Abstract

Oriented acrylate organic glass is currently the main glazing materials of most domestic aircraft and helicopters, occupying from 90 to 100% of the total glazing area. Physico-mechanical and optical characteristics of oriented рlexiglas provide high reliability and service life of aviation glazing up to 10 years and more. However the need for continuous improvement and complication of operating conditions of aircraft require glazing to increase the life of the airframe (more than 20–30 years). The solution to this problem is achieved by the introduction of technologies for grinding and polishing of organic glasses in the process of their manufacture, processing, operation and repair to remove surface defects of varying complexity with the help of polishing and grinding pastes developed and manufactured by FSUE «VIAM».
