Problems solved by technology

But in general no dimensions are given in this prior art
However, due to the relatively high thickness of the plastic carrier material compared to the thickness of the glass coating, this composite panel also does not meet the fire protection requirements imposed, for example, by aviation regulations

Abstract

The present invention relates to a lightweight composite panel which comprises at least one mineral glass or glass-ceramic panel and at least one organic layer A. The weight per unit area of the lightweight composite panel is in the range from 0.5 kg / m<2> to 5.5 kg / m<2>, the ratio of the total thickness of the one or more mineral glass or glass-ceramic panels to the total thickness of all of the organic layers is from 1:0.01 to 1:1 and the total thickness of all of the organic layers is less than or equal to 350 [mu]m. The lightweight composite panel complies with the thermal safety requirements of the air travel authorities and its Total Heat Release measured in accordance with JAR / FAR / CS 25, App. F, Part IV & AITM 2.0006 is less than 65 kW * min. / m<2> and its afterflame time after removal of the flame in the "Vertical Bunsen Burner Test" measured in accordance with FAR / JAR / CS 25, App. F, Part I & AITM 2.0002A is less than 15 sec. The invention further relates to a lightweight window pane, more particularly an inner pane of an aircraft window, and to a smoke barrier element.

Description

technical field [0001] The invention relates to a composite part having a composite of at least one mineral glass layer or mineral glass-ceramic ply and at least one organic layer adjoining the glass or glass-ceramic layer, as well as a method for its production and the use of the composite part elements, and has a low overall areal weight and low heat release rate. Furthermore, the invention includes aircraft interior glazing or lightweight glazing and smoke arresting components having such a composite element. Background technique [0002] Glass / plastic composite panels for land, water and air vehicles as well as for the construction sector and the interior sector are described in various ways in the prior art and fulfill the many requirements set forth. However, some applications, in particular in the field of transportation, for example in the fields of aircraft construction and electric vehicle construction, impose special requirements for which there has been no solut...
