Abstract
The method of fabrication of a laminate formed by at least two transparent sheets consists in forming a stack of sheets after coating the sheet interfaces with a polymerizable adhesive, in subjecting the stack to an overpressure below or equal to 2 bar, in maintaining at the same time a temperature T below the maximum temperature of stability of the adhesive for a sufficient period of time to obtain prepolymerization of the adhesive, then in maintaining the stack temperature below or equal to the temperature T for a period of less than sixteen hours.
