TRANSPARENT FIBER REINFORCED RESIN SHEET

摘要

PROBLEM TO BE SOLVED: To provide a transparent fiber reinforced resin sheet securing a high glass transition temperature durable to surface processing while keeping a high transparency, and suppressing birefringence. SOLUTION: The transparent fiber reinforced resin sheet 1 is composed of a reinforced fiber layer formed of a base material 4 of transparent reinforced fiber and a resin layer formed of cured matters 5, 6 of curable transparent resin. The plurality of reinforced fiber layers are disposed in the thickness direction, and the resin layers are disposed between the respective reinforced fiber layers and on both outer sides of the outermost reinforced fiber layer. The glass transition temperature of the cured matter 6 of the curable transparent resin of the resin layer of the outermost layer is higher than that of the cured matter 5 of the curable transparent resin of the resin layer disposed between the respective reinforced fiber layers.
