TRANSPARENT LAMINATED PLATE

摘要

PROBLEM TO BE SOLVED: To provide a transparent laminated plate for securing high transparency while suppressing the occurrence of crack or separation. SOLUTION: A resin composition is prepared with its refractive index approximate to that of a glass fiber by mixing a high refractive index resin having a higher refractive index than the glass fiber and a low refractive index resin having a smaller refractive index than the glass fiber. It is hardened while impregnating a glass fiber substrate to form the transparent laminated plate. A bisphenol type epoxy resin is used as the high refractive index resin, and a hydrogenated bisphenol type epoxy resin is used as the low refractive index resin. The hydrogenated bisphenol type epoxy resin is used as the low refractive index resin to suppress the occurrence of crack or separation on interfaces between the glass fiber substrate and the epoxy resin.
