Abstract

Aviation glass aging is a potential risk, so it is necessary to verify the airworthiness of aviation glass aging. In this paper, the normal aircraft takes aviation composite glass as the research object. First, based on the airworthiness regulations of China's civil aviation, the airworthiness clauses CCAR 23.2235, CAAR 23.2250, CCAR 23.2260 and CCAR 23.2260 of aviation glass are interpreted, and the airworthiness requirements of glass aging verification are given. Based on the requirements of the article, the influence of the ageing environment on the glass was analyzed, and the mechanical properties and thermal stability of the aerospace glass after ageing were verified and analyzed using the MOC2 and MOC4 compliance methods. The results of the study were also used to propose a complete validation process, along with review focus and review recommendations for the validation of composite glass ageing. The final results show that the PMMA pitch section is subjected to greater force and deformation, while the ageing of the composite glass is mainly based on PMMA. As the ageing time increases, the ageing environment changes the internal structure of the Plexiglas, causing the breaking strain and ultimate stress of the glass to decrease significantly, the tensile strength of the glass decreases, the resistance to deformation is weakened, and the thermal stability temporarily increases, with the overall trend increasing first and then decreasing.
