Abstract (en)
[origin: WO2020020549A1] The invention relates to a method for producing a composite pane (100) comprising a functional element (5) having electrically controllable optical properties, wherein at least a) a first pre-composite (3) consisting of a first thermoplastic composite film (3a) and a first barrier film (3b) as well as a second pre-composite (4) consisting of a second thermoplastic composite film (4a) and a second barrier film (4b) are provided, and the pre-composites (3, 4) are cut substantially to the dimensions of the composite pane (100) to be produced, b) the barrier films (3b, 4b) are peripherally trimmed (7), c) a first pane (1), the first pre-composite (3), a functional element (5), the second pre-composite (4) and a second pane (2) are arranged one above the other in this order, wherein the barrier films (3b, 4b) are arranged in a planar manner directly adjacent to the functional element (5), enclose the peripheral edge (8) of the functional element (5), and at least sections of which touch one another in a planar manner in a projection u projecting beyond the functional element (5), d) the stack of layers consisting of, in this order, a first pane (1), a first thermoplastic composite film (3a), a first barrier film (3b), a functional element (5), a second barrier film (4b), a second thermoplastic composite film (4a), and a second pane (2) is joined by autoclaving to form a composite pane (100).
