Behaviour of laminated glass panels subjected to impact and air blast loading

Attacks directed towards vulnerable structures have caused considerable damages to personnel, equipment and also loss of life. Due to this, laminated glass has been adopted as a safety glass for building as it offer higher protection to human and surroundings even after the glass is cracked. The objectives of this research is to investigate performance for impact and blast resistance of LG PVB, LG EVA, LG PU
Resin and LG SGP. The methodology in this research is divided into three major parts. The first part is to determine the mechanical properties of the laminated glass with different interlayers. Second, experimental work for impact test was carried out using EN 356 and third is field blast testing carried out according to 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 impact test result shows that only LG SGP survived in the impact test using 5.5 kg of steel indenter at a distance of 1.15m and be able to absorbed a total of 65 Joule of impact energy. On the other hand, the blast test result shows that LG SGP, LG PU Resin and LG PVB able to withstand the peak overpressure of 337.84 kPa and reflected pressure of 4688.43 kPa with the SGP interlayer perform the best among all the other interlayers. While LG EVA failed
during the test. It is recommended that the SGP to be used as blast resistant glass for building subjected to terrorist attacks. This research is expected to contribute new knowledge on safety to human as glass is widely used in all areas.
