Reinforced Transparencies for Aerospace Application – Case Description

ABSTRACT This paper describes the polycarbonate acrylic laminated development that can be applied in aeronautics and aerospace transparencies. The case studied is a laminated double-curved transparency (bubble form) used in an observation side window of a military aircraft. Side windows need strength and specific characteristics, similar to windshields, allowing the perfect visualization and image capture. Laminated transparencies composed by different materials have better qualities than the monolithic ones. This kind of transparency can offer high mechanical and chemical resistance, high transparency, no fragmentation and easy maintenance or recovery. A significant amount of information about materials and processes was jointed in order to build the reinforced transparency and validate this study. The final results were analyzed based on two points of view: mechanic resistance and, especially, optical quality.

摘要 本文介绍了可应用于航空航天透明结构件的聚碳酸酯丙烯酸酯层压材料的研发工作。本次研究的案例为一款应用于军用飞机侧部观察窗的双曲曲面层压透明结构件（气泡造型）。侧窗与飞机挡风玻璃类似，需具备优异的强度与特定性能，以保障清晰可视与图像采集。由不同材料复合而成的层压透明构件，其性能优于单片式构件。这类透明结构件可兼具高机械强度与化学耐受性、高透光率，且无碎裂风险，同时便于维护与修复。研究整合了大量材料与工艺相关信息，以制备增强型透明结构件并验证本研究的有效性。最终结果从两大维度展开分析：机械强度，以及尤为核心的光学性能。
