Air Force service experience with state-of-the-art transparent plastics has demonstrated the need for improved materials. A project was started to evaluate research samples of copolyester-carbonate PEC plastics received from the Allied Corporation as a result of a research and development contract funded by the Materials Laboratory of the Air Force Wright Aeronautical Laboratories. Mechanical, physical and chemical properties of the PEC materials were evaluated in order to assess the potential to the material for use in aircraft transparencies. It was found that the PEC materials possess several advantages over the state-of-the-art polycarbonate plastics and that the materials showed promise for use in high performance transparencies.
