PVB laminated glass consists of a single piece of glass and PVB film layers. In order to explore the application of glass plate technology to the mechanical properties of ordinary vehicle road panels, it is particularly important to test the material properties of both for studying the overall mechanical properties of laminated glass. The material properties of glass are relatively clear, and the constitutive parameters are more evidence-based. PVB belongs to polymer materials, and its mechanical properties are influenced by various factors such as temperature, loading rate, strain rate, etc. The determination of elastic modulus values and constitutive relationships under different conditions is relatively complex and usually requires experimental research. By studying the uniaxial tensile properties of PVB interlayer materials at different loading rates, the uniaxial tensile experimental phenomena, uniaxial tensile stress-strain curve, uniaxial tensile constitutive relationship, uniaxial tensile elastic modulus and its rate correlation of PVB materials were analyzed, which is helpful for further research on the mechanical properties of laminated glass under wheel compression load.
