Laminated glass windows are becoming increasingly popular in the structures industry. Because of this, new polymer interlayer materials are being developed to better serve the purposes of building design, rather than windshield design, which was the original purpose. Since buildings are designed to stand the test of time, it is important to understand how the laminated glass windows, and in turn the polymer interlayer materials, will behave after weathering action. It is known that weathering action has a significant impact on polymer interlayer materials, and previous studies have evaluated certain aspects of weathering such as temperature, humidity, and UV radiation. The purpose of this research is to gain a better understanding of the difference in impact of weathering on various emerging polymer interlayer materials. This study will take a brief look at the effects of strain rate on the mechanical behavior of polymer interlayers before focusing on the effects of water absorption and outdoor weathering on PVB, EVA, and SG. The mechanical behavior will be evaluated using quasi-static and high strain rate testing after exposure to weathering conditions. In addition, the difference in natural aging of polymers between two glass plies will be compared to those with direct exposure to investigate the impact of the glass on the weathering affects. The research presented herein is ongoing, and the full scope of the project will be discussed as future work.
