Properties of PVB Interlayer Used in Laminated Glass
Publication: Journal of Materials in Civil Engineering
Volume 4, Issue 1
Abstract
A thin elastomeric interlayer called polyvinyl butyral (PVB) is used to bond two or more thin glass plates to form a composite commonly called a laminated glass unit. Even though experiments have been performed to determine the load‐deformation characteristics, efforts to create a mathematical model for the stress analysis fall short of the nonlinear shear stress‐strain behavior of the PVB interlayer. Specially made laminated‐glass specimens with two interlayer thicknesses, 0.76 mm and 1.52 mm, are tested in a direct shear box testing apparatus. The average shear stress versus average shear strain are plotted. Variations of tangent and secant modulii are also plotted as a function of average shear strain. All tests are performed at very low strain rates, because the objective was to study the static behavior of laminated‐glass units.
