Abstract
The invention refers to a light-transmissive plastic plate structure suitable for vehicle sunroof with curved surface and a method for fabricating the same. By using polymer material formulation, UV resistant coating formulation and precision coating technology, the wear resistance of polymer surface of plastic substrate can be improved to the same level as glass, and the original optical and physical properties after various environmental tests can also be maintained. The plastic substrate is first formed into a curved plastic plate through a hot pressing process, and then a connecting structure is formed and fixed on the plastic plate by an insert-molding injection process, in order to replace the traditional car sunroof mechanism which is assembled by glass plate bonded with metal connecting parts. The light-transmissive plastic plate structure with curved surface comprises a lightweight polymer sunroof and a lightweight plastic connecting structure fixed to the sunroof by insert-molding injection, which can reduce the weight of traditional glass sunroof, front and rear windshield, and side window glass assembly, and is particularly suitable for use in oil-electric hybrid vehicl…
