Patent ID: 11827770

Abstract:
Provided is a glass fiber-reinforced resin molded article having high dimension stability and low dielectric characteristics. In the glass fiber-reinforced resin molded article, the fiber diameter D of glass fiber included in the glass fiber-reinforced resin molded article is in the range of 5.0 to 15.0 μm, the dielectric constant Dk at a measurement frequency of 1 GHz of the glass fiber is in the range of 4.0 to 7.0, the linear expansion coefficient C of the glass fiber is in the range of 2.0 to 6.0 ppm/K, the number average fiber length L of the glass fiber is in the range of 150 to 400 μm, and the D, Dk, C, and L satisfy the following formula (1): 57.9≤Dk×C1/4×L1/2/D1/4≤70.6  (1)
