Abstract
A method for fabricating a spectacle frame made of a cellulose acetate sheet embedded with the metal piece, where the metal piece is embedded between a main material and auxiliary materials; the metal piece, the main material, and the auxiliary materials are tightly bonded by pressing by a hydraulic press. Since the metal piece is not in contact with a human body, there will be no corrosion problems. The composite plate structure resulting from splicing of the main material and the auxiliary materials have better mechanical performance.
