ABSTRACT:
A base sheet of transparent polycarbonate material has a formed shape including a center portion and a peripheral portion. The center portion is formed by a non-contact forming operation occurring at a temperature above the glass transition temperature and below the melt temperature of the transparent polycarbonate material, thereby resulting in the center portion of the base sheet being free of visual distortion. A top coat layer is disposed over the base sheet. The top coat layer has a greater resistance to abrasion than the polycarbonate material and provides UV protection to the base sheet. A primer coating is disposed between the base sheet and the top coat layer to facilitate bonding therebetween. The peripheral portion can have a shape created by a contact forming operation occurring at a temperature above the glass transition temperature and below the melt temperature of the polycarbonate material.
