Three-point bending test of laminated glass with PVB and EVA interlayers at elevated temperature

This paper presents the experimental results of a three-point bending test conducted on laminated glass at elevated temperature in an environmental chamber. The focus of the present research was on bending stiffness degradation of the laminated glass in correspondence to elevated temperature. The t...

The focus of the present research was on bending stiffness degradation of the laminated glass in correspondence to elevated temperature. The tested specimens were made of two fully tempered glass plates bonded with EVA and PVB interlayers. For each type of laminated glass and set temperature, we prepared and tested 5 specimens. Each of the specimen was preconditioned to a set temperature before the experiment conducted in an environmental chamber. The tests were conducted at 23°C, 35°C and 60°C after the specimens had reached the defined contact temperature. During the experiment, the midspan deflection, longitudinal midspan deformation and the force at midspan were recorded. In the end, the behaviour of two different types of laminated glass plates was compared based on measured midspan deflection, deformations and stiffness degradation. Based on the results it can be seen that the laminated glass with EVA interlayer behaves stiffer and that the stiffness degradation is almost linear and slower in comparison to the specimens with PVB interlayer.
