Experimental Evaluation of Laminated Glass Interlayer Polymers at Various Strain Rates and Temperatures
Abstract
The use of blast-resistant glazing, such as laminated glass in buildings can greatly reduce, if not eliminate, the hazard of flying glass shards. In a failure event, fractured glass shards adhere to the polymer interlayer, and do not fly or fall. Under dynamic loading scenarios such as blast, the interlayer deforms largely, providing post-cracking energy absorption to the laminated glass system. When properly designed, laminated glass polymer interlayers are capable of maintaining the integrity of the building envelope in extreme events such as blasts or hurricanes, protecting the interior from damage. Analytical and experimental research exists in the literature in the area of blast-resistant glazing; however, more research on the dynamic response of polymer interlayer materials is necessary to understand the post-cracking behavior of blast-resistant window systems. Therefore, the main objective of this research is to experimentally evaluate the high strain rate and temperature effects on the dynamic response of pre-laminated PVB and SG polymers.
