Polyvinyl Butyral (PVB) and Ethyl Vinyl Acetate (EVA) as a Binding Material for Laminated Glass

The effect of the type of the bonding interlayer on the mechanical behavior of laminated glass was studied in this paper. Furthermore, this investigation presents mathematical models that helps in predicting this behavior based on the glass plate thickness and the type and thickness of the bonding material. Both practical results and the theoretical model indicate that the failure strength of laminated glass bonded with either PVB or EVA decreases as the interlayer thickness increases. Moreover, the failure strength of the glass bonded with EVA is greater than that for the PVB bonded ones under the same conditions. On the other hand, it was observed that the ability of laminated glass to absorb energy increases with the increase of the interlayer thickness and the increase of glass plate thickness.
