MULTILAYER GLASS POLYMERIC COMPOSITION Russian patent published in 2002 - IPC

FIELD: polymers. SUBSTANCE: multilayer glass polymeric composition consists of glass-block having glass layers of different thickness and combined by glue interlayers and at least two polymeric films combined with a glass layer of the smallest thickness. Glue interlayers have a wave resistance maximally closed to a wave resistance of glass layers. Value of a wave resistance of glue interlayers is (11-13) x 10⁵ kg/(m² x s) and those of glass layers (30-50) x 10⁵ kg/(m² x s). Each following glass layer has a thickness less of a former layer. The first and second layers of glass can be made with a possibility of predestroying. Invention can be used for protection of compartments, cars from the nonsanctioned penetration and from small arms. EFFECT: decreased thickness of glass package, enhanced resistance against gun rupture and double glass pane, simplified method of glass package making. 3 cl, 1 dwg
