old news not posted here but worth noting. От ракеты до «Кометы»: самые знаковые проекты «Технологии» (rostec.ru)

"In Russia, the Obnin enterprise was the first to use polycarbonate in aviation. In the world before that only two countries had such an opportunity - the United States and China. But here it is worth noting the very technology of obtaining the product. Americans and Chinese get polycarbonate glazing products by casting under pressure, which is a fairly laborious and energy-intensive production. Our "Technology" has learned to form a sheet of optical polycarbonate, that is directly from the sheet of polycarbonate to make the right product. It is clear that there were no ready machines for this, and it was necessary to come up with from scratch. As a result, the company developed and implemented unique equipment, which does not exist.

Polycarbonate glass is one and a half times stronger than silicate, which is traditionally used in aviation, while polycarbonate is one and a half times lighter. Another positive thing is that such glass does not give cracks and shrapnel in a collision. Today, polycarbonate glasses from ONPP "Technology" are equipped with the most modern aircraft. They are already on the Su-57 fighter, work is underway on the glazing of the Ka-62 helicopter. The new glazing technology helps to significantly improve the safety of not only aircraft. Polycarbonate glass is used on new passenger ships on the underwater wings of Comet 120M. In July 2018, the ship began to cruise the Black Sea routes."
