Abstract
A laminate includes a polycarbonate substrate and an ultraviolet hard coat film disposed on the polycarbonate substrate. The ultraviolet hard coat film may include a polyethylene terephthalate (PET) layer, an adhesive interposed between the PET layer and the polycarbonate substrate, and an exterior hard coat disposed on the PET layer opposite the polycarbonate substrate. The exterior hard coat may include UV stabilizers. The laminate may include additional ultraviolet hard coat films stacked on the ultraviolet hard coat film. The laminate may be thermoformed into the shape of a curved vehicle windshield.

A laminate comprising:
- a polycarbonate substrate;
- a stack of one or more polyethylene terephthalate (PET) films disposed on the polycarbonate substrate, the stack of one or more PET films including an exterior hard coat opposite the polycarbonate substrate;
- and
- an interior hard coat disposed on the polycarbonate substrate opposite the stack of one or more PET films, the interior hard coat being softer than the exterior hard coat.
A laminate comprising:
- a polycarbonate substrate;
- a stack of one or more polyethylene terephthalate (PET) films adhered to the polycarbonate substrate by an adhesive, the stack of one or more PET films including an exterior hard coat opposite the polycarbonate substrate;
- and
- an interior hard coat disposed on the polycarbonate substrate opposite the stack of one or more PET films, the interior hard coat being softer than the exterior hard coat.
A method comprising:
- disposing a first hard coat on a stack of one or more polyethylene terephthalate (PET) films;
- disposing the stack of one or more PET carriers on a first side of a polycarbonate substrate;
- and
