Performance of Sentry Glass Plus (SGP) Interlayer Laminated Glass Subjected to Air Blast Loading

Abstract

This paper presents the result of the field blast test conducted on the laminated glass with Sentry Glass Plus ( SGP ) as an interlayer and laminated glass with PVB interlayer as control sample. The objective of this research was to investigate the blast resistance of laminated glass with SGP interlayer and laminated glass with PVB interlayer. In this research a field blast testing was carried out using ASTM F 1642-04 to obtain the blast related data and also to investigate the behaviour of the laminated glass subjected to air blast loading. The blast test result shows that laminated glass with SGP interlayer and laminated glass with PVB interlayer able to withstand the peak overpressure of 337.84 kPa and reflected pressure of 4688.43 kPa. Therefore, there is potential for the SGP interlayer to be use as an interlayer in the blast proof glass.
