Abstract

Products from organic glasses are widely used in aviation engineering for different types of glazing which work in difficult operational conditions, for example, are exposed to influence of low and high temperatures, moisture, ultra-violet radiation, etc. These factors can influence operational reliability of organic glass. Now application of the oriented polymethyl methacrylate AO-120 organic glass is most widespread in designs of aviation glazing. In the real work results of research of microstructure of surfaces of the AO-120 or-ganic glass which has undergone long influence of atmospheric factors in different climatic zones of the USA (Arizona and Florida) are provided.
