For this reason, the multi-layer glass 100, 200 is thin, and the total weight is significantly reduced. Therefore, even if the multi-layer glass 100, 200 according to the present invention is installed as a transparent member of the vehicle 400, there is a need for the transparent member to protrude remarkably or to separately use a reinforcing member for supporting the multi-layer glass.

Abstract

La présente invention concerne un verre feuilleté qui peut être plus léger et plus mince qu'un verre feuilleté sous vide traditionnel. Ledit verre feuilleté est caractérisé en ce qu'il comprend un premier corps stratifié obtenu par dépôt, dans l'ordre indiqué, d'une première couche de verre, d'une première couche de polycarbonate et d'une deuxième couche de verre ; un second corps stratifié obtenu, par dépôt, dans l'ordre indiqué, d'une troisième couche de verre, d'une seconde couche de polycarbonate et d'une quatrième couche de verre ; et un vide situé entre le premier corps stratifié et le second corps stratifié. Ledit verre feuilleté est encore caractérisé en ce que l'épaisseur des première et deuxième couches de verre varie de 0,05 à 1,50 mm ; en ce que l'épaisseur des troisième et quatrième couches de verre varie de 0,05 à 1,50 mm ; et en ce que l'épaisseur des première et seconde couches de polycarbonate varie de 0,10 à 8,00 mm.
