CONTAINING AN ACRYLIC POLYMER SHEET AIRCRAFT GLAZING, HAVING IMPROVED MECHANICAL PROPERTIES Russian patent published in 2020 - IPC B64C1/14 B32B17/10 B32B7/12 

FIELD: glass industry; aviation.

SUBSTANCE: invention relates to aviation glazing units, the use of which is particularly demanding for collision with a flight of birds, pressure drops and very low temperatures. Aircraft glazing unit comprises at least one sheet of modified acrylic polymer, which is a chemically modified acrylic polymer, containing in its polymer chain blocks, which are nanostructured and/or supplemented with micro fillers or nanofillers, which limit distribution of cracks, wherein the sheet is combined with at least one other sheet as a laminated and/or multiple glazing unit.

EFFECT: invention provides glazing with high level of mechanical strength, transparency and optical quality, which are preserved for a long time.
