MULTI-LAYERED TRANSPARENCY AND METHOD OF PRODUCING SUCH A MULTI-LAYERED TRANSPARENCY
First Claim
1. A multi-layered transparency for an aircraft cockpit, particularly a multi-layered window for a helicopter cockpit, comprising:
- one core layer made of a polymer of either polycarbonate (PC) or microcrystalline polyamide (mcPA);
at least one foil extruded, adhesive interlayer film unilaterally bonded to said at least one core layer;
at least one outer top layer made of microcrystalline polyamide (mcPA), preferably containing additives, said at least one outer top layer being unilaterally attached to said at least one foil extruded adhesive interlayer film distal to said at least one core layer; and
a scratch resistant outer top coating, provided unilaterally to said at least one outer top layer distal to said at least one foil extruded adhesive interlayer film;
wherein at least one foil extruded adhesive interlayer film comprises two foil extruded films with a functional layer in between.

Abstract
A multi-layered transparency (2.1, 2.2) for an aircraft cockpit, particularly a multi-layered window for a helicopter cockpit (1), comprising: one core layer (6) made of a polymer of either PC or mcPA and at least one foil extruded, adhesive interlayer film (3.1, 3.2, 3.3) unilaterally bonded to said at least one core layer (6). At least one outer top layer (5.1, 5.2) made of mcPA, preferably containing additives, is unilaterally attached to said at least one foil extruded adhesive interlayer film (3.1, 3.2, 3.3) distal to said at least one core layer (6) and a scratch resistant outer top coating (4.1, 4.2) is provided unilaterally to said at least one outer top layer (5.1, 5.2) distal to said at least one foil extruded adhesive interlayer film (3.1, 3.2, 3.3). The invention is as well related to a method of producing such a multi-layered transparency.
