  • Glass composition for glass fibers, glass fiber, and glass fiber-reinforced resin molded product
    Patent number: 11884586
    Abstract: Provided is a glass composition for glass fiber that suppresses variations in fiber diameter of glass fiber including 45.60 to 59.00% by mass of SiO2, 10.00 to 16.00% by mass of Al2O3, 17.00 to 25.00% by mass of CaO, 0.01 to 9.50% by mass of TiO2, 0.03 to 7.00% by mass of P2O5, 0.00 to 9.50% by mass of ZnO, 0.00 to 2.00% by mass of SO3, 0.01 to 11.50% by mass in total of ZnO and SO3, and 0.00 to 2.00% by mass in total of Na2O, K2O, and Li2O, with respect to the total amount. The content SI of SiO2, the content A of Al2O3, the content C of CaO, the content T of TiO2, the content P of P2O5, the content Z of ZnO, and the content SO of SO3 satisfy the following formula (1): 15.0?(SI/C)2×(A/T)×{P/(SO+Z)}1/4?690.1??(1).
