摘要

PROBLEM TO BE SOLVED: To provide a transparent sheet which allows for improvement in the initial tear strength thereof and furthermore allows for improvement and maintenance in the transparency thereof when a glass fiber fabric is thin in a transparent resin composite of a glass fiber and a resin.;SOLUTION: A transparent sheet 1 is provided which includes: a glass fiber fabric 2 having a thickness of 8-30 μm; a curable resin composition layer 3 included in such a state that the curable resin composition layer 3 is impregnated in the glass fiber fabric; and a thermoplastic resin layer 4 which is laminated on the curable resin composition layer and includes a thermoplastic resin other than a polyvinyl chloride resin. The curable resin composition layer is formed by curing a resin composition including acrylic syrup. The glass fiber fabric is a woven fabric, each of glass yarns constituting the woven fabric has an average filament diameter of 3.5-4.5 μm and the number of filaments of 20-110, and the woven fabric has a woven density of 80-120/25 mm together with weft, a thickness of 9-30 μm, and a mass of 9-35 g/m2.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
