposed via a polyurethane layer on a surface of the first, chemically prestressed, brittle-fracture panel that faces away from the side of action.
