Laminated glazing with improved resistance to relatively discrete impact types
A laminated glazing includes a structural transparent substrate bonded to a glass sheet of 0.5 to 4 mm, intended to constitute an outer surface of the laminated glazing, by an adhesive interlayer of 4 to 10 mm, which successively includes 0.25 to 2.5 mm of a flexible first polymer material having a...

| Abstract | A laminated glazing includes a structural transparent substrate bonded to a glass sheet of 0.5 to 4 mm, intended to constitute an outer surface of the laminated glazing, by an adhesive interlayer of 4 to 10 mm, which successively includes 0.25 to 2.5 mm of a flexible first polymer material having a relaxation modulus at most equal to 2 GPa for relaxation times at least equal to 10 min, at temperatures at least equal to −40° C., in contact with the glass sheet, then a stiff second polymer material having a relaxation modulus at least equal to 4 GPa, for time constants at most equal to 0.1 millisecond and temperatures at most equal to 40° C. |
