Composite Element and Use Thereof

摘要

A lightweight composite pane is provided that includes a mineral glass or glass-ceramic pane and an organic layer. The weight per unit area of the lightweight composite pane is in the range from 0.5 kg/m2 to 5.5 kg/m2, the ratio of the thickness of the mineral glass pane to the thickness of the organic layer is 1:0.01 to 1:1, and the thickness of the organic layer is less than or equal to 500 μm. The lightweight composite pane meets the thermal safety requirements of aerospace authorities and has a “Total Heat Release,” measured in compliance with JAR/FAR/CS 25, App. F, Part IV & AITM 2.0006, of less than 65 kW×min/m2 and a flame time, after removal of the flame in the “Vertical Bunsen Burner Test”, measured in compliance with FAR/JAR/CS 25, App. F, Part 1 & AITM 2.0002A, is less than 15 seconds.
