Reinforced transparencies for aerospace application case description

Abstract

This work describes the development of an acrylic laminated transparent compound that can be applied in aeronautics and astronautics transparencies. The case here studied, is a laminated double curved transparency (bubble form), used in an observation side window of a military aircraft. Side windows needs specific resistance and characteristics, like the windshields; it allows the perfect visualization and image capitation. Laminated transparencies composed by different materials, joint better qualities than monolithic, due this way achieves great mechanic and chemical resistance, high transparency, no spall and easy maintenance or recovering. Much information about materials and process was jointed, with the intention to build the reinforced transparence, and to make valid this information, by the analysis of the final results, in both of points of view: mechanic resistance and optical quality. © 2009 by the American Institute of Aeronautics and Astronautics, Inc.
