Abstract:
1. A process for manufacturing a laminated glazing unit product so that it withstands a predetermined stress, comprising: at least one substrate having a glass function and a first chemical composition; and at least one polymer interlayer having a second chemical composition, the process comprising: identifying a reference laminated glazing unit that withstands the predetermined stress and that comprises at least one substrate having the first chemical composition of the at least one substrate of the laminated glazing unit product, and at least one interlayer having the second chemical composition; determining a tear strength (J graphing a minimum interlayer tear strength (J deducing from the graph a combination of optimum values (e sizing the laminated glazing unit product to withstand the predetermined stress with a chosen interlayer thickness (e wherein the minimum interlayer tear strength (J
