In recent years, there have been many examples of pedestrian bridges using GFRP as the main structural material because of its properties such as high strength, high corrosion resistance, and light weight. However, this material has not been applied to road and rail bridges in Japan. Because these bridges are heavier and have more severe design requirements than footbridges, it is unknown whether the material properties of GFRP can satisfy these requirements. It is also considered that thick FRP members will be required to satisfy the design requirements of the bridges. Based on this background, we tried to verify the forming of 40 mm thick GFRP by the hand layup method and evaluated the mechanical properties of GFRP. As a result, fundamental material properties for structural design were provided.
