  • Publication number: 20210078304
    Abstract: The present disclosure relates to a method for manufacturing curved laminated glass and curved laminated glass manufactured by the same. The method includes providing a curved thick plate glass; providing a thin plate glass whose thickness is smaller than that of the curved thick plate glass; stacking a support film comprising a ductile layer and an elastic layer on one surface of the thin plate glass; positioning a lamination film or a bonding agent between the other surface of the thin plate glass and a concave surface of the curved thick plate glass; and laminating the thin plate glass so as to be aligned with a concave surface of the curved thick plate glass by elastically deforming the thin plate glass provided with the support film.
