Production of the home-made polymeric film for military and civil aviation, where high-strength glazing is required, has been launched at the Dzerzhinsk production site of the Kargin Research Institute of Polymers JSC (part of ONPP Technologiya) in the Nizhny Novgorod region.
As a result of research and development work a fundamentally new brand of high-strength heat-resistant polymer film for the manufacture of multi-layer transparent aviation glazing was obtained, the Research Institute of Polymers launched an area for the production of domestic material on an industrial scale. The equipment allows to produce up to 110 square meters of film with a thickness of 0.1-1.5 mm and a width of 1100 mm, the company said.
Polymer film is used to join multiple panes of glass into a triplex or pentaplex and enhances the quality of aircraft glazing. This material provides durability, allowing you to maintain high optical properties of the product of structural optics. Now the material is undergoing certification, after which it will start to be used in serial products. With the commissioning of the production line the production of multilayered glass for which the film is used will be fully localized in Russia, said the government of the Kaluga region, where Obninsk Research and Production Enterprise Tekhnologiya is located.
For the MC-21 aircrafts Tekhnologiya developed the cockpit glazing from high-strength pentaplex on the basis of monolithic polycarbonate. This type of multilayer material consists of two outer sheets of silicate glass, a polycarbonate layer and two adhesive layers. It is planned to use the development not only for MS-21 project, but also for substitution of imported products in other domestic products of aviation industry as well as in shipbuilding and railway industry.
The company also created a composition of materials capable of doubling the absorption of radio-electronic waves when applied to the glazing of the Su-57 aircraft. Scientists’ innovative development will make it possible to significantly reduce the visibility of the Russian combat aircraft for the enemy’s radar detection systems.
Production of polymeric film for aviation glazing in Russia was lost in the 90s after a number of specialized enterprises were closed, so imported material was used for such products. Within the framework of import substitution the specialists of Research Institute of Polymers created a new brand of high-strength heat-resistant polymer film and set up its serial production.
