Composite glazing material made of glass and plastic and process for determining the optimal geometric parameters of this glazing material

摘要

The invention relates to a composite glazing material of the type including two sheets of glass and an interlayer of transparent plastic of greater thickness than the thickness of the sheets of glass, characterized in that the plastic is capable of adhering to the glass.The glazing material has a total thickness smaller than 5 mm, a ratio of the thickness of the interlayer to the thickness of the sheets of glass of between 1 and 10, a mass per unit area lower than 6 kg/m2 and a Young's modulus higher than 30 GPa at a total thickness of glazing material of 3 mm.
