Abstract
A glazing unit comprising a transparent laminate of three layers of dissimilar synthetic plastic materials and a method for manufacturing the same. Each layer comprises either a thermoplastic or thermoset synthetic plastic material. The three transparent layers include a clear layer of an acrylic, polymethyl methacrylate (PMMA) material, an interlayer of a polyurethane or a polyvinyl butyral (PVB) material, and a layer of a polycarbonate material. This construction provides a lightweight, durable, and transparent glazing unit capable of being utilized as a window in a vehicle or aircraft. The acrylic layer and polycarbonate layer are coated on all surfaces with an abrasion-resistant surface-hardening film. A multi-layer weather-resistant coating having a hydrophilic component and a hydrophobic component are applied to at least one of the outer surfaces of the glazing unit.
